Spheres

A Lower Knight's armor cannot deploy until it has a perfect platinum sphere embedded in one of the seven pieces. They are perfectly spherical, flawless crystals of living platinum.

Obtaining Spheres
The spheres form during special conditions around the mouths of the Elements (pillars of fire that rise up from the core of the planet). A large percentage of Lower Knight training revolves around preparing for expeditions to obtain these spheres. They place spheres obtained from around specific Elements to specific sections of their armor.

Sphere Abilities
Each sphere set grants specific abilities to a Lower Knight's armor. All spheres give a boost to strength and duedamus capacity.

Each sphere also carries great significance to the Lower Knights, simbolizing a principle of Lower Knight character. The act of obtaining each sphere is believed to require that the knight fulfill a trial of character involving this principle.

Sphere Caverns
When a Lower Knight enters an Elemental cavern with the intent of gaining a sphere, they will encounter a Guardian that will try to stop them or kill them.

Each specific sphere set for each level of each armor set has a specific Guardian. The Lower Knights believe that these Guardians are actual demons that have been tormenting the knight for their entire life. They also believe that going into the sphere cavern forces the demon to take physical form and face the knight head on, without the luxury of being nothing but a tormenting spirit on the wind.
