Revenant

Monty and Simon survived the Stormblood, but not without grave consequences. Whatever method York used to complete the ritual opened a door to something ancient, dark, and evil.

A Revenant.

Now, that Revenant is hunting them. It needs their life force to be completely free.
There’s only one way to get it.

Eliminate them both.

Together, they must face this new threat before it becomes too powerful to stop and destroys them all.
