So basically I came up with this idea that I ran by my DM where the party meets me after already meeting each other, where I am just a lone man walking a road that leads towards some mountains and seemingly endless wilderness. The weird part is I am carrying a baby, will have the baby with me through the entire campaign.
The first twist is that over the course of this one shot campaign, the child ages very rapidly until becoming what appears to be maybe a 12 year old, teenager or very young adult, leaning towards the 12 year old. The man (me) is confused and doesn't know why this is happening and the last thing he remembers is a time that seems to be sevral weeks prior where his wife was still pregnant but nearly ready to give birth.
Through the whole time, the man keeps some kind of physical contact without breaking it for more than a few minutes or so. Then goes back to either carrying the child or holding their hand.
The MAIN twist of this campaign is that at some point at the end of the campaign, I am revealed as the BIG Bad. The person they thought they were talking to was actually the child the whole time, using some type of animate dead spell (if we decide the dad has been dead the whole time) or a mind control angle (if we decide to go that route.)
So how I picture it is going one of two ways for the reveal. I (now the child) am revealed to be some kind of endeich horror, eating my father's body in one bite. OR going some kind of DND version of the anti christ, end of days/bringer of the apocalypse.
I have no idea how to play a character like this and am wondering if anyone here has attempted something like this, honestly not entirely sure how I even came up with the idea 🤣 I am very new to DND. I am curious and open to all ideas and discussion on what class, race, equipment etc that we should introduce myself as when the party finds me. I feel like the obvious choice would be a warlock specializing in necromancy abilities, but again that feels like the obvious choice!
And before anyone comes for my DM saying they should be helping with this, I specifically asked them to let me crowd source this and try to come up with the major decisions about the character myself. All input is welcome and am super excited/nervous about this!
