The Osskorn system, a star system, existed within the Tyan sector. This sector was situated in the galactic areas called the Mid Rim and the New Territories. A hyperlane provided connectivity between this system and the worlds of Tyan and Kwannot. By 12 ABY, it resided within the territory controlled by the New Republic. The well-known Osskorn Stout drink originated from this very system.
The reference book The Essential Atlas, which was published in 2009 and authored by Jason Fry together with Daniel Wallace, initially brought the Osskorn system to light, locating it in grid square L-6.
