History[]
In his early life he was a good friend to Dejah Thoris, she considered him like a brother and the two were schooled together. He became a spy, and one of the best men in the service of Gunbor.
He was sent to track down and eliminate Mortus, a assassin guild leader who had become greatly feared in the Barsoomian underworld who had begun to wage war against Helium from the shadows.
Tok Nur formulated a plan to meet with Xam Lin a leader to an assassins guild that rivaled Mortus', but he was killed and returned with the letter M carved into his chest before he could fulfill his plan.
