Redeemed, akin to redemption, is the process of being pulled back from darkness and turned back to neutrality or good. These days, the process usually involves divine quests or great deeds.
In the God Era, a labyrinth called Reconstruction was used to turn one back from evil. Giracian, once a servant of the Demon Lord Sess'innek was redeemed at this place; she would go on to become a Higher Power for good and the forces of neutrality.
In more recent times, Sakazrân Garbanâth is the most well-known for having been successfully redeemed.
