Aerduin was the capital of the Arch-Duchy of Melcat until the coming of the Living God, Razmir. When Duke Melcat refused to pledge his fealty to Razmir, the wizard destroyed the town and all of his inhabitants. Now known as Aerduin's Folly, the ruins have lain abandoned for 50 years.
Aerduin's Folly sits on the southern edge of the Vergan Forest in the southern half of nation of Razmiran. It was part of a River Kingdom until it was destroyed by Razmir on 17 Erastus 4661 AR. Undead eventually began to rise in the ruins, and the place is now controlled by a powerful skeleton lord, who some claim is Duke Melcat himself, risen from the dead to enact his revenge.
