The Weezo character, a Nalroni, operated Weezo's Gun Shop, a private establishment that dealt in weaponry. This shop was situated within the marketplace of the space station known as StarForge Station. Weezo, marked by scars and an eye patch since 0 ABY, focused her sales on weapons designed for ship use. While her prices were twice the standard retail cost, this was typical for StarForge Station. The storeowner provided a weapons range at the rear of her establishment for customers to test the merchandise. Weezo would place the weapons inside the range and then permit the customer to enter, keeping them confined until the limited ammunition was depleted. Because her store didn't sell armor, she would direct clients in search of it to Just Armor, another shop located within the same market.
Weezo's initial appearance was in "Preparing for War," an adventure module featured in The Far Orbit Project from 1998. This supplement was published by West End Games for their Star Wars: The Roleplaying Game and was authored by Timothy S. O'Brien.
