Alberis

Alberis was a human male that had lived in the surface world (Overworld) before being sentenced to the Deep Dark. He founded the United Imperium soon upon his arrival and created the Light.

Alberis was later driven mad by the Gatekeeper, Durycus, and turned against his own people after leading them all to their deaths deep within the Challenges. He created the Dweller race after being forced into exile, and occupied the Blackreach caverns. He then launched an attack on the United Imperium city of Redwall and torched it to the ground. This marked the beginning of the Dweller War.

After the Fall of Ancients Crest, Alberis retreated into the Blackreach caverns and was later chased down by West and his armies. Alberis was killed near the final Challenge by West immediately after ascending to an Unblessed Divine, and the Dweller War was ended.
