Canderous Ordo makes his living as a mercenary, selling his services to the highest bidder. Most often this turns out to be an underworld figure wanting to capitalize on his considerable skills as a combatant, tactician, and outright thug. If his criminal clients knew where he learned his trade, however, even they might have second thoughts about hiring him.
Canderous is a Mandalorian, and as such, he was on the losing side of the Mandalorian Wars with the Republic. He was no foot soldier, however, and had an active hand in the planning and execution of many battles that did not go in the Republic's favor. There is a lot of blood on his hands, and he doubts that enough time has passed for people to view his actions as he does, with the impersonal eye of a career soldier. Likewise, he takes no insult from the defeat of his people. It was all just business.
For now, Canderous spends his time employed by Davik, a crime lord with influence throughout the Taris undercity. The traitorous actions of Revan and Malak and the current aggression of the Sith have distracted the citizens of the Republic to the point where they are no longer concerned about defeated enemies, and he can go about his business in peace. Working as a smalltime enforcer is not how he pictured his career ending up, however, and any offer for more interesting work would likely get serious consideration.
