Glirhuin

Glirhuin was an Adan Poet and Seer of the Second House of the Edain from Brethil. He predicted that the grey Stone of the Hapless would not be defiled by Morgoth, and that it would survive the cataclysmic fall of the Black Enemy and the flooding of northwestern Middle-earth. His prophecy proved true, for the Stone became the center of the island ofTol Morwen.
