Professor Thlu-Ry, a human of the male persuasion, was in the service of the Galactic Empire during the Galactic Civil War. In the hours leading up to the Battle of Yavin, Thlu-Ry assisted in the concluding alignment procedures for the Death Star, and fortunately departed the space station before it was obliterated. The professor, who was an associate of Cylo (an Imperial doctor who became a traitor), was approached by Darth Vader on the Executor after the Battle of Yavin. Vader wanted to know where Cylo's whale fleet was hiding. Thlu-Ry gave in to the demand, and told him it was in the Crushank Nebulae. After Vader, the Sith Lord, found the rogue fleet, he contacted the Executor to express his gratitude to Thlu-Ry before having the professor executed for being too friendly with a traitor.
The character of Thlu-Ry first appeared in Darth Vader (2015) 21, a comic book from 2016 with writing by Kieron Gillen and artwork by Salvador Larroca.
