Cornelius Wagglehorn was a male Human and a professor at Corellia University. In 1 ABY, he was present in Tyrena on Corellia, from where he hired a spacer through his assistant to find out what had happened at the Corellia University research outpost on Talus, with which he had lost contact. The spacer discovered that members of the Cult of Exar Kun had come and forcibly recruited the researchers and the students at the outpost, so Wagglehorn had the spacer infiltrate and destroy the cult.
