The Obsidian Maw

Built into the vertical walls of the Well of Dragons, the Obsidian Maw is a sprawling vertical citadel. Thousands of dragon skeletons litter the caldera floor below, providing both a source of power and a grim reminder of the site's history. Massive chains suspend metal walkways over the abyss, while the roar of molten lava echoes through the hollowed-out stone chambers. It serves as the primary war-room and ritual site for the Cult of the Dragon.

History

The caldera was once a sacred draconic graveyard before the Cult of the Dragon seized it centuries ago. They transformed the natural wonder into a fortress of industry and dark magic. By hollowing out the interior walls and tapping into the volcanic veins, they created a stronghold capable of housing an army. Recently, the site was reinforced with infernal architecture to facilitate a permanent bridge between the Material Plane and the Nine Hells.
