Khorramzadeh

The powerful balor demon Khorramzadeh rules the city of Iz in the Worldwound. He is known as the Storm King, as his form is bathed in lightning rather than the fire usual to balors.

He is one of the two most powerful of the Worldwound's many warlords—the other is the marilith Zuhra Aponavicius. His notoriety has risen in recent years, since his forces managed to destroy one of the wardstones that keep the demons out of Mendev, enabling demonic forces to enter Mendev for the first time in a generation. The attack ultimately failed, but the leaders of Mendev are worried that the Storm King's gain in prestige may enable him to unite a sizeable part of the Worldwound's demonic hordes against them. Their response to this threat was to call the Fourth Mendevian Crusade.
