Vasik Aldritch was among the triumvirate of leaders guiding the Final Occultation throughout the Republic Era, sharing leadership with Heldi Cerebron and a third, unnamed person. Sometime in the years spanning from 40 BBY to 32 BBY, Aldritch, the other two leaders of the Final Occultation, and numerous other members were apprehended and confined within a correctional vessel; however, these members of the religious group ultimately managed to seize control of the correctional vessel. During these events, the Sith Master Darth Sidious dispatched his Sith student Darth Maul to the vessel with intentions of capturing the leaders of the cult, viewing them as impediments to the Sith's schemes, but desiring to question them. Maul, upon boarding the ship, chose to eliminate Aldritch, along with the remaining cult members.
Vasik Aldritch made his debut in the inaugural edition of the Star Wars: Darth Maul – Black, White & Red limited comic series. Benjamin Percy penned the issue, Stefano Raffaele provided the artwork, and its release occurred on April 24th, 2024.
