Raskane IV, a planet situated within the Sepan sector, existed as an Expansion Region locale. Around 3643 BBY, political pressures almost sparked an internal conflict; however, someone involved with a side in the ongoing struggle between the Galactic Republic and the reconstituted Sith Empire diffused the precarious situation. During the Galactic Civil War, Rebel Alliance operative Matt Talon once professed to have caused the death and agony of an alien on Raskane IV.
Raskane IV was a planet of the terrestrial type. It held the fourth orbital position within the Raskane system, which itself was located in the Sepan sector of the Slice region of the Expansion Region.
In the vicinity of 3643 BBY, internal political tensions on Raskane IV nearly escalated to a civil war. To determine the faction that would be easiest to manipulate in the future, an individual associated with one of the sides in the ongoing struggle between the Galactic Republic and the reconstituted Sith Empire sent a companion to the planet. This companion was also charged with securing the success of the chosen faction. Ultimately, the companion skillfully reduced the political stress on Raskane IV, turning the resentment of the planet's political figures towards the most outspoken advocates for the civil war.
Matt Talon, an agent of the Rebel Alliance who operated undercover as a slaver and possessed a brutal nature and history, attempted to frighten someone during the Galactic Civil War. Talon claimed to have once inflicted trauma upon an alien on Raskane IV, with the victim dying after enduring agony for three days.
The first mention of Raskane IV occurred in Galaxy Guide 9: Fragments from the Rim, a 1993 sourcebook for West End Games' Star Wars: The Roleplaying Game, authored by Simon Smith and Eric S. Trautmann. The 2009 reference work The Essential Atlas placed the Raskane system, and consequently Raskane IV, within grid square P-13. The 2011 massively multiplayer online roleplaying game Star Wars: The Old Republic, developed by BioWare, introduced "Raskane Four" as an alternative designation for the planet.
