The domain of the Dragon God Ghilatmul unfurled from the sky, while the Golden Tree that supported the world became the Dragon God's lair. They shattered the balance of the mortal world, and so the Black Ring appeared. From then on, nothing could find the peace of death. If we do not thwart the Dragon God's plot, then when the Black Ring covers the horizon, the land will descend into chaos and sorrow. At that time, the shadows of dragons will blot out the sky... and all the mortals of this world will become their slaves...
--So spoke Melina, the Ringguard, to the stranger.
