Darth Drear was a male Sith Lord who served the Sith Empire and later reigned as a Dark Lord of the around 4,645 BBY. He founded a Sith academy on the planet Odacer-Faustin and worked his students to death as they labored in the construction of the academy. Beneath the academy library, Drear built a temple, where he practiced Sith alchemy and searched for a pathway to immortality. He developed an elixir to fulfill his goal, effectively creating a disease that turned all those infected into zombies, knowledge he recorded into a holocron. Before Drear could successfully implement the final stage of his project, however, he succumbed to the effects of the disease and—to the knowledge of later Sith at the academy—died.
