R.M. Merik

Captain Merik attended Starfleet Academy with James Kirk, but failed to have the 'right stuff'. He was thrown out in his fifth year, and became a commercial Captain. His ship, the Beagle was captured by Magna Roma. Merik was assimilated into the society, as were many of his crew. The rest were thrown into the arena. Merik became Merikus.
