The Earth groaned and rumbled again then began to crack around the site of the spiraling energy. A ear splitting roaring could be heard for miles. The cracked ground began to fall into a large cavern. Molten rock flowed like a river hundreds of feet below. The Ritual site stood atop a white stone tower that extended from the flowing rock to the surface. Only the ground supported by white stone arches which converged on the tower and spread out into the walls of the cavern remained stable and safe to walk on. But it was open ground and one would easily be spotted if they attempted to cross. Another roar and a groan, the river of lava was as turbulent as the ground, splashing up around the tower's base and cooling, turning to obsidian which kept the tower standing.
