Magic

Magic is a protean energy that exists in the planes at varying levels, through many means, and in differing forms. The origin of magic is disputed, but common belief among scholars is that raw Magic exists mainly between the planes and binds them together into the great cosmology, and often bleeds into certain planes one way or another. In the Prime Material, magic is far less common than in others, typically being present due to rare magical bloodlines begun by the boons and curses of extraplanar entities and the heritages involving magical creatures native and foreign to the plane.

History
It's believed by scholars that the earliest magic users on the Prime Material plane were the ancient Four: Dragons, Elementals, Titans, and Giants. These four wielded Arcane magic and originally ruled portions of the known world, passing on their magic to the other races during the infancy of their existences. The Dragons, who could change their shape, mated with the lesser races to create stronger soldiers for their wars with the other three. The slaves and subjects of the Titans and Giant were fed the dead of the latter, or took remains by force in their rebellions, consuming their hearts and minds to absorb their energies and turning them against their former masters. The Elementals, beings made of magic itself, melded their souls with that of their followers to imbue them with the powers of their element.

When rebellions against the Four came and the lesser races rose to power, they succeeded largely in part to the magic they were given or stole from their former rulers, but also because of the Gods', who bestowed Divine magic upon the young races. And so, wielding the powers of their masters and the gifts of the Gods, the Four were cast aside by the peoples they ruled.

The Arcane
Arcane Magic, sometimes referred to as Mana, is the raw energy of the universe and is often conjured in the form of elements such as fire, water, or lightning. In general, any magic not bestowed by a deity is considered to be Arcane, including that given by some other extraplanar entities. Arcane magic is typically more fluid and changeable than Divine magic, and those who innately possess it through heritage are known as Mages, while those gifted magic by entities are known as Warlocks or Witches. Unlike many other planes, Arcane magic does not pervade the Prime Material as heavily, but raw magic can be found in the a crystalized form known as Mana Crystals. Mana Crystals are used in the creation of magical items, rituals, and by Magicians, people who utilize Mana Crystals through specially created foci to perform minor magical feats.

The Divine
Divine Magic, otherwise known as Holy Magic, is magic gifted to mortals by deities or their servants. Often, Divine magic falls in line with the domain of the deity that bestows it. Gaia's devotees sometimes exist as druids, controlling certain elements or solely manipulating the environment, whole followers of Derizal can wield holy fire - referred to as brightflame.
