Tomb World

A Tomb World is the term coined by United Earth Coalition scientists to describe any inhabitable, planetary body that has been so utterly ravaged by pandemic, war, or some other cataclysm that it has destroyed any form of sentient life.

Surface
The surface of a Tomb World can be either a blasted wasteland riddled with craters and the ruins of the civilisation that stalked the surface so many years ago, overgrown cities pockmarked across an eerily quiet surface, or a planetary body all but shattered by the effects of powerful weaponry.

Possibility of Life
While utterly devoid of any of the civilisation that roamed the surface of the world prior to the events that took place there, some forms of animal, bacterial, and plant life may still roam the world to rule the ruins of an ancient race.

Trivia

 * The descriptions of Tomb Worlds in Hierarchy of Seven are closer to the depictions in Stellaris.
