Eadie

Beware, brainstorming below:

Eadie is much more likely to end up running with gangs, raiders, or cults due to her peacekeeping nature. So, small past
She was part of Vault 76 (i have yet to decide if she was prewar or vault born. Cus the age for PCs in that series is like 0-25 and 45-???)
She joined the cult of Mothman but ended up trying to preach against the main preachers and ended up being labeled as a false prophet. She ended up becoming a ghoul when the other vault residents decided to nuke Appalachia to hell to stop a disease from spreading. She is more or less the only survivor in that region.
This has caused 2 major ideals in her, the strong belief in the supernatural and the fact that war and mass genocide is usually not the answer (she counts undesirables like ferals, raiders, and mutants in this). She doesn't want to see another nuclear style war taking place and is able to see it a lot in the commonwealth. So, she will try to unite everyone, even the folks who might be the most vicious or cracked up. she believes that morals have no place when it comes to negotiations

she has trauma associated with underground spaces
being that she was trapped in a bunker for weeks surviving only on acid rain that was slowly cooking her from the inside out then, after finally digging her way out, realized that the only thing left of life were shadows on rare brick walls that still existed
cus, guess what fallout 76, 20 NUKES A DAY WILL FUCKIN DO THAT TO YOU

I kinda ended up making Eadie a big animal loving person. but not the vegan kind the "we should eat the pests instead of the 'prime meat'" and then casually promotes cannibalism
