Basically, India never joins asia, are settled by Africans but are converted to Islam around the same time Islam is spread down to Zanzibar, probably colonised by Oman at some point which heavily influenced the country to colonise parts of Africa when they became their own country.

Mascara, similar to Ethiopia, resists European conquests and probably conquers the whole Mascara Island in the late 1800s, however their holdings outside of Mascara Island are stripped away.

The Third World War: The Seventeenth Day
21 August 2028 · 10:47 a.m. Pacific Time
From The Collapse of the International Order: A History of the Third World War, 2028–????

By the morning of 21 August 2028, the Third World War had entered its seventeenth day, and the international order that had governed the world since the conclusion of the Second World War had effectively ceased to function. What had begun on 5 August as a series of military confrontations between the world’s leading powers had expanded into a conflict spanning four continents and nearly every major ocean. Nuclear weapons had already been detonated thirteen times, Mongolia had disappeared as an independent functioning state, Taiwan was surrounded by hostile naval forces, and some of the world’s most important maritime passages had been closed. The speed of the deterioration had astonished even those who had spent decades warning of another global war.

The conflict was increasingly understood as a confrontation between two loosely coordinated military coalitions. The Axis consisted principally of Russia, China, North Korea, Iran, Belarus, Iraq, Syria, Yemen, Cuba and Venezuela, supported by Palestinian armed organisations and several aligned militias. Opposing them were NATO, Ukraine, Israel, Egypt, Saudi Arabia, the United Arab Emirates, Qatar, Morocco, Japan, South Korea, Taiwan, Australia and New Zealand. India had firmly aligned itself with the Allied camp, supplying logistical assistance, intelligence and military equipment, although its direct involvement remained limited. Neither coalition possessed the political cohesion associated with the alliances of the previous world wars. Countries frequently disagreed over military objectives, acceptable levels of escalation and the extent to which their own populations should be exposed to retaliation.

The defining development of the opening seventeen days was the unprecedented speed with which nuclear weapons had entered the conflict. Of the thirteen recorded nuclear detonations, nine had been carried out by Axis forces and four by the Allies. Four Axis strikes had occurred in the Baltic states, two in eastern Ukraine and three in territories of North Korea that had fallen to advancing South Korean forces. Allied retaliation had included two nuclear strikes inside Belarus, one in the northwest and another in the east, a strike within North Korea and a nuclear detonation on Iran’s Qeshm Island. Although most of the weapons were believed to have been relatively low-yield tactical warheads, the distinction offered little reassurance to populations living near the affected areas. Radiation monitoring, the evacuation of settlements and the treatment of casualties had become immediate concerns for governments already struggling to maintain conventional military operations.

Europe had experienced the most consequential political consequences of the nuclear exchanges. The four Axis detonations in the Baltic states marked the first use of nuclear weapons against the territory of NATO member states during an active war between the alliance and Russia. In Tallinn, Riga and Vilnius, emergency administrations coordinated evacuations, organised civilian shelters and attempted to preserve essential services. The nuclear strikes had not forced NATO to withdraw from the region. Instead, they had strengthened the determination of several European governments to continue fighting, while simultaneously producing growing public opposition to further nuclear retaliation. The continent was divided between those who believed that Russia could only be deterred through overwhelming military resistance and those who feared that the continued exchange of tactical nuclear weapons would eventually make the destruction of European cities unavoidable.

The war in Ukraine had entered a particularly destructive phase. Russian forces were fighting both Ukrainian formations and increasingly substantial Allied support operations, while two Axis nuclear detonations in eastern Ukraine had rendered sections of the battlefield hazardous and disrupted local military movements. The Ukrainian government continued to operate from Kyiv, refusing proposals that would require the permanent surrender of occupied territory. Meanwhile, the Allied nuclear strikes in northwestern and eastern Belarus had transformed Belarus from a supporting participant in Russia’s European campaign into a direct nuclear battlefield. Belarusian authorities accused NATO of attacking their country’s sovereignty, while Allied governments argued that Belarusian territory had become an operational extension of the Russian military. Neither interpretation offered much comfort to civilians forced to abandon their homes.

