Zoort

Zoort was an individual from Glakka. When a Rebel Alliance operative, posing as a Glakka merchant, approached an ISB captain Jeffren Brek, he was asked if he knew Zoort or Raurlu Eloz. When Brek received a negative response, he was easily able to deduce that he was in fact dealing with a Rebel spy.

Behind the scenes
Judging by Brek's behavior, it is likely that Zoort was a factual individual, although he could still be a part of Brek's ruse.
