Alright. They're the dominant species apart from humans in my world. The only creatures that most people here apparently think of as "normal" are certain fish and bugs. Most of them have powers beyond what normal humans can achieve, and control over certain elements.

The Legendaries go beyond that, having control over certain domains of the natural world. Storms, the growth of plants, even the flow of life and death...normally, when slain, they regenerate eventually. And others members of their pantheon can pick up the slack. The God-Hunters disrupted their regeneration and killed multiple Legendaries, leaving many holes in the workings of the world.
