The Sightless

The Sightless is an entity that, during the Age of Arcanum, made a pact with the arcanist Clemain Astural.

History
During the Age of Arcanum, Clemain Astural, a powerful arcanist, had peered into the Far Realm, a realm beyond the planes, in search of power that would allow him to cease war around the world. Within, he found the Sightless, with whom Astural made a pact under the belief that the entity would serve him. As a result, at the cost of his sanity, Astural's power grew, fueled by the Sightless, allowing the arcanist to sweep devastation over southeastern Tal'Dorei until he was killed by a group of heroes at Wrettis.
