The Crystal is barely distinguishable from the ice that it grows within, which would explain it’s obscure existence. In the Valkte’s earlier scrolls, they talk about how the Crysallis embedded itself in their flesh and speaks to them, not with words, but depicting understanding in their minds, communicating through the fine tendrils that stretch out throughout their bodies.
The shards that protrude from the Valkte’s bodies, glow with a soft blue and appear frosted - it creates an aura of frost that coats their fur, mostly around the tips of their tails, horns and shoulders.
The Crysallis has been known to change colour depending on the nature of the Valkte. For example, when in their Bloodlust form, if they consume an excessive amount of flesh, their Crysallis will turn red and their forms changed into a deep red shadowy creature - a Crimson Stalker.
The Valkte are able to manipulate certain elements of snow, ice and wind through the embedded Crysallis in their flesh - it also grants them the ability to harness and forge the crystal into weapons, armour, jewellery and other objects.
