Keywords

• Geas

  Those who harness the power of their own memories to fight the enemies of humankind — the Barbaroi.

  They don the names of history's legendary weapons — Arondight, Excalibur, etc. — inscribed upon them by their Resonants, and draw upon their spirit to gain extraordinary powers.

  Those with the potential to become Geas can do so after completing the rite of gestalt shift.

• Resonants

  Individuals who have gestalt shifted and formed a life covenant with a Geas via emotional bond.

  They safeguard the memories of Geas, which are lost as they use their powers, by staying by their side and assisting them in their fight.

  A Resonant is often referred to as a Geas' "Master."

• Barbaroi

  Demonic creatures of mysterious origin.

  These monsters threaten to wipe humanity from existence — they mercilessly hunt humans to feed upon their memories.

  They cannot be harmed by conventional weapons, and only the unique strength of Resonants and Geas is capable of defeating them.

• Gestalt Shift

  A power by which two destined partners are bound as Resonant and Geas, if they fulfill their potential and their bond is strong. It is a ritual necessary for fighting the Barbaroi. Often referred to simply as "GS."

  Gestalt shift has a "One Life, One Twain" rule — a person can only bound to one partner during their lifetime.

• Factorization

  The act of transforming one's body into a Geas — a powerful and specialized combat form. Only those who have learned to gestalt shift can perform this feat.

  Geas need to expend a tremendous amount of power to maintain their battle form. For this reason, they usually remain in their human form and factorize into battle form only when the need arises.
