The rings and their four intersecting lines had not been simply drawn on the floor - instead they had been etched as deep grooves into the wood, splintering the boards, and filled in with what looked like thick rivers of congealed blood. In the negative arches between the lines and rings were what looked like runes and mathematical equations - arithmancy perhaps? The eight rings at the end of each spoke of this strange wheel were not empty either.
