Exploration of the 22 paths connecting the Qliphothic spheres, each corresponding to an inverted Tarot trump. The tunnels are more dangerous than the spheres themselves, as they represent transitional states of consciousness where the adept is between stable states, vulnerable to disorientation.

The tunnels are the nervous system of the nightside Tree, channels through which anti-cosmic energy flows. Each tunnel is a wormhole between states of anti-being, guarded by entities who test the adept's resolve.
