Tiko Crystals

Each aspect of the universe is governed by spirits, who have a hiarchealy structure, with the lowest being faires and spirts, the middle being angles, and the highest being the goddess nherself. They all have souls, and when they reincarnate, they have to store their memories as memories cannot be deleted - only changed or turned into something else. so they turn their memories into crystals. Depending on the creature who had the memories before they reincarnete, the memories themselves, and they amount of power they possese, each cystal can have different powers. usually, the crystals are hidden somewhere, and when the soul of the memories touch the crystal the memories will (usually) come back. However, if the soul is manipulated or damaged in any way, (such as turning the soul into raw energy and changing the personality) then the crystal stops being owned by the soul and is up for grabs.
