Order of the Vampire

The Order of the Ghostslayer and Lycan, one that focus slaying the undead and the other becoming cursed beast, were in fact inspired by an older, ancient Order that the Blood Hunters used to follow to possess the power of darkness. However, one day a disaster was brought upon the Order by a group of monster hunters that despise the Blood Hunters of old, to which all other members of the order had died out in the chaos. Since then, the Order became a lost legend of centuries, while new Order's began spreading across the Blood Hunter traditions. But then, new generation of Blood Hunter's have finally rediscover the lost tomb of the destroyed order, delving deep within the lost sanctum and at last found ancient scribes that contain the secrets and methods of the lost Order.

The Order of the Vampire require a special ritual of transferring the blood of a high-level vampire through the Blood Hunter body, becoming a creature that isn't alive or dead, a Night-Walker. Possess superhuman strength, speed and agility, these vampiric hunter also used this 'curse' against other creatures. With the power of a vampire, they can now regain the lost of blood's they used for their rite by draining the life of any living creature, while also learning to manipulate their own bloods as weapons against their foes. They also learn to master the other abilities of a vampire, such as shapeshifting, regeneration, climbing on walls and more. Although Vampire's possess certain flaws as undead creatures, the Blood Hunter's were able to altered and fix some of the issues, though only the weakness to sunlight and running water remain. Those that embrace the dark nature of their curse learn to harness their vampiric gifts, but also succumb to the evil, vicious temperament that driven by their unnatural thirst for blood.
