Loggi is probably the last remaining relative of Harkyn Grymstone.
A warrior in his own right, Loggi decided not to take up arms against dragons, but instead chose the life of a blacksmith and miner.
One day while traveling with a group of miners near the Alterac Mountains he was beset upon by the Scourge. Being stuck in a cave, they were contacted by a certain baron to dig up creatures from ancient times.
However, Loggi got caught shortly after and was presumed dead, until Kalec and his group arrived.
