before i pitch veritatem, lemme just say your un is giving me all the magicians feels. i'd love his older brother (a christian bale pb would be ace but totally open to anyone!) who's now a ghost or lich that has a newly complicated relationship with this guy since he's kinda responsible for his current state. additionally an immortal who swears this guy is the reincarnated version of someone they were close to because of how identical they look.
