You play as Azaus, The Untiring, the last of the Holy Exorcists, ancient creatures that protect humankind against the demons. However, for a thousand years there has been peace. The world has forgotten the evils that lurk below and has grown complacent. Azaus has not. Azaus remembers. He knows that Hell never sleeps and the longer the silence, the stronger the storm. His quest has driven him to The Old Cathedral, where he will face unimaginable terrors.
