The Guild has learnt in the past few years of a method of personal enhancement known as Evolution. Little is known about it at this time, as those who have knowledge seem to wish to maintain a high level of secrecy about what this entails and how it enhances.
It is believed that races Evolve differently, the true nature of their being coming to the forefront when this occurs. It is known that Hunters can identify if this potential has been unlocked in someone merely by looking at them.
The Guild has so far encountered Evolved Vampires, and it is specifically noted that the antagonistic group known as Ordo Dracul has many of their number enhanced in this way.
Evolved Humans have been encountered more recently, and this has led to theorising about Evolution of other Races, though no information on this has been found at present.
