Anoxic

A long time ago, settlers murdered an innocent child. Many years later, a house is built on the land where pure blood was shed.
Inhabitants of the home experience a sense of dread, almost as if the house is out to get them. Living in the home, they become cursed.
Over the course of several generations, the family of the murdered child doles out cruel revenge. Crimes of the past might fade away, but revenge can continue forever.
