Sergeant Damien used to run the Drill Demon random event. He brings players to the middle of a large military training area.
Sergeant Damien abducted players and accused them of slacking in their physical training, forcing them to do a number of exercises before being released. He was a harsh soldier, insulting people who perform the incorrect tasks.
Sergeant Damien has since retired from his duties after the removal of Random events and resides in the circus of Balthazar Beauregard, helping out as a handyman as he and Balthazar were from the same unit during the war.
The remnants of his training area, most prominently the run-on-the-spot sign, can be found in the Mysterious Old Man's basement.
