This spell brings into being a wall of blackness which cannot be seen through, even with infravision or ultravision. It is dispelled instantly by a light or continual light (q.v.) spell. It has no physical existence, and does not hinder nor harm those passing through it. It does, however, block the passage of sound from one side to the other, assuming that the spell is not cast in such a way (such as in a field of grass) which would otherwise allow sound to move around the edges of the wall. The material component is some pitch and soot, or a lump of coal.
