Mysterious magic that was created, controlled, and gifted by the old gods. Before the great war a century ago, most people had followed or worshipped one or more of the many many gods that existed across the lands. These gods would then create divine magic which they would bestow among their followers which they could use as they saw fit.
The limits and capabilities of divine magic is unknown. It would appear that the magic was near limitless as gods had a wide variety of powers and abilities all at different levels of strength. The creation or origin of divine power is unknown and its secrets have been lost to the grave along with the slain gods during the great war a century ago.
