Chamber of the Void Prince

Publisher's blurb: A Violet magic swirls within the ancient stone gate leading to the blood halls where two chasms sit either side of an old stone bridge, violet torches flickering in the dark. The main chamber holds a small library and the main function of this place, the many ritual circles to assist in the summoning of some foreign evil. Curved stairs lead you up to the attuning chamber. A round room where magical symbols have been carved into the stone.
