Zagraz Mountain is a forbidding mountain peak on the planet of Eternia. The mountain is named after its sole inhabitant, Zagraz, the so-called keeper of the comets. The old man makes his home atop Zagraz Mountain, where he can more easily study the celestial phenomena in question. He-Man and his companions travelled to the mountain to seek the keeper's aid, and it was the site of a battle when Skeletor, empowered by the cosmic comet, attacked the heroes.
