Turn to the Humans

Magical beings are the ruling class in this universe. Governments are run by them. Those without powers are considered useless, second class citizens and generally live in poverty. There is a single source of power for the entire realm, however no one knows exactly what it is. One day, the power source is taken over by dark forces. They cast a spell on the source that uses the power of anyone who tries to touch it against them.

The magical beings must now rely on the "non-magic" folk they have ridiculed for generations. They are the only ones who can save the world from this darkness.
