Nihilite

Magic is a force of nature with its source in a crystalline material called Nihilite. Wherever this material exists, magic is possible. The more of this material that exists in a given area, the more powerful the magic. All magical devices use nihilite as a power source and contain a piece of this crystalline material.

The energies of nihilite are completely absorbed by adamite. Where adamite exists, magic is not possible.
