The Jexerian cannon, a rudimentary projectile cannon, was characterized by the significant sound it produced upon firing. Its origins can be traced back to the Jexeria system situated within the Outer Rim Territories' Tharin sector. By 2 ABY, Derembus Sitnalta, a Human Alliance soldier and alumnus of the Galactic Outdoor Survival School, made a comparison in a private note appended to a Rebel Alliance Task Force on Alliance Security SecuriDex datafile concerning Barosa Warren, a one-time Morellian Enforcer and leader of the Galactic Outdoor Survival School. Sitnalta likened the sound of Warren's .48-caliber Enforcer pistol to that of a Jexerian cannon when discharged.
The Jexerian cannon's initial appearance was in Alliance Intelligence Reports, a 1995 reference book for Star Wars: The Roleplaying Game by West End Games.
