Dark Sun: Gulg
Primal magic draws its power from the Spirits of the Land. These nature spirits vary in intelligence, might, power and wakefulness. Quite a few of the more powerful spirits simply slumber, even when their lands are being destroyed.
Many people in the city-states don’t believe in primal magic; if they do, they simply consider a part of either psionics or arcane magic. Either way, primal magic is illegal to use in most city-states save Gulg.
Like Arcane magic, there are two ways to draw on primal spirits energies to power their evocations. They either petition magic from the spirits, or force it from them.
Primal magic is respected in elf tribes, slave tribes, thri-kreen clutches, and villages (even some City-state client villages).
