Cornelius Wagglehorn, a Human professor of the male persuasion, taught at Corellia University. In the year 1 ABY, he found himself in Tyrena on Corellia. From this location, he employed a spacer (through his assistant) to investigate the situation at the Corellia University research outpost on Talus, as communication had been lost. The spacer's investigation revealed that the Cult of Exar Kun had arrived, forcefully conscripting both researchers and students at the outpost. Consequently, Wagglehorn tasked the spacer with infiltrating and dismantling the cult.
Professor Cornelius Wagglehorn featured as a non-player character within the video game Star Wars Galaxies, a massively multiplayer online roleplaying game which launched in 2003, developed by Sony Online Entertainment, and brought to the public by LucasArts. The game was shut down on December 15, 2011. Wagglehorn's inclusion occurred with the "Exar Kun" Heroic Encounter, which was part of the "Chapter 9" update released on April 3, 2008.
