Kollan Xa, an Advozse of the male persuasion, functioned as a representative for the Ccalras Corporation within Mos Eisley around the period of the Battle of Yavin. His attire consisted of vibrantly red garments.
Kov Du Derra, a Duros, served as his protector.
During his tenure with Ccalras, he and Kov abducted Eila, the romantic partner of Beeyon Nace, to facilitate negotiation processes. Furthermore, he maintained a chamber at the establishment known as the Lucky Despot.
A band of spacers, assisting Nace, pursued Du Derra and liberated Eila. Nevertheless, they subsequently observed her aligning with Xa, Du Derra, and Klatooinian thugs in a scheme to deceive Nace into providing information about Mos Eisley customs patrols.
Kollan Xa makes an appearance in the 1997 Mos Eisley Adventure Set by West End Games.
The book proposes, as a segment of the adventure's resolution, that the player characters manage to successfully expel Xa and the thugs.
