Most oni on the Material Plane pursue their plans for power in the mortal world, but the go-zu oni retain more of their connection to their ancient progenitors in the Outer Planes. They are often encountered near planar gateways, whether intentionally created by diabolists and death cults of all kinds or simply naturally occurring thin spaces in the planar fabric. They travel back and forth between worlds and often consider themselves guardians and guides of the paths of the dead. They may be the first creatures encountered by planar travelers venturing into the realms beyond, and if not precisely benevolent they can be impartial servants who simply assist with the spiritual journey.
