”The second become Fleshstones, which are what really make us into Crystin.
The Fleshstone is a crystal embedded in the back of the neck of a knight of Crystallia.
Fleshstones are created from one of the three types of crystals that grow in Crystallia. They appear as blue crystals in the back of a Crystin's neck. When removed from a Crystin, they are about the size of two fingers. The act of removing a Fleshstone from a Crystin is considered a deep violation and can lead to the Crystin's death if it is not replaced.
The Fleshstone improves the physical abilities of a Crystin beyond normal human abilities. In particular, it gives them an enhanced speed and strength. It accomplishes this by connecting all the Crystin together through the Mindstone. When one Crystin knows how to do something, every Crystin gets slightly better at it. Crystin can also feel the presence of other Crystin through the Fleshstone. Sensing a Fleshstone is not dependent on the Fleshstone being inside a Crystin. This also creates a weakness in the Knights, that is if the Mindstone is interrupted, an enemy can harm all the Knights through the connection.
