The Basileus Machine, as described by occult scholar Kalina Oretzia, is an eldritch house-like machine "designed by the Devil and powered by the dead". It serves as the main plot element in the 2001 supernatural horror movie Thirteen Ghosts (also known as Thir13en Ghosts). This elaborate and complex contraption physically resembles a mansion with walls made of Ectobar Glass etched with Latin Barrier Spells; at the heart of the house is a central core of huge, mechanical gears and a rotating crest of rings. It requires 13 earth-bound spirits, all of which represent the Black Zodiac in order to work. Once the machine is activated, it will supposedly open the Ocularis Infernum (Latin for "The Eye of Hell") which grants the user unfathomable power and unlimited knowledge.
