Quadratic Sphere

Quadratic Sphere (or Quadrium Sphere) is the name given to a material consolidation of Heraldic magic in physical space. When seals of Heraldic Arts are brought together, they naturally form into a sphere of immense potential power. A Quadratic Sphere's release of energy must be "detonated" through exposure to a Quadratic Key or another high energy source. Such energy will set off the chain reaction within the Heraldic seals, much like the detonation of a bomb.

Perhaps the largest, most powerful Quadratic Sphere ever created was the Sorcery Globe - made by the Ten Wise Men roughly four billion years ago. As the Ten Wise Men lacked a Quadratic Key, they used their own energy to initialize the sphere. Later, Rena Lanford unknowingly carries a Quadratic Key to the Ten Wise Men, enabling them to immediately unleash the power of the Sorcery Globe.

Quadratic Spheres are commonly used in all the Star Ocean games. The Federation, including the Calnus, uses Quadratic Spheres to power their ships as they travel at faster-than-light speeds. Federation ships detonate their ship's spheres through the energy released through matter-antimatter reactions.
