Rise of the Kingdoms: Gathering of Heroes
The Magic of Threa
The capability to cast arcane magic generally first manifests itself at an early age. It usually then takes several years for someone to figure out how to use these powers, but by the time they have, they have developed their own unique style of casting. This can be used identify arcane mages.
Due to Ilensia being the god of magic as well as elves, elves tend to exhibit the capability to cast arcane magic of any of the races.
Divine spellcasters are more common than arcane mages. Anyone can learn how to cast divine magic as long as they follow at least one god.
The followers of each god each have a different way of casting, though there are some similarities. Most clerics require some sort of symbol in order to cast spells, usually the symbol of their god, though there are circumstances that this isn’t needed, though these tend to be only the most dire of circumstances.
