Landvættir When a group of tourists visit the deserted city of Pripyat beside the Chernobyl reactor in Northern Ukraine, they are hunted down relentlessly by a landvættir, a creature of the old world, mutated by the radioactive poison in the air.
For those that survive the initial attack the lesson is clear...there are worse things than dying
