Long ago, in another world, their was a place known as Yharnam "The City of Blood, Home to the Healing Church." The healing church, founded by Lawrence, "The First Vicar," were known for giving away "blood," a mysterious element, gifted by the "Great Ones." The Great Ones were mysterious beings that came to their world to establish themselves as Gods, to the lower lifeforms. Blood was said to have the ability to heal any wound and cure any disease. They planned to supply it, then great harm in a situation to make them look like heros, to the humans.

However, their was a dark, unforseen side affect. Whoever used the blood, would lust for it so much, they would lose their sanity and mutant into horrorifing, man-eating beast. Solutions to the problem ended in failure and even back fired at times. Then, came the hunters, the first were mercenaries, in it only for wealth. The next of was the remaining townsfolk, who wished to take back their homes. The last, were out of towners, who simply seeked a cure for a disease, or wished to study the blood. Only to be thrust into the nightmare that once was Yharnam.

At the end, only two things remained in Yharnam. The beast that were once the townsfolk and animals of Yharnam, and the hunters, how have lost all reason why, but hunted the beast none the less. As these events took place, the Great Ones did want they could, to fix it. The Moon Pressence made a pact with Gehrman, "The First Hunter." They created the Hunter's Dream, to assure that know matter how many times a hunter dies. He will always come back, remaining undying until all beast where slain.

This only lead to more problems, such as hunters losing sanity and turning to beast themselves. Mergo and his Wet Nurse, locked up the worst of which, in the Hunter's Nightmare. However all they could do is watch. Watch how their meddling lead to the damnation of an entire city, watch as the Hunters learned, watch as they got stronger, watched, as they completed the hunt.

The cost however was to great, when one becomes a hunter, they have more in common with the beast they hunt, right off the bat. When a hunter spends time hunting, that becomes their purpose, to hunt. Knowing the Hunters could never go into regular society again, and desperate to cover up their mistakes.

They sent them away, to another world, far out of reach for them to be retrieved. A world known simply as Remnant, a placed plagued with dark beast known as "The Creatures of Grimm." Unlike the Beast of Yharnam, the Grimm were born of darkness instead of human flesh. They taken most of the planet for themselves, and are numerous. It was perfect, here the Hunters could hunt for millenia. Since the nature of the the local Huntsman and Huntresses, is roughly similar to the Hunters of Yharnam. There was a slight chance they would become heros.

So they left them. They left a band of people who could hardly be considered human, to do the one thing that they do. To hunt.
