The Executioner

When the sky grew dark, and shrouds of darkness covered the sky, many things changed for the people of Evoran. Many legends were born telling great horrors that have never been seen or heard before. The dead have never walked on the land of the living before.
The old oak forest that connected the cities and villages for centuries, now holds a new tale of horror. The forest has a new and only inhabitant. When the natives saw the forest dying and its animals fleeing, they moved far away from the forest and took refuge in far villages and cities. By the order of the kings, the forest was investigated by a group of soldiers; however only a few could make it back alive to tell the tale.
In the middle of night when the sky is at its darkest and cold dead silence rules the forest, the headless knight in armor hunts the living. He has remained unseen to the living, but travelers have seen the massacres the executioner leaves behind. The scared travelers watched the butchered bodies of and the trails the heavy warrior had left behind. However no one has dared to venture following the trails to the forest.
The origin of the executioner is yet to be unknown; however the lord of the dead has chosen the right soul to create such a terrifying weapon.
