Caitlin drew out a coded map of the various Hells in the cosmos and prepared herself. She bathed herself in various different magical oils in salts and drew out a large, systematical sigil on the floor with black and white sand like a mandala for protection. She turned the various dials and segments of the puzzle box, the various candles in the room lighting themselves one at a time at they clicked and snapped into place as it was instructed in her researched.

She ceased toying with the box as the various gears in the hellish toy began to crank and move on their own. The many candles in the room flickered and began to glow an unnatural light before they all blew themselves out, plunging the young mage into darkness.
