The Hero encountered the giant at the ice cave, and soon brought him enough apples to fill his massive hands. In thanks, Brauggi gave the adventurer a glowing gem. His mission completed, Brauggi ventured back to his homeland.
Brauggi is a character in Quest for Glory I: So You Want to be a Hero?
Although it is never said, the ice cave may be the entrance to a network of tunnels leading into the valley from Jotunheim. This is implied because Brauggi says "And now I head home" and steps back into the cave and also because even he could not leave the valley due to the avalanche unless he knew of another way out.
