The ninth source of magic power has appeared in the world. That aura is the smell of death, a familiar feeling.
In the direction of the Thorn Empire, an unknown distance away from the Holy Dragon Kingdom, on a cliff that pierced through the clouds, the Death Dragon King, Nidhogg, looked up with a gloomy expression. At the end of his vision, the sun was swallowed by a layer of shadow. At the bottom of the cliff where he was, the earth shook as skeletons crawled out of the ground.
Those skeletons had strange shapes, including people in armor, creatures from other races, and even the bones of gods that exuded divinity. After they appeared, they looked up at the sky and let out ear-piercing roars. Under the attraction of the black sun, they flew toward the sky. During the flight, those undead skeletons had turned into pure black mist.
