Willoc served as a sergeant within the Royal Naboo Security Forces during the time of the Galactic Civil War. His assignment involved probing the Old war bunker, located near Kaadara, which had been seized by the Skaak Tippers. Tragically, Sergeant Willoc disappeared while undertaking this task, and later, a spacer discovered his comlink inside the bunker.
Willoc's initial appearance occurred in the 2003 video game Star Wars Galaxies, a massively multiplayer online roleplaying game. This game was created by Sony Online Entertainment and distributed by LucasArts, before it ceased operation on December 15, 2011. Willoc's inclusion in the game was part of the "Legacy Quest" feature, introduced with the release of "Publish 25", also known as the "New Game Enhancements," on November 15, 2005.
