License to drill!
- a long forgotten remnant of an ancient powerful civilization. It was only a chance collision with a burrowing Terrafin that led to his systems firing up again. By Arkeyan custom, Drill Sergeant was then obligated to become Terrafin's servant. This didn't sit well with the dirt shark, so his first order as master was for Drill Sergeant to not serve him at all... a command he continues to follow zealously to this day.
