Ancienite

Ancienite was a magical mineral, originally found only on the planet of Keystal. However, enough of the planet's crystal coating wore off during The Escape From Keystal that you can find the substance in many corners of the triverse.

Properties
All Ancienite crystals contain a strange liquid the coloration of which is dependant on the sub-element the crystal exists. This liquid, known as elemental essence, is completely drinkable, however drinking it may lead to mutations. In times of need, the crystals gain the ability to be absorbed into somebody's body, and cause them to gain the element inside the crystal. During these times, the crystals are more prismatic then normal and seem to glow. The sub-elements inside these crystals are Sun, Moon, Rainbow, Treasure, Olympus, Seasonal, Apocalypse, Dream, Snowflake, Monolith, Ornamental, Aura, Chrysalis, Gemstone and Galaxy. Together, these elements are called the sub-elements, but some people consider them all variants of a fourteeneth element, often called quintessence, dragon, or legend.

History
Before Keystal was covered with rocky sediment, it's entire surface was made of Ancienite. All of this Ancienite was infused with the snowflake sub-element, meaning that the planet was very cold. The Ancients only source of hydration, at the time, were these crystals, as the elemental essence inside was only drinkable liquid.

However, when the Ancients abandoned from Keystal during The Escape from Keystal, some of the Ancienite that made up the planet would be blown into the atmosphere. It's unknown what truly caused the Ancienite to be blown away, however theories state that when asteroids and comets hit Keystal, it would release chunks of crystal that would become asteroids made of Ancienite.

Later the Ancienite became stranded all through out the triverse, though it mostly crash landed in the DragonVale universe and the Universe of Humans, AKA our world. It's unknown why these two universes were such a common crashsite, however pieces of Ancienite would adapt to where they landed, leaded to the other varieties of Ancienite. Eventually some Earthly animals and Valian dragons would eat the Ancienite crystals, leading to the creation of epic dragons and the Society of the Elemental Animals.