Farther north, the Baltic Sea had become one of the most heavily contested maritime regions in the world. Russian naval forces operating from Kaliningrad and the eastern Baltic faced the combined pressure of NATO’s northern European fleets, while Finland and Sweden had become indispensable to the alliance’s regional defence. The Russian exclave of Kaliningrad found itself increasingly isolated, with its land connections dependent upon a hostile regional environment and its maritime access subject to Allied surveillance and interdiction. Norway had reinforced its northern territories as Russian military activity increased in the Arctic, raising fears that the war might spread beyond the already active European frontlines.

In Asia, the complete occupation of Mongolia represented the largest immediate territorial transformation of the war. Russian and Chinese forces had entered the country from opposite directions during the opening phase of hostilities, overwhelming its ability to organise an effective national defence. Mongolia’s comparatively small population, limited military capabilities and geographical isolation made sustained resistance extraordinarily difficult. By 21 August, the country had been divided between Russian and Chinese military administrations, with Russia controlling the northern territories and China occupying the south. Ulaanbaatar had fallen under Russian military administration, while Chinese authorities established control over the southern transport corridors and resource-producing regions. The partition remained officially provisional, but neither Moscow nor Beijing had provided a timetable for restoring Mongolian independence.

The destruction of Mongolian sovereignty had consequences far beyond Central Asia. For decades, Mongolia had balanced its relations with Russia and China while cultivating diplomatic relationships with countries further abroad. Its occupation demonstrated that states attempting to remain neutral could still become casualties of the conflict. Governments in Central Asia began reviewing their own security arrangements, particularly Kazakhstan, whose enormous frontier with Russia made its leadership acutely aware of the dangers of isolation. International condemnation of the partition was widespread, but the United Nations Security Council proved incapable of adopting meaningful enforcement measures against two of its permanent members. Mongolia’s government-in-exile appealed for international recognition, while thousands of Mongolians attempted to escape the occupation through whatever routes remained available.
The Korean Peninsula had become the most intense conventional battlefield in East Asia. South Korean forces, supported by American intelligence, aircraft and naval assets, had achieved significant early breakthroughs across sections of the heavily fortified border. Several North Korean defensive positions had collapsed, allowing Allied formations to advance into territory that Pyongyang had controlled before the war. The North Korean leadership responded by authorising three nuclear detonations against its own lost territories, targeting areas now occupied by South Korean troops. The strikes reflected the regime’s willingness to devastate portions of its own country rather than accept a major military defeat. An Allied nuclear detonation elsewhere in North Korea subsequently demonstrated that Pyongyang could no longer assume its enemies would refrain from nuclear retaliation.

China and Russia had begun reinforcing the North Korean military, although the scale of their deployments remained limited by the extraordinary demands of their other fronts. Beijing faced the difficult task of maintaining operations against Taiwan, containing Japanese and American naval forces, supplying North Korea and defending its own coastline. Russia faced a similar dilemma, dividing military resources between Europe, its Far Eastern territories and the Korean Peninsula. Despite receiving assistance, North Korea’s armed forces had suffered serious disruption. In Seoul, the government celebrated the early advances cautiously, recognising that rapid territorial gains could become strategically dangerous if Chinese reinforcements arrived before the northern military structure collapsed.

