Since the LN translations have stalled there's 2 confirmed in the MCs timeline. In the alternate game original story before MC reincarnates...he has a child with his wolf slave. He was loved by all of his clan but dies "alone" because he didn't want his people suffering/dying when the heroes aim was his life alone so he sent them into hiding while soloing the whole army. After his death,  his wife leaves there child with the female aristocrat that also likes him & single handedly annihilates the kingdoms army plus slaughters all of the heroes party.

original Arc was basically the same as the MC but Arcs story was never really expanded on since he's not the Hero. It'll show you glimpses later on about Arcs (game version) struggles to protect those close to him while continuing to solo all the dangers til hi eventual death.
