Garg

Garg is a Troll living on the World of Tarna.

Some time prior to Ultima Underworld II, Garg was captured by the Goblins of this world, and locked away into the prison tower. They captured him because he was already a sworn enemy of the Goblins. They feared what could happen, should he break free.

When the Avatar arrived in the prison tower, the hero did exactly that and Garg went on to kill every single Goblin in the whole tower, clearing it for the Avatar. Garg then made his home into the rooms of the late commander, offering the Avatar training in hand-to-hand combat and later gave the Avatar two letters from the freed Bishop.

Trivia

 * Freeing Garg is the easy way to clear the tower. Of course, the Avatar can also do all the work him/herself.
