The result of the Dreaming Grotto intermingling, temporarily, with reality. The residents of the villages on the outskirts of Etiel often experience these strange phenomena.

… and I turned, crouched in the snow, craning around the tree. What I saw was a vista. A vista, looking out over a chasm, filled with beautiful colours and shapes, overlapping and churning like waves. The deer stood upon it, but there was nothing to stand upon. It let out no cry, nor did it try to run, and unravelled into the same colours, and the chasm moved up to meet me. I dropped my bow, and I retreated. When I looked back, it was gone.
