Deadly Knight

A skeletal knight atop a skeletal horse. This skilled knight once served a certain king, but for whatever reason was killed unjustly. The knight's resentment lived on into its current form, but it has no target to unleash its anger upon with the passing of the king the knight once served. With nowhere to go and no way to vent its anger, it now wanders the land seeking for someone it can avenge itself on, and a place where it can finally rest in death.