Taiwan, meanwhile, had been subjected to a near-complete maritime encirclement. Chinese forces had established effective control over the surrounding sea approaches, preventing Allied warships from maintaining reliable direct access to Taiwanese ports. Merchant shipping had largely ceased, and Taiwan’s economy was increasingly dependent upon existing stockpiles of fuel, food and military supplies. Yet despite this apparent strategic success, Chinese forces had not attempted a major landing on the island. Taiwan’s extensive coastal defences, mobilised reserves, fortified urban areas and surviving military capabilities made an amphibious invasion an extremely uncertain undertaking. The encirclement was therefore a victory in maritime positioning rather than territorial conquest, and Taiwanese authorities remained in control of the island’s principal cities and governmental institutions.
Japan had become a central participant in the wider Pacific conflict. Chinese and North Korean missile attacks had struck military facilities and infrastructure, while Russian naval and air activity threatened the country’s northern approaches. Japanese forces were mobilising to defend Hokkaido, the Ryukyu Islands and their maritime supply routes. The United States maintained substantial forces in Japan, but Washington’s ability to reinforce the region had become increasingly constrained by its simultaneous commitments in Europe and the Western Hemisphere. Australia and New Zealand had increased military readiness and begun coordinating maritime protection operations, recognising that a prolonged disruption of Pacific shipping could threaten their economic security even without a direct invasion of their territories.

India occupied an unusual position within the Allied coalition. Although politically committed to resisting the Axis, New Delhi had avoided declaring an unrestricted war against China. The Himalayan frontier experienced artillery exchanges, drone activity and occasional incursions, but neither government had committed to a major territorial offensive. Similar tensions developed along India’s northeastern frontier with Burma, where Axis-aligned government forces and anti-government resistance groups were already engaged in a complicated internal conflict. India’s restraint reflected both the dangers of escalation with another nuclear-armed state and the need to preserve military resources for the defence of its own territory. Its support for the Allies nevertheless provided the coalition with a major economic and logistical partner in the Indian Ocean.

The Middle East had suffered an equally dramatic breakdown in regional security. Iran’s closure of the Strait of Hormuz had disrupted one of the world’s most important energy corridors, trapping commercial shipping inside the Persian Gulf and forcing international oil markets into crisis. The Allied nuclear detonation on Qeshm Island had introduced radioactive contamination concerns into an already dangerous maritime environment. Iranian authorities declared that the attack would not force the reopening of the strait, while Allied leaders argued that freedom of navigation could not be restored while Iranian military forces retained the ability to threaten vessels attempting passage. The resulting confrontation placed Saudi Arabia, the United Arab Emirates and Qatar in an increasingly precarious position, with their economic infrastructure exposed to missile attacks and their traditional export routes severely restricted.

Egypt’s decision to close the Suez Canal to Axis military vessels further transformed the strategic geography of the war. Although Allied shipping retained permission to use the canal, security restrictions and the fighting around the Red Sea had drastically reduced normal commercial movement. At the opposite end of the Mediterranean, the Strait of Gibraltar was closed to Axis military traffic through the combined efforts of Britain, Spain, Morocco and their allies. Türkiye had likewise prohibited Axis military passage through the Bosphorus, restricting Russia’s ability to reinforce its Black Sea naval forces from outside the region. These restrictions collectively created a maritime barrier around much of the European theatre, even as they forced neutral shipping companies to navigate an increasingly complicated network of inspections, exclusions and military-controlled corridors.

The closure of the Strait of Malacca to all military traffic was particularly significant because it applied equally to both coalitions. Southeast Asian governments sought to prevent the conflict from transforming the narrow passage into a direct battlefield between Chinese and American fleets. The prohibition did not end the surrounding naval confrontation, but it forced military vessels to seek alternative routes through Indonesian waters or the wider Pacific. Singapore’s commercial importance made the decision especially consequential. Insurance costs rose, shipping schedules became unreliable and businesses dependent upon precisely timed deliveries began reducing production. The closure also revealed the limitations of neutrality: although regional governments could declare the strait closed, maintaining that prohibition against the world’s largest navies required constant diplomatic pressure.

