In the God-forsaken world, Vampires ruled the night. They are creatures of supernatural origins forever bent on the hunt for humans. Each bite by a Vampire spread the curse, corrupting the humans into a lesser degree of a Vampire itself. The curse amplified their hunger, forcing this process to go on and on until the resulting Vampire is so degraded it could produce nothing but death to their victims, sucking their very soul dry.

Cunning Vampires, the First Born, devised a system which keep Vampires' existence a secret, allowing them to blend into human's society undetected. This ensured that their primary source of food remained plenty. Times and times had humans glanced at the shadow of their existence, creating the cultural references for Vampires. Some of them are facts, while others are mere fabrications of human's wild guesses.

As time went by, more and more humans learned of these creatures' existence. Aware that general populace would regard them as delusional, these groups went on into underground warfare against the Vampires, acting as the sole guardian of the human race against these creatures of the night. For centuries the war of attrition waged on. Casualties piled on both sides as the only acceptable end of it is thorough extermination of the opposition.

Amidst the dust of war, something else moved unknown, unseen. Wielding superhuman power, they are avatar of vengeance against Vampires. One of such thing was able to decimate a coven of Vampires by themselves. They are, however, not an ally of humans; bent solely on their own goal, their only purpose was to hunt the Vampires without the need to care for humanity at all.

One such creature started to move toward another goal: not for revenge, but toward the end of this tragedy. The eradication of this war, once and for all.
