Into the Abyss
This ritual allows the caster to step into Hell itself. Why anyone would want to do this is unknown, but some Sabbat claim to have had packmates dragged into the Inferno, or that ancient Cainite artifiacts lie among the Devil's hoards. To enact this ritual, the caster must wash an entire wall with the blood of children; the wall then becomes the portal into Hell.
System: This ritual requires 24 hours to cast, during which the thaumaturge must remain awake. At the end of the ritual, the portal opens, and it will remain so for a number of hours equal to the caster's Willpower. Denizens of Hell may not escape through this portal, though they may attempt to deny exit to any vampires who have invaded their realm of eternal torture.
