Dream-Craft is the Art of manipulating the raw stuff that the Dreaming is made of. This art allows Sidhe to change the physical forms within the Dreaming, which can affect the way that freeholds and other sanctuaries of the Dreaming look. It can also affect voile, the chimerical clothing that changelings wear while in the Dreaming. Though Dream-Craft is sometimes considered the exclusive property of the Sidhe, many commoners have excelled in its practice.
