Appearances[edit | edit source]
The Crystals are first mentioned to originate from meteors, though not much detail is given to them.

They appear to be native to Casperion, a moon just within the Dragon Homeworld's gravitational field.
The Legend of Cynder: The Precursor Legacy[edit | edit source]
During the Dragon Civil War, the novels state that Cynder has to eat the crystals in order to be able to use elemental attacks, though how the crystals physically affect her, or if they do at all, is not discussed.
