The party meets Abyssion at Flanoir after unknowingly obtaining one of the Devil's Arms. Abyssion tells them the story about a man named Nebilim who sought to conquer Tethe'alla and the curse he left behind. As the last of a family of demon hunters cursed by Nebilim, he seeks to save his life by sealing the Devil's Arms away but is too weak to do so. The party volunteers to help, so he gives the party the Nebilim weapon and "Nebilim's Key" which allows them to open the chests that contain Devil's Arms. Abyssion promises to seal the Devil's Arms at the bottom level of the Temple of Darkness once gathered.
