Calvin

Master Sergeant Calvin led the Confederacy Marine Corps' 2nd Battalion's transportation company on Raydin III during the Guild Wars.

In 2488 the Confederate military defeated the Kel-Morian Combine at Prosser's Well, and collected a sum of treasure, which was stored in a warehouse under the command of Gunnery Sergeant Sims.

Calvin hatched a deal with Staff Sergeant Tychus Findlay. If Findlay could arrange with Sims to steal some of the treasure before it could be accounted for by a logistics team, they would split the loot three ways (along with some for Calvin's soldiers and drivers). Findlay made the deal, but it fell through due to him being arrested for an unrelated crime.
