This is specifically about changing a character's ancestry due to Transmigrate.
The adventure itself doesn't quite specify if the PCs are aware of the fact that the rank 5 Transmigrate ritual can change their ancestry. (As far as I could find at least)
Is that knowledge supposed to be purely meta for the players or would it be okay for the entire town to know this in-character? And additionally, would it be okay for certain NPCs to actively choose their new ancestry? (Perhaps through some additional magic?)
This would only effect 2 NPCs in my town:
- So-Jin, who is forlorn in my adventure and is simply tired of watching all her loved ones die. She'd wanna become some shorter-lived ancestry and age like everyone else.
- The adoptive sister of one of the PCs, who is secretly a jorogumo (only her family knows) and secretly the daughter of Ren Mei Li (only RML knows this so far, but it'll be revealed during book 3). The sister doesn't want to be a jorogumo princess and would want to become anything else, in an effort to hide from RML.
Would it be okay for them to actively do this, or should it rather be handled as some kind of fateful luck that made these NPCs reincarnate as something they wish for?
