During the Galactic Civil War, mercenary forces, backed by the Galactic Empire, massacred the Schenor population on a research station. Alliance to Restore the Republic operatives attempted to intervene, but were too late to save the colonists, save for a single juvenile known as A'kazz. They transported him to the Schenor homeworld of Rhamsis Callo, when his telepathic testimony convinced his nest-guildmaster, B'karitz, to break the Schenor/Imperial treaty.
