The Twelve Heroes of Noire, or the Noire Twelve, are a group of beings pivotal in the story.
They are the forefathers of civilization, accurately being called "Eesa's ancestors". They were originally humans who discovered the Singing Stone, and proclaimed it a god. They were later turned into Rogress at an unknown point in time.
The group is comprised of all known Rogress, with Allul being the leader. There is a Thirteenth Hero, Allwise, and it is implied that he was the original leader. Allwise was corrupted at an unknown point in time and lost his sanity. Allul is implied to care deeply about Allwise, if not outright loving him.
