It is an age of heroes and epic tales. The Roman Empire has receded from Britannia, and those who remain behind struggle to retain civilization in the wake of invasion...

But this time, the invaders are not mortal.

Across the continent of Europa, a plague is spreading. The dead rise and stalk the living. These revenants bite brings death, and worse, to their victims. They've ruined city after city on the mainland. Now their claws sink into Britannia.

But the small island is not without its heroes. A young Arthur must rise to the challenge and defend his people, or the last lights of humanity will fade from the world.
