Dain was orphaned by the decimation of his dwarven tribe at the hand of orcs in the Griff mountains when he was just a boy. The few survivors of the attack fled to the coast and were taken in by the Fruztii - frost barbarians of the north, but he never completely fit in.
His growing years were tough, being the shortest of the mostly human barbarian tribes, but the challenge toughened him, and he grew into his manhood with strength if not stature.
Recently, he did what many a barbarian does from time to time, "run amok". He journeyed south and was working as a woodcutter in Pine Haven, taking his rage out on trees to fell, when he met a pair of wizards visiting a nearby parent. They became curiously odd friends due to his fascination with the unique heritage the pair both shared yet ignored. As different as different could be, they traveled together, true companions.
They have been adventuring ever since.
