SaGa 3: Jikuu no Hasha - Shadow or Light
In the DS remake, the events of the story are the same, with the exception of the true ending where Borgin is the true final boss. Borgin reveals to the party he is the same entity as Steslosman, and that he masterminded everything to get them to destroy both Xagor and Sol, because to destroy one and not the other would create an imbalance. Borgin tried to eliminate the threat of Xagor many times before, and once led Jupiah and Faye on an expedition to Pureland, but he was afraid they would both destroy Xagor before he fused with Sol. Borgin then told Fenrir about Faye, resulting in her kidnapping and allowing Borgin to stab Jupiah in the back. Borgin also fixed the Talon so it could only travel between three specific time zones. The party confront Borgin, who takes the form of the 'Wanderer'. After being defeated, he leaves the party and vanishes.
