Ki

Ki (pronounced: /ki/ kee), also called inner power or inner energy, was a mystical energy of the body that could be used to fuel various powers by its practitioners. It was commonly used in Kara-Tur. Many monastic traditions knew it as ki, but other names were possible.

Ki was an internal energy of one's body, described as either spiritual energy or the energy of life. It was a subtle energy, but it could be used to perform incredible feats by pushing the body to and beyond its physical limits. Mastery of ki gave one power over one's own body and over the bodies of others.

Ki has been variously considered to be similar to but distinct from the mental energy utilized in psionics, to be a form of psionic energy itself or a magical energy that worked with psionics, and finally as a wholly magical energy. Of the magic that suffused the multiverse, ki was the element that flowed through living bodies. Its application created magical effects. It was also theorized that the martial adepts of the Sublime Way drew on the power of ki and their own souls, but this was unproven.
