The Haseria system existed within the Haserian sector. This sector was situated in the Slice area of the Mid Rim. The Reena Trade Route provided a connection from this system to both the Monastery system and the Druckenwell system, the latter being located in the Doldur sector. The sentient Haserian species inhabited the Haseria system.
The reference book The Essential Atlas, published in 2009 and authored by Daniel Wallace and Jason Fry, marked the first appearance of the Haseria system, locating it within grid square P-15.
