undead, it is the vampire that is probably the most terrifying. Part of it the terror it generates is simple revulsion at the vampire's physical form -- an emaciated, almost rodent-like mockery of the human countenance -- but there is more to it than that, as there are many monsters whose appearance is as hideous, if not moreso, than that of the vampire. Equally terrifying is the vampire's mockery of both mortality and immortality, its cruel reminder that all existence depends upon sucking the life out of other beings.
There are three known ways to become a vampire. The first is to voluntarily seek out this undead state through the use of Chaotic rituals. Comparatively few vampires are created this way any longer. The second is to be drained of one's life by a vampire and then chosen by the creature to be one of his thralls. This is the most common way that vampires are created in the present age. The third is is a variation on the first, in that Chaotic rituals are employed but the vampire is forcibly created against the wishes of the person affected by those rituals. And, just like the first method, this one is quite rare at present, as the rituals needed are possessed only by a few secretive cults.
Like liches, vampires frequently become leaders among the undead, cowing lesser types into their service. After the fall of the Thulian Empire, a number of vampires associated with the cult of Turms Termax took advantage of the ensuing disorder to establish themselves as warlords in several locations, most notably the military base then known as Fort Adamantas. Over time, most of these vampire lords were overthrown, but some survived, either fleeing into hiding or continuing to rule from their strongholds. With the opening of Dwimmermount, there are stories of yet more Termaxian vampires appearing in the world -- which does not bode well for the future.
