Chiron

It comes in all shapes and sizes, but most fragments can easily fit in the palm of your hand.

Chiron, also known as Starstone, is an extremely valuable and rare crystal that is believed to be the fragments of a star that was destroyed and split into many hundreds of meteors that rained down on Esshar before recorded history. The highly reactive material that collided with Eternia gradually crystalized, while giving off waves of intense magical energy that naturally attracted wildlife in the area, often mutating them through the centuries.
