Mount Celestis

Mountain in the far north of Erdde. It is said to be the dwelling place of The Celestial Pantheon. Other legends describe it as so tall that it reaches the heavens. Since the War of the Elves and the Giants, the peoples of the Empire have been cut off from the mountain by the Giant lands in between.
At the foot of Mount Celestis was (or possibly is) the First Library , its lore now lost to the people of The Empire.
