The Hasaq system resided within the Askarian sector. This sector was a component of the Slice region found within the larger Expansion Region. The system's placement was along the hyperlane called the Nanth'ri Route, connecting it with the Attahox, Circarpous, and Zaloriis systems. Its central star was an orange-hued sun. From 3959 BBY to 3956 BBY, the system belonged to the Sith Empire established by Dark Lord of the Sith Darth Revan.
The 2009 publication The Essential Atlas, penned by Daniel Wallace alongside Jason Fry, provided the initial reference to the Hasaq system, locating it in grid coordinate P-12.
