Ostmere
Three hundred years of light
For three centuries a flame burned in the high keep of Ostmere, and while it burned, the dead stayed buried. Then the old king, dying and afraid, fed the flame his oath and begged it to let him live forever.
The Light went out. He did not die. He became the Pale King, and the dead rose with him.
One ember survived. It's in your hands. Carry it down the long road, find out what drank the Light, and light it again.
