Through the casting of this spell, the mage gains the power to physically interact with spirits and spiritual things in the Twilight state, as the Death 2 Touch of the Grave spell. She can also touch spirits and be touched in turn by any nearby spirit. She cannot affect ghosts or affect mental projections (she needs the Death and Mind Arcana, respectively, for those effects).
Free Council Rote: Grasp the Otherworld
Free Council mages cast this rote in order to interact physically with Twilight spirits. While under the effects of this magic, they can make contact with such beings, whether to offer a friendly touch or a closed fist. Adamantine Arrow willworkers use the same magic in the defense of cabal and sanctum.