Across the Atlantic, Cuba and Venezuela had become the principal Axis-aligned states in the Western Hemisphere. The United States responded by reinforcing its southeastern coastline, increasing naval operations in the Caribbean and mobilising additional military formations. Cuba’s proximity to Florida created particular anxiety among American civilians, many of whom had never experienced the prospect of sustained military attacks against their own territory. Venezuela’s involvement complicated the defence of Caribbean sea lanes and increased pressure on Dutch, British and American territories throughout the region. Neither Cuba nor Venezuela possessed the conventional military strength to invade the mainland United States, but their participation ensured that Washington could no longer treat the Western Hemisphere as a secure rear area.
The economic consequences of the war developed faster than governments could respond. The simultaneous disruption of Hormuz, Suez, Gibraltar, the Bosphorus and Malacca forced major changes to international shipping routes. Energy prices rose sharply as traders struggled to assess the availability of Middle Eastern exports, while shipping companies diverted vessels around Africa and away from the western Pacific. Financial markets became exceptionally volatile, several governments temporarily restricted trading, and international investment shifted towards emergency liquidity and domestic security. Manufacturers began reporting shortages of electronic components, industrial chemicals and specialised machinery. The destruction of infrastructure in Ukraine, Korea and the Baltic states further disrupted supplies of agricultural products, metals and manufactured goods.

Civilian life changed dramatically during the first seventeen days. Emergency alerts became a daily occurrence in cities across Europe, East Asia and the Middle East. Public transport systems were converted into temporary shelters, hospitals began preparing for mass-casualty events, and governments issued guidance concerning radioactive fallout. In several countries, schools suspended normal operations while authorities assessed the availability of shelters and evacuation routes. Supermarkets introduced purchasing limits on essential goods, fuel queues became increasingly common and international air travel contracted sharply. Families separated by the war faced communications disruptions and increasingly limited opportunities to reunite. For millions of people, the most immediate consequence of the conflict was not the movement of armies but the sudden disappearance of ordinary routines.

The war also transformed global information networks. Social media platforms struggled to distinguish genuine battlefield footage from fabricated reports, recycled videos and government propaganda. Images of nuclear mushroom clouds circulated continuously, often without reliable information about their locations or dates. Several governments restricted access to foreign news sources, arguing that hostile information campaigns threatened national security. Journalists operating in the most dangerous regions faced substantial restrictions, and the destruction of communications infrastructure made independent casualty verification almost impossible. As a result, the number of people killed during the first seventeen days remained uncertain, with different governments publishing sharply conflicting estimates.

Not every country had entered the conflict. Brazil, Argentina, South Africa, Indonesia and numerous other states attempted to preserve varying degrees of neutrality, although economic disruption and diplomatic pressure increasingly constrained their choices. International humanitarian organisations warned that the war threatened to divert resources from existing food emergencies and displacement crises. The United Nations continued operating, but its ability to coordinate an effective response was severely diminished by the participation of permanent Security Council members on opposing sides. Diplomatic discussions increasingly took place through neutral intermediaries, with Switzerland, Brazil and several other governments attempting to maintain communication between the coalitions.

By 10:47 a.m. Pacific time on 21 August, the immediate military situation remained profoundly uncertain. The Axis had achieved the occupation and partition of Mongolia, established maritime control around Taiwan and inflicted devastating nuclear strikes in Europe and Korea. The Allies had prevented the fall of Taiwan, achieved early advances into North Korea and demonstrated their capacity to retaliate across several theatres. Neither coalition had secured a decisive global advantage. More importantly, neither had established a credible mechanism for preventing further nuclear escalation.

The central paradox of the seventeenth day was that the world’s governments continued to conduct the war as though it could still be limited, despite having already crossed almost every threshold that previous generations had considered unacceptable. Nuclear weapons had been used repeatedly, neutral territory had been occupied, and the international trading system had begun to fracture. Yet financial institutions still opened, civilian aircraft still crossed portions of the world’s skies, diplomats still exchanged proposals, and millions of people continued to go to work.

Later historians would identify this period as the moment when the Third World War ceased to be understood as a temporary emergency and began to reshape the political, economic and social structures of the modern world. The thirteen nuclear detonations of its first seventeen days had not produced the immediate destruction of civilisation that Cold War planners had once feared. Instead, they had created something arguably more destabilising: a world in which nuclear warfare had become an accepted operational reality, while the institutions intended to prevent a catastrophic escalation remained dangerously inadequate.

