Psionics

Psionics are mental powers based off of the neural connections inside the brain and the networks of invisible currents between sentient beings. It's represented mechanically, within DND, by KibblesTasty's Psion class as well as the Psi dice subclasses for a number of main DND classes.
Psionics is unusual to find in Holders but often found within the psionically connected races like the Skathári and outlier groups such as the Dreamers.
