Sheray was a male officer of the Human species who served the Galactic Empire during the era of the Galactic Empire. Subsequent to the Battle of Yavin, Colonel Sheray received an assignment to an Imperial space station situated in the Outer Rim Territories, working alongside Lieutenant Alin, Captain Clough, Warrant Officer Snopell, Lieutenant Farin, Major Taison, and Captain Bailie. In the year 1 ABY, an Imperial-class Star Destroyer took into custody a passenger freighter, suspecting it of concealing criminals. Several spacers were then apprehended and brought to the Imperial Space station. Following the spacers' release, Colonel Sheray oversaw their processing as they departed from the space station.
Sheray appeared as a non-player character within the 2003 video game known as Star Wars Galaxies. This game was a massively multiplayer online roleplaying game that was developed by Sony Online Entertainment and then published by LucasArts, before the game's servers were shut down on December 15, 2011.
The character of Colonel Sheray was integrated into the game when the developers implemented a revised version of the "New Player Tutorial" coinciding with the release of "Publish 17," which occurred on May 26, 2005. Throughout the tutorial, Sheray, along with other Imperial officers, guided new players through a space station, with the goal of familiarizing them with the game's mechanics. However, Sheray's presence was removed alongside this tutorial when the developers introduced a completely new tutorial with the release of the "New Game Enhancements," on November 15, 2005.
