Demon Summon

One of the summoning rituals of the Void, this spell calls forth a demon from beyond the Veil to the caster's current location. In order for this spell to be successful, the correct symbol must already have been inscribed in the room, in the correct material. If the combination is correct, a demon will be called forth, and will demand payment of the scholar in exchange for its services. Should the scholar be able to pay, the demon will then aid him, for a time.

Standard demons provide a variety of services, focusing primarily on combative functions, but some also giving aid off the battlefield.
