Kronos

Kronos is a "legendary" mage talked about by Wexton the Apprentice. From the words of Wexton, Kronos is a brilliant mage and inventor on the same level as Clannin, Nystal, and other famous mages.

However, Kronos's invention, the Blackrock Detector, backfired badly, dragging characters into an alternate Moonglow populated with deadly monsters, and unleashing the Shadowlords into the world.

Kronos was killed by Astaroth, the Shadowlord of Hatred, a fitting punishment for his folly.
