Feystone

When a being - be it plant or animal - that can wield mana dies, it's mana gathers in a single spot, crystalizes and turns into a gem-like object.

Depending on which mana-source was turned into a feystone, their specific characteristics can differ. Different stones can be used to drain, transfer and store mana, can be turned into magical objects via a spell like a Highbeast or Ordonanz or be used to create magic tools.

By dyeing the feystone with one's own mana, it can be morphed into the shape of an animal, that will move according to the user's will and fly through the air. The changes are according to the user's imagination. Nobles generally change it into a mount reminding of animals like pegasus', griffins or some other animal with wings. The Archduke's family in Ehrenfest generally create their beast modeling after a lion with wings. Aub Ehrenfest uses a lion with 3 heads.

Feystones can be used to store mana and can be used when needed in the future. If you exceed the feystone's capacity, it turns into gold dust. The feystones come in different qualities, which means they can store different amounts of mana; the higher the quality, the more expensive a feystone is.

In the same sense, feystones, usually in the form of a magic tool, are used to drain any overflowing mana from noble children that can not yet contain or compress their mana. This was seen when the overflowing mana from Dirk was drained with a feystone.

Black feystones drain mana of any source they come into contact with. The draining will only stop if the target is completely empty, the contact is severed or the stone is fully saturated, at which point the stone is destroyed. Unlike with other feystones, it is not possible for a mana wielding being to cut off the mana-flow on their own, without severing physical contact with the stone or stopping whichever ranged application of mana they are performing, like the Crushing. Only by incorporating them into a magic tool can black feystone be made to only drain excess mana and thus completely save for use, even by children. Among other things they are used to create the magic tools that drain noble children's excess mana to prevent it from harming their young bodies.

Feystones are used in magic tools to enable their functions.

One of their uses is to put them into the bottom of a pitcher. Once the stone is charged via a Schtappe, the pitcher can endlessly pour out water until the mana in the stone is depleted.

Feystones can be acquired by slaying feybeasts or feyplants, as well as infusing certain fruits or eggs from these beings with your mana. One such example are Riesefalke eggs, which can be turned into feystones rich in Leidenschaft's blue mana. Even commoners can acquire feystones by slaying weak feybeasts like Shumil. There is a store on the west side in Ehrenfest's lower city which buys feystones. There is also a way to turn mana-wielding Humans into feystones.
