Celestials are beings of immense power plummeted from the sky in The Elder Scrolls Online.[1]
They appear in the region of Craglorn where the Celestial Warrior leads an army of ancient Yokudans in the west, while the Celestial Mage commands a torrent of atronachs defiling the land in the east. The Serpent and the Thief are two other known Celestials involved in Craglorn's main questline.[1]
