Psionics is a supernatural power that manifests in in a variety of ways.
Manifestation of these powers are not explainable by science.
Individuals capable of using psionic powers are rare.
A psionically capable individual does not tap into the mana field of the universe as a magic user does. Nor do they utilize any other naturally occurring force or energy to fuel their psionic powers. Psionics are wholly powered from the mind energy of an individual.
