Selsor was a terrestrial astronomical object located in the Selsor system, a part of the Zarracina sector in the Trailing Sectors portion of the Expansion Region. It featured several continents.
At some point during the reign of the Galactic Empire, the Imperial cold assault stormtrooper unit known as the Snow Hawks conducted a successful winter campaign in the frozen terrain on Selsor's primary continent.
Behind the scenes
Selsor was introduced in Rules of Engagement: The Rebel SpecForce Handbook, a 1997 West End Games sourcebook authored by Timothy S. O'Brien for use with Star Wars: The Roleplaying Game. The 2009 reference book The Essential Atlas placed the Selsor system, and therefore the celestial body Selsor, in grid square O-14.
