Sphere of annihilation

A sphere of annihilation was a globe of absolute blackness, a ball of nothingness 2 feet in diameter.

Description
The object was actually a hole in the continuity of the multiverse. Any matter that came in contact with a sphere was instantly sucked into the void, gone, and utterly destroyed, with the exception of artifacts. Only the direct intervention of a deity could restore an annihilated character.

A sphere of annihilation is static, resting in some spot as if it were a normal hole. It can be caused to move, however, by mental effort (think of this as a mundane form of telekinesis, too weak to move actual objects but a force to which the sphere, being weightless, is sensitive).

If a rod of cancellation touches a sphere of annihilation, they negate each other in a tremendous explosion. Dispel magic and mage's disjunction have no effect on a sphere.
