Even back in its glory days, the city had its problems with vampires. Being undead, these creatures just froze along with the rest of the city, but now they too have thawed out. While a few vampires were powerful wizards or warriors in their own right, most were just another dangerous parasitic creature.
Frost wraiths are a peculiar form of undead only found in the ruins of Frostgrave. Although they are ethereal undead, they have somehow have become partially frozen. Because of this semi-material form, they cannot move through terrain like other ethereal undead, and are vulnerable to normal weaponry. Their icy grasp is, however, extremely painful for living creatures.
