Scroll of Qi

Origins
The origin of the scroll is unknown, it seems to predate all forms of written text. It is theorised to be a document by the first Chinese philosopher regarding his revalations about Qi.

At some point it came into the possetion of Marie Guichon, who used it to bond her maid with an assassins dagger to give her enhanced stealth ability and bloodlust. The maid died when the dagger was reduced to rust by Juan Miguel and its sheath snapped by Guichon. The scroll was not recovered and remains MIA.

Effects
The scroll can be used to bind a persons Qi, or life energy, to an object or organism. Doing so gives each bound individual the combined powers of the two. In the case of an individual binding to and object, the user will develop abilities relevant to the object in question. Few reords of its use exist, but the binding of a man and a horse-drawn carriage gave him heightened endurance and speed. One general bonded with his blade and became more ferocious in battle.

The downside to this is the bonded individual's life force is tied to the other thing. If one were to die or be destroyed, both would perish.
