The planet Talok VIII is the only habitable planet orbiting the binary star system of Talok. Most of Talok VIII is an inhospitable, arid desert. The natives of Talok VIII are identical to Terrans, except for their bluish tinted skin. Out of every generation on Talok VIII a champion is born, able to wield powers over shadows.

The Watchtower is the secret base of the Justice League of America. It is constructed of promethium and used highly advanced Martian, Thanagarian, Kryptonian, and Earth technology. The arrival of Orion and Big Barda added the technology of New Genesis and Apokolips to the systems within.
Apokolips is hell incarnate. Dark, polluted, and deadly are just three of many bad adjectives one can use to describe Apokolips. Apokolips is the huge, desolate ball of matter wrapped in machinery coating a great portion of its surface. Also characteristic are the massive Energy Pits which supply the planet's light and power.
New Genesis is ruled by a being known as the Highfather, a spiritual leader who maintains his people's connection to the primal energy field known as The Source. In contrast to the industrial wasteland of Apokolips, New Genesis is a veritable paradise covered in lush forests and grasslands. The only urban location is Supertown, a floating city designed not to affect the planet's surface.
