Primal magic

Primal Magic was a form of magic associated with both the natural world of the Prime Material plane, and the Spirit World. It was considered one of the primordial forces of nature, one that served as a bulwark against extra-planar threats and influence.

Nature of Primal Magic
Nearly all aspects of the natural world were somehow linked to primal magic, including: all variety of animals, flora and vegetation, weather patterns, and even a planet itself. In some locales in the cosmos, plants produced fruit imbued with primal magic that provided amazing benefits when eaten.

Primal magic was considered 'untamed' and even alien by denizens of other planes of existence such as the Feywild, and could be used to bolster the barrier between planes that was naturally weak at fey crossroads.

The power of truenames each originated from primal magic.

Creatures
Despite the inherent conflict discord between the Feywild and the Prime with regards to primal forces, some fey creatures such as dryads possessed powers associated with primal magic.

Organizations
Primal magic was often associated with those that made their home in the wilderness and tended to nature, such as druids shamans, and barbarians.

The practice of primal magic was notable among the shapeshifters of Dambrath circa the late 15 century DR.