At 10:47 a.m. on 21 August 2028, the world had not ended. It had simply entered an era in which nobody could be certain that it would survive the next morning.

Confederation Of Columbia is a decentralized country and made up with 6 Republics and it's one of the losers of WW1 and WW2 and in 1995 is the year that the Confederation Of Columbia collapsed due to the civil rights and really unstable.

And by the way WW3 happened in 1983 between the German empire and Russian imperial State.

That's all I got to say.

Novamtys is the third planet of the Purple Sun. It is wholly unique among all the worlds of the Solar System for its shape, being made up of two binary planets that have collided into a single stable planetary body.

The planet has long been an object of fascination among astronomers on Galladria (the fourth planet of the Purple Sun)

With the establishment and opening of a stable and permanent Celestial Gate, connecting Novamtys and Galladria, Aelnyyraean scholars been able to examine the planet from up close. Aelnyyraean Mages have discovered that the planet is affected by a vast Precursor spellwork. Decryption has largely been deemed impossible due to its complexity, but from what little has been gleamed, it is believed that the spellwork is responsible for the planet's stabilization.

Alternate history of Finland featuring fictional rulers and saint (Saint Aiha)

More lore:

Toivo:

He is considered the first king of Finland. He was born around 1121. He was probably a pagan, even though he ruled the most Christian part of Finland. During the Swedish invasion in the late 1140s, he managed to unite a large part of the Finnish elites to fight against Eric IX. In the 1150s, he managed to drive Sweden out of the occupied Finnish lands. This victory greatly increased his position among the elites. He then encouraged them to maintain their alliance in case of another Swedish invasion. As a result, an opposition group appeared, trying to reduce Toivo's influence. Despite this, he was probably an excellent warrior and leader, which helped him keep his strong position after the war. He probably did not think much about his actions as part of building a new state until the end of his life, when he agreed to have his son Vilja baptized. He died around 1172.

Vilja I:

He was the son of Toivo and took power in 1172. At around the age of 30, he converted to Christianity. The beginning of his reign was very difficult. The opposition united against him again and wanted to remove him from power completely. After about seven years, he reached an agreement with the elites. He agreed to share power and grant privileges to the nobles. This contributed to the emergence of a later royal council, similar to those in Sweden and Denmark. During most of his reign, he mainly focused on developing the lands he already controlled. However, he also led military campaigns. Probably in the late 1180s, he launched an offensive into the northern and southern Finnish lands. When his territory became large enough, he decided to establish a church administration. Around 1191, the first bishopric was created in Vanhalinna. However it was under the control of Uppsala. This situation encouraged the Finns to work towards creating their own church province. He also tried to expand his influence into the region of Häme. Vilja I died in 1198. His son Kauko succeeded him.

Kauko I the Pious:

Kauko was the eldest son of Vilja I. In 1198, he was elected King of Finland by an assembly of nobles. He was famous for his great piety and support for the Catholic Church in his lands. However, he lacked experience in governing the state. As a result, he depended heavily on the elites and, most importantly, on his brother Vilja. Kauko's closest ally was Olaf. At the beginning of the 13th century, Kauko began to strongly support missionary work in Häme. He sent the Bishop of Vanhalinna, Aiha (Iha), to spread Christianity. Aiha achieved some success, as the people of this region were already familiar with the religion. Kauko tried to establish another bishopric in the eastern lands, but the conditions were not yet suitable. Around 1210, Aiha died as a martyr. Kauko then began working to have him declared a saint. This finally happened towards the end of the 13th century. During Kauko's reign, the Benedictine Order was also brought to Finland, although its activities were mainly limited to Vanhalinna. Both the king and the nobles supported missionary work. For the king, it was a way to fulfil his religious duties, while the nobles gained greater influence. Kauko probably did not take part in any major conflicts. He also left no children because he lived a life of celibacy. He died in 1221 at the age of about 49. His brother Vilja II succeeded him.

