Star Wars: KotOR - Precursor to War
This representative of Black Sun met Dey Hauk, Kari and Serath when they were looking for the Statue of Taycal. He later found out from Krogar Kalvin himself that a data disk with information about Taigon's planetary defenses had been hidden in its base. After finding this out he put a price on the party's head.
Thaigo offerred the group a way to work off their bounty by intercepting spices Krogar was selling on the Erin Moon Resort on Yaglu's moon. After they accomplished this he also offerred them a Sith holocron in exchange for the disruption of Krogar Enterprise's droid factory on Yaglu. The group succeeded but where only given a Jedi holocron.
The group then saw a telecast in which Krogar Kalvin announced his ascension to Primer Minister of Yaglu and Thaigo as his Vice Minister.
