Urgoros

Urgoros is a specter from Vhelnish on Dominaria, who serves Belzenlok.

History
When the demonlord Belzenlok bestowed the dark "blessings" of dementia magic upon his followers, many died or were transformed into monstrosities. Urgoros's fate, however, was unique: his body was siphoned away into dementia space, but his spirit was fused into his armor. Mounted on a nightmare-steed, his specter terrorized the skies of Urborg, punishing all who dared defy the demonlord.

Urgoros was the second defense against the attack of the Skyship Weatherlight against the Stronghold. He lived inside an Urborg volcano. He vanished when Belzenlok died.
