Mate is a construct created by the pirate captain Morric to assist with the daily operations and plunders of his pirate ship, the Crimson Wolf. Mate, as his name would suggest, served as the elven captain's first mate, charting courses, picking targets, and handling the overall management on the ship. Mate wasn't just created for tasks on the ship, though, as he was also designed to raid and plunder other ships. Morric integrated a set of the thieves' tools into the body of his warforged so that it would be able to crack into protected parts of an enemy vessel or open secure chests full of valuable treasure.
After a series of raids that were unlucky, the fickle crew of the Crimson Wolf turned to mutiny, stabbing Morric in the back in an attempt to take over the ship. Mate and a few loyal crew members put up a fight, but in the chaos the ship caught ablaze. The mutineers escaped the wreckage on a lifeboat, but Mate and the other loyal pirates were left to die, as all but the construct were mortally wounded anyways. Mate survived the sinking by floating on a piece of the hull, until he eventually reached a small island fishing village.
He worked with the fisherman for a time until he was able to secure passage back to the mainland. Not wanting to take up the sails on a ship without his creator and deceased captain, Mate resolved to put his skills to use in other ways, as an adventurer.
