Yawse Felsiy, a collector of objects, existed during the era of the Galactic Civil War as it is described in legends. Some time after the Battle of Yavin, Felsiy took up residence on the Tansarii Point Station, located within the Bright Jewel system. In the year 1 ABY, Yawse Felsiy tasked a certain spacer with the retrieval of dust durnis that had been scattered throughout the space station. Upon the successful completion of this assignment, Felsiy rewarded the spacer with a feather duster and encouraged them to explore the galaxy in search of items for collection.
Yawse Felsiy functioned as a non-player character within the 2003 video game entitled Star Wars Galaxies. This game was a massively multiplayer online roleplaying game that was created by Sony Online Entertainment and subsequently published by LucasArts, before the game's servers were shut down on December 15, 2011. Felsiy was integrated into the game with the release of "Chapter 8" on January 15, 2008.
Felsiy's visual appearance was subject to randomization with each server reset. The appearances that Felsiy could potentially have included, but were not limited to, male Aqualish, male Bith, female Twi'leks, and female Trandoshans.
