I'm new, but I'm interested. What came to mind was a soldier that has taken more than his fair share of injuries, and is bitter about this and at having to run with such brigands, yet has no choice as it is his only available source of income. Perhaps slightly space famous for having survived against impressive odds with two mangled legs and an arm, the remaining arm being used to fire his pistol into those that continued to come down the corridor at him. Grumbles at almost everything.
Thoughts?
