His name is "B", sitll does not have an actual name.
Basically he died cuz a betray and got resurrected by a corrupted aspect, replacing the part of his body lost. Now seeks revenge n shit, also wants to try to live his life they took from him.
PD: The aspect also punishes "B" as a payment of resurrecting him (like side quests, or just putting him on a 9h minimun waged office workplace for months)
