The Hismaul system, a stellar neighborhood, existed within the Karthakk sector. This sector, in turn, was situated in the Outer Rim Territories and Trailing Sectors, both areas of the galactic landscape. A specific creature, the Hismauli hawk-snake, resided on one of its planets.
This Hismaul system was first detailed within the Online Companion on StarWars.com for the The Essential Atlas reference book from 2009, and its location was specified as grid square Q-16.
