Archium is a rare type of carbon that only exists in celestial areas like Kabrius and Terrahypt. Archium is carbon that has been under extreme exposure by intense fluctuations in the Archaic Field which has changed it's property at the quantum level, making it very reactive near spirits which can move it around by using spiritual force and energy. Archium has become the element of gods because it is too powerful to be in the hands of immature mortals like humans. Therefore, Cythas has made a rule that only his children may be able to harness it's powers.
When Archium is being controlled, it only takes a little portion of it to cause great damage since it can be moved around faster than the speed of light, which in turn can destroy city blocks without being cautious.
