"I'm speechless. I would never in a million, billion years have suspected the Lt. Col. capable of something like this. It would appear that working for him was much less of an honor than I once thought."
In 1 ABY, Quelsh's Corellian Medal of Honor was stolen and Yamagh helped with the search. When Quelsh asked an independent agent to help in the investigation of the theft, Yamagh pointed the spacer to a group of local thugs known as Braggan's Fist. The agent managed to successfully solve the case of the stolen medal and found proof that Quelsh had framed former CorSec officer Kal Braggan for a crime that Quelsh had committed and that he had later murdered Braggan. Yamagh was left speechless by Quelsh's crimes, as he had always considered it an honor to work for a highly decorated officer like Quelsh.
He could be found in the city of Tyrena on Corellia. Yamagh was part of the quest "CorSec Case Files: Stolen Honor" which was part of the Legacy quest line, the longest quest line in the game.
During each server reset, Edbr Yamagh's appearance was randomized, but he consistently appeared as a Human male.
