The Hismauli hawk-snake constituted a species that originated from the Hismaul system. Lando Calrissian, a skilled gambler by trade, once remarked that a Zeltron overseeing a brewery belonging to Calrissian on the planet of Clendor, possessed a temperament comparable to these snakes.
The initial reference to the Hismauli hawk-snake appeared in The Essential Guide to Warfare, published in 2012, a work authored by Jason Fry and Paul R. Urquhart and intended as a compendium detailing the wars within the Star Wars galaxy.
