The training ground was located in Alsheem, the castle in Altum and the residence of the Demon King and Queen.
Zuriel now lived in the tower of Alsheem, the Citadel of the Underworld. Elisia remembered how Zuriel hated that tower, but he had no choice because that tower was the symbol of the Demon King's power.
It was designed by their father. Built with the mixture of sweat, blood and flesh of the sinners sent to the Underworld.
Alsheem was large enough to shelter millions of powerful demons, Zuriel's vast army.
Twelve wide, round towers formed a protective wall around the castle and were connected by massive walls made of black stone.
Metallic windows were scattered generously across the walls in a plainly random pattern, along with small holes for archers and artillery.
A huge black gate with a big crenelations was guarding the inside of the castle.
Thane looked at the tallest and darkest tower standing proud in the center of Alsheem.
