The four horseman were always viewed as powerful beings that are bringers of the apocalypse. Things that destroyed humanity for the devil and god. Four experimental humans were given great strength and power through science that humanity gave them the names of the four. They all were normal human's until they were taken and experimented on. Now whenever someone gets close to them they die in a way that depends on which horseman they were closest to. So what will happen when they are taken to a fantasy world and become the actual embodiment of their names.
P.s. This story will be from death's POV the entire time
