This city of bones rises like a skeletal mountain from the sands. Its walls, streets, and structures are built from the bones of ancient beasts with fresh human skeletal additions. In the deepest catacombs, necromancers weave death magic, harvesting the bones for dark rituals. The dead here do not rest—they walk the streets, reanimated as sentinels or unwilling servants. Those who venture too far may find themselves bound to the city, forever part of its macabre construction. The city has a sentience of its own, as the souls of the creatures whose bones were used in its construction see through the eye sockets of skulls and move the bones from which the gates and walls are built.

Side Quest - The Bone Colossus

Deep within the city lies an ancient ritual chamber where necromancers are building a Bone Colossus, a monstrous creature made from the bones of massive monstrosities and behemoths of the desert. The adventurers must stop the ritual before the Colossus is unleashed upon the world.
