Jaek Vercet, a Human male, served as an officer within the ranks of the Galactic Empire during the era of the Galactic Civil War. Following the Battle of Yavin, Vercet took on the role of Imperial Representative for the city of Moenia, situated on the planet Naboo. During his time in Moenia, he frequented the local university. In the year 1 ABY, a Rebel informant approached the officer, expressing a desire to defect to the Empire. This individual was willing to share valuable intelligence in exchange for Imperial immunity. Consequently, Vercet enlisted an Imperial operative to escort the Rebel informant to Lieutenant Allard Lissara who was located at the Emperor's Retreat. However, the informant suffered an attack and sustained injuries. Incapable of movement, he instructed the Imperial operative to relay a specific codephrase to Lissara: "Wookiees walk at night in the trees of Naboo." The operative successfully delivered the designated codephrase.
Within the 2003 video game Star Wars Galaxies, Jaek Vercet existed as a non-player character. This massively multiplayer online roleplaying game was the product of development by Sony Online Entertainment, and was published by LucasArts. The game was eventually shut down on December 15, 2011.
