The Black Citadel of the Fire Giants is located in the caldera of the largest volcano in the Mountains of Fire. This enormous city is built from obsidian and black rock, and has several layers of walls.

In the outer layers of the citadel are the barracks, armory and smithies of the Fire Giants. In the inner layers of the city you'll find the noble quarter and the royal chambers.

They extract precious minerals from the caldera, the sea of magma, underneath their city.
