Corporal Wasser was a Confederate marine who served on Raydin III during the Guild Wars. He was part of a Tactical Response Squad led by Captain Jack Larimer. He was short but very strong, capable of nearly matching the taller Tychus Findlay in arm-wrestling contests. Wasser's relationship to Captain Larimer was described as that of a "dog" to its master. He was also referred to as a "troll" ... but not to his face.
