Illyria's killers were Old Ones who killed Illyria and trapped her sarcophagus in the Deeper Well. They sealed part of her energy into her symbols and hid them so that she would not find them. They forgave Catari's life but on the conditions that he never surrendered one of the scythes where the energy was sealed.
Behind the Scenes
As they appeared only in a crossover, their canonicity is unknown. Unlike all other characters whose only Buffyverse appearance was in Fallen Angel: Reborn, Illyria's killers are often considered part of the IDW Angel continuity.
