Everything

Thaumaturges jealously guard their research. Sometimes preserving a secret is as simple as keeping trespassers out of their libraries and workshops. Legend has it that the Followers of Set created the original version of this ritual to safeguard their hidden tombs and the sacred depths of their pyramids where their eldest sleep. Some secret excursions in Cairo gave the Tremere key components to develop their own version.

Seal Egress allows the thaumaturge to mystically seal a room closed to prevent unwanted trespassers from

entering or leaving it until the proper passcode chosen by the caster is spoken aloud near the entrance. Some Tremere trap an enemy in a small room and allow him to go mad from hunger.

System

To cast Seal Egress, the thaumaturge must spread a point of her blood upon the four walls of the room she wishes to seal and then chant the proper incantation. This ritual is a lengthy process requiring an hour to cast. Each success achieved on the activation roll extends the duration of the ritual by a decade. Seal Egress mystically seals every entrance to the room. Materials from the surrounding walls physically close over any openings into or out of the room, creating a perfect air-tight seal. Trespassers with mystical rituals such as Incorporeal Passage (V20, p. 236) or Disciplines such as Spectral Body (V20, p. 202) find that this room is mystically protected against their abilities. However, this ritual does not strengthen or protect the walls of said room, and thus it is possible for someone of sufficient strength to simply break through the walls of the room. Ghosts, spirits, and other creatures naturally immaterial may enter the room at will. (To bar such creatures, warding circles are required. See V20, p. 234)
