Kalestones are naturally occurring dimensional gemstones.
Kalestones are dark green gemstones that can be bound with a single drop of blood and have no strength requirements. Once bound to a user, the kalestone can be used to store small items and be withdrawn at will. Half-meter long kalestones are extremely precious treasures.
After accomplishing the initial steps of the Crimsonbright Nine Heavens Diagram, Ji Ning is granted a fingernail-sized piece of kalestone by his mother. He binds it and tests it by storing a shortsword within it. Overjoyed at the gift, Ji Ning requests that his mother help him put it into a belt so he can keep it on him.
