The Investigation Division of C-SEC never had an officer quite like Tumo Shaan. Serving with distinction, Tumo closed a large number of cases, including several cold cases that had been abandoned for years. The Drell's eidetic memory, perfect for investigation work, allowed Tumo to pick out tiny details and build up cases around them. Unfortunately, this did result in a few cases being thrown out of court with evidence described as "tenuous at best".

After 15 years of service, Tumo announced his retirement. Tired of the political red-tape that allowed obvious criminals off the hook, Tumo opened a Private Investigation business called Shaan Investigations. Catering mostly the citizens of the Wards, Shaan Investigations did have a few high-profile clients. One such client was a Hanar merchant named Nelour.

After Nelour was brutally murdered Tumo set out to investigate. It's unknown if he was working for Nelour at the time or not but he has dropped all other case work and seems obsessed with finding Nelour's killer. He has followed a trail of clues for months that have led him far from home, and into the Terminus Systems.

Finding the region full of pirates and slavers, Tumo has signed up with the Terminus Lancers in an effort to gain the safety of a larger group while he searches for Nelour's killer. Perhaps in this lawless frontier, Tumo will be free to dispense justice to those who deserve it.
