Arch Dornan wears the exact same armor as other soldiers, the Mark II powered combat armor. However, underneath the thick layers of metal and servomotors lurks something different. Arch Dornan is the single most powerful personality on the base, capable of reducing even the proudest soldier to a gibbering wreck through the use of ear-blistering rants punctuated with profanities.
Interactions with the player character
This character has no special interactions.
Dornan can be safely circumvented, as unless the player speaks to him, he will remain in the quarters. If for some reason the player talks to him and doesn't reload, he will either post the player at the hangar and start circling the base or, if without power armor, tell them to get suited up or escort them off the base.
↑The Courier: "Who's Sergeant Dornan?" Cannibal Johnson: "He was a drill instructor I knew. He was also the meanest bastard I've ever known. Once, he caught this private out of uniform and old Dornan went off on the most ear-blistering rant known to man. It was inspiring." (Cannibal Johnson's dialogue)
