Bardian Aelto held the position of a young chemist serving the Galactic Republic on Coruscant, the Republic's capital planet, during the period of the Cold War that existed between the Republic and the reconstituted Sith Empire. Before being tasked with analyzing planetary data to assess habitability, Aelto briefly contributed to several projects centered on the investigation of stimulants known as adrenals. One evening, while scrutinizing chemical analyses from the planet, Aelto identified a molecular sequence reminiscent of his previous adrenal research. This sequence closely resembled venenit shadaaga, a crucial component of adrenals, also referred to as Hutt venom. Aelto named this analogous chemical venenit queshaaga, or "Quesh venom." He discovered it could be transformed into a practical compound via a straightforward chemical procedure. Consequently, due to his findings, the Republic initiated mining activities on Quesh.
The initial reference to Bardian Aelto appeared on the Holonet section of the official website dedicated to Star Wars: The Old Republic, the 2011 BioWare massively multiplayer online role-playing video game. His name was first revealed within the game's Codex entry specifically for Quesh venom.
