Elemental magic

Its a magic that stems from the elements. It is said that before Khalas came to Shek there was pure elements that roamed the planet causing chaos and destruction

Khalasadra'Dinarosque, or Khalas, the god dragon came to Shek after he closed the realm of his own. Khalas took in the elementals into himself and re-birthed them as the chromatic dragons and created the realm of elements.

Creatures draw on the remaining elemental magic on the planet which seems to be everlasting.