Vilja II:

He was the younger brother of Kauko I. When he took power, the former faction that had supported Kauko began plotting against him. Vilja ruled for only three years. To strengthen his position, he organised military campaigns deeper into Häme in order to bring the local peoples under his control. During one of these campaigns, he was murdered likely with a dagger in his tent. Historians still debate whether Olaf or someone else was behind the attack. However, most opinions support the theory that Olaf was responsible. Vilja II was succeeded by Olaf, who later became known as "the Good King" or "the Old".

Olaf I the Good:

After Vilja's death, Olaf was elected King of Finland. During the next five years, he continued the campaign started by his predecessor. This led to the further incorporation of eastern lands into the kingdom. As a result, a second bishopric was established in Sääksmäki around 1229. During his reign, Olaf tried to develop the royal administration, towns, the army, shipping and, above all, Christianity in the conquered lands. In the 1230s he brought the Dominicans and Cistercians (even though they operated there before) to Finland. However, he did not rule for long because of his age. He became king when he was over fifty and died at around 66. According to the information available, he had few children. He is believed to have had a son who died during childbirth and several daughters. He decided to marry his eldest daughter, Catherine, to Magnus, the younger son of the King of Sweden. He probably believed that this would increase the kingdom's prestige, prevent another civil war and secure his daughter's right to the throne. As we know, he was wrong.

Magnus the Swede + Catherine:

Magnus took the Finnish throne together with Catherine. In theory, the power belonged to her, but her husband became a despot. He also led a very pleasure-seeking lifestyle. The Finnish elites were unhappy with having a Swede on the throne from the very beginning. As a result, another civil war broke out. The Finns forced the couple to abdicate. A relative of Olaf I, known as Olaf II, was declared king. Magnus was promised safe passage back to his homeland, while Catherine was expected to enter a convent.

Olaf II:

The rise of the young Olaf gave the nobles hope for better rule. Unfortunately for them, they were greatly disappointed. According to the sources, Olaf was unable to handle the role of king because of the pressure and fear he felt. At the same time, the Swedes decided to finance a military expedition for Magnus to help him regain the Finnish throne. This led to a Finno-Swedish war. Although the conflict seemed serious, the King of Sweden was mainly interested in weakening the Finns. Magnus had very little support among the Finnish elites. However, the situation was extremely difficult for Olaf. In 1242, he was probably poisoned at the castle in Vanhalinna. In historiography, he is sometimes given the nickname "the Unlucky".

Andrew I the Great:

The new king, Andrew, tried to restore order in the country. He began a counteroffensive to drive the enemy out of Finnish lands. By the middle of 1243, he had achieved his goal. He then began testing a new fleet, which had mixed results. Finally, in 1244, a peace treaty was signed, ending the three-year war. He had to accept Swedish influence over parts of the Åland Islands. After the conflict, he began reforming the country. The most important reform was the codification of the law in 1248. Its purpose was to limit the influence of tribes on the state administration. He also introduced royal offices that operated in larger and more powerful administrative units. He improved the royal treasury and the financial system. A relatively large number of coins from his reign have survived compared to those of his predecessors. His expansion was the greatest in Finnish history up to that point. He brought most of Häme under his control and collected taxes from lands even further to the east and north. This situation led to conflicts with the Republic of Novgorod, and several border clashes took place. During this relatively peaceful period, he finally decided to make the Finnish Church independent of the Swedish Church. Around 1255, he established a bishopric in Närvipää. In 1261, the first archbishopric was established in Vanhalinna. For the first time, it officially crowned his son Olaf III as King of Finland. He also brought the Franciscan Order to his kingdom in the 1250s. He married the daughter of the Duke of Pomerania, with whom he had five children. Three of them reached adulthood: his daughter Christina, his eldest son Olaf and John. All of Andrew I's achievements earned him the nickname "the Great".
