Teychenne was the Spymaster of Governor Purton of Concord Dawn. After losing his son Lenovar to a killer by the name of "Jaster Mereel," the governor decided to exact revenge on his son's murderer. Teychenne was able to unearth Mereel's background, discovering that he was the famous bounty hunter Boba Fett. She was also able to locate his loved ones, Sintas and Ailyn Vel, and Connor Freeman. After Purton's failed attempt on Fett and his family's lives, and subsequent death, Fett declared that Teychenne was to work for him.
