The Witch and the Grimoire

Fate... A person's life cannot be summed up by those two words alone. It takes countless factors to bring about an outcome, some chance and some inevitable. So what caused them to be shackled as witches, burdened with the lives of thousands, even tens of thousands? What lies beyond the path they walk...? The Witches' Pact: The Witch and the Grimoire

Witches are people rejected by the world and sent to this world on the other side.

Grimoires are their true forms. Because they contain an enormous amount of negative energy, when they are destroyed, that energy returns to the world where they originally existed, throwing the world's balance into disarray and even threatening to destroy it. For this reason, witches are not allowed to die. A defeated witch becomes a grimoire, then returns to human form after some time. Witches possess enough power to threaten the world, and the world on the other side is much like a special detention facility.

Pact-Bearers: For a witch to enter the real world, she must make a pact with a human. With a pact-bearer, a witch gains the identity and physical form needed to enter the real world.
