The Giant in Dragon's Tooth Glacier

Dragon's Tooth Glacier has been around for as long as the Dwarves remember, and the stories surrounding why it's there have been spun since the beginning.
Most believe the glacier was once home to one of the last Giants, some even claiming to see the outline of the Giant's frozen corpse when the sun hits the ice just right.
Whether or not these rumours are true no one really knows, but it certainly makes a good story.
