Wens Aleusis functioned as a Jedi Master within the Jedi Order, holding a seat on the esteemed Jedi High Council during the tense Cold War that occurred between the Galactic Republic and its adversary, the Sith Empire. His fellow Jedi regarded Aleusis as pensive and somber. In the year 3643 BBY, the Jedi Master participated in a Council meeting through a holoprojector, during which the Council collectively determined that Shigar Konshi, who was the Padawan under the tutelage of the Order's Grand Master Satele Shan, was prepared to undertake the rigorous Jedi Trials.
The character of Wens Aleusis made an appearance in the 2010 novel titled The Old Republic: Fatal Alliance. This novel, penned by Sean Williams, served as a promotional tie-in for the 2011 video game Star Wars: The Old Republic, which was developed by BioWare. Similar to numerous other characters introduced in the novel—which was conceived early in the game's production—Aleusis has not been featured in any other facets of the game's expansive multimedia project.
