Bios Crystal

The Bios crystal is an ancient crystal that has the power to give life to any inanimate object within a certain radius.

Convexity
Convexity originally found the Bios crystal in a forest on the Third Island (The Phoenix Island) however it is not known if the crystal had ever been discovered before him. He used it to create a small army of stone and tree warrior to raid the Phoenix's home tribe, he kept the crystal until soon before his death when it was taken by Horatius.

Horatius
Horatius stole the crystal soon before Convexity's death and kept it as his own. Some say that during his time in the Chroniclers library his books would often come to life and speak for themselves, this would be likely due to the Bios crystal. He later buried the crystal under a lone tree in the ancient grove so that Spyro would one day encounter this tree on his journey to find the Chronicler.

Arborick
The Bios crystal was the magic that gave Arborick life, after his death Malefor found it in the ancient grove and took it for himself.
