Erdean region, damned Transylvanian lands. A cracked ore line, a destroyed border of worlds. And - Raid. Countless hordes of dark blood-sucking creatures emerge every night from the waters of the Dead Lake.

From the walls of the fortress, the fierce assaults of the evil spirits are repelled by the order knights of Master Bernhard, the Russian warriors of the governor Vsevolod, who came to their aid, and the Tatar riflemen Yuzbashi Sagaadai. However, not all is well within the Watchman itself. There are rumors among the garrison about a mysterious castle ghoul, the Nachtzerer. And this, it seems, is not the worst thing...
