It’s a common feature of shamanic myths that when a shaman travels to the realm of spirits, he makes use of some sort of vehicle while there. It might be a dugout canoe, a chariot, or a spectral horse, or something more fanciful, but it serves to speed the shaman along his way. This rite allows an Ithaeur to craft such a conveyance for himself, using the Essence that infuses his spirit half.
Performing the Rite
The ritemaster first creates or acquires a small model of the vehicle she wishes to bring into being in the Shadow. This model can be anything from a hand-whittled carving of a dog sled to a die-cast toy car. The ritemaster prepares an ink made from nightshade, woundwort, and ayahuasca or a similar natural hallucinogen, with which he marks the model with glyphs representing the shadow. The model is, finally, destroyed, creating an echo in the Shadow bound to the Ithaeur.
A Shadow conveyance is not a spirit; it is merely a construct of ephemera. Even if the conveyance resembles a living being (and in the Shadow, that can be a broad category indeed), it is a mindless automaton; any resemblance to a real creature or its behaviors are purely cosmetic. The conveyance can only be piloted by the Ithaeur; for any other character the vessel simply refuses to move.
The Shadow conveyance has the following Traits: Durability 1, Size 5 (one passenger), Structure 5, Acceleration 10, Safe Speed 44 (30 mph), Maximum Speed 88 (60 mph), Handling 0. Vehicles are covered on pp. 141–147 of the World of Darkness Sourcebook.
