The Heroine Legends universe
At any given moment, somewhere in the universe, a galaxy explodes. The energy from that galaxy travels through the universe looking for a life form that is worthy of its power. While traveling, it begins to polarize into positive and negative energy. Once it comes in contact with a life form, it influences that life form with its energy. Those who are negative attract the negative power. Those who are positive attract the positive. But every so often, the energy chooses an unlikely host. After receiving the power, the hosts must choose if they will use their power for good or for evil.
