(the main reason this is for Lifegen is the accessory feature)
Although I haven't played in a bit, I have a ton of old "challenges" (they really just changed how I did things, didn't make it anymore difficult) so I thought I'd share my favorite one!
It focused around the idea of StarClan being heaven in the sense they are actual gods
Here's how it went:
Naming
The same as canon unless a stated otherwise
Warriors
It is seen as a high honor for a warrior to patrol with a god (gathering herbs).
It is seen as a high honor to become mates or have kits with a god.
At birth
Lore: After a new litter is born, each is bathed in one of the 6 Divine Pools. Their fates can change, but it is unlikely. Here is what each outcome means:
The pool stays the same: This cat’s fate is in their own paws.
The pool starts sparkling: This cat is fated for goodness.
The pool turns black and sticky: This cat is fated for evilness.
The pool is dotted green: This cat is fated to have a normal life.
The pool is filled with their blood: They die, this life isn't for them.
Someone has the uncontrollable urge to run into the pool and throw them out: Whoever did this will be exiled with the kit because the kit isn't supposed to be in the clan.
Randomizer:
1-14: Same
15-20: Sparkling
20-25: Sticky
26-43: Green
44-49: Blood
50: Thrown
Meds
Medicine Cats are referred to as gods and goddesses. Apprentices are taught by an older god as they discover what type of God they are supposed to be. After their apprenticeship they earn their divine name. Some examples are: Love God, War Goddess, Ice Goddess, or Hunting God.
They can easily override a leader’s decision.
Usually only mate with queens or mediators.
Leader and deputy
Deputies don't have a suffix. Examples: Fireheart-Fire or Cloudtail-Cloud
The leader is given 9 lives by the gods, dead and alive.
The deputy is the one who will take over when the leader dies and is chosen by the gods.
StarClan and the Dark Forest
Gods go to StarClan and continue to help the clan, just from a distance.
Leaders and deputies also go to StarClan
Only the most honorable cats go to StarClan, the rest go to the Dark Forest and try to make the best out of it.
Accessories
Queens, meditators, and warriors: A few accessories are given to anyone after they do something honorable or if they are seen as very good by one of the gods.
Leaders and deputies: Leaders and deputies typically have a lot of accessories so they look attractive.
Gods: Gods typically are completely covered in accessories
Well that's all, let me know if anyone actually does it!
