The Kuo Toa Psion, a godly Kuo Toa that sprung forth from the minds of its lesser kin. Unlike its brethren, its reality warping power is entirely self sufficient and is put to quick use on those who do not play along. Despite its terrifying psionic prowess, it's actually an oddly childish creature that is easily placated with the promise of fun games. Though playing with a Kuo Toa Psion might be fun at first, adventurers quickly discover playtime for this god never ends.

One of the Psion’s most sinister skills is the ability to shrink the party to mere inches tall and imprison them in a miniature faux town or dollhouse complete with puppeteered illusions to keep the fun going. Escaping from this nightmare takes cunning, as the naive Psion, while powerful, can easily be felled by a well-orchestrated deception.
