Night Thrall

Not all creatures of the night are to be feared. Some at least, can be learned from. For those who spend a lot of their life around vampires—perhaps as a servant, friend, or rival, these individuals develop the ability to better interact with vampires. This in turn, leads many to adopt unique abilities like excellent climbing and an aversion to too much sunlight. This also leads many into thinking these individuals are vampires themselves.
