Trebela

During the Galactic Civil War, Trebela was ruled by Governor Kraxith of the Galactic Empire. A major Rebel Alliance network operated in Trebela's capital at that time, and it was comprised of several Rebel groups that operated independently of each other, with no group being aware of the others' activities or identities. Kraxit eventually broke up the network, and his surprise at the extent of the organization was eclipsed by the incredulity of the involved Rebel agents themselves.

Trebela was first mentioned in the 1987 The Star Wars Sourcebook, which was authored by Bill Slavicsek and Curtis Smith and published by West End Games for use with Star Wars: The Roleplaying Game. "Twinkle, Twinkle Little Star, How I Wonder Where We Are," a 1990 roleplaying game source article published in Voyages SF 13, placed the Trebela system in a sector of the same name.

Since that article was released outside of the Lucas Licensing process, its canonicity within the Star Wars Legends continuity was never confirmed. The 2009 reference book The Essential Atlas subsequently placed the Trebela system, and therefore Trebela itself, in grid square O-13, and the StarWars.com Online Companion to the book further overrode the Voyages SF 13 placement by establishing that the Trebela system was part of the Altier sector.
