The Dark Planet

This is an idea from sci-fi that might be a challenge and place of interest:<div><br /></div><div>The Dark Planet, a planet with out sunlight that still hosts life, has an atmosphere and a climate that supports strange life adapted to the dark conditions. Such a world would defy our ideas about life, present challenges to PCs and have lots of mysteries including why the planet is teaming with life. The planet could be considered mythic until found but could play a role good or bad in religion or customs of a core 4 culture. Planet could hide dangerous sentient aliens, ancient relics/cultures, pirates, big game hunters, be someones science experiment, combat training, sacred place/damned place, prison, royal graveyard and more... </div><div><br /></div><div>In considering life I suggest creatures who hunt differently, attract prey, plants that glow, carnivorous plants, blind creatures, heat, smell &amp; sonar sensitive life forms. Psionic creatures? </div><div><br /></div><div>As to how life is supported... well I am open to ideas... strange environment controlling devices or some strange planetary condition. </div><div><br /></div><div>Could be a real challenge running an adventure in pitch dark conditions except for light produced by volcanoes, natural rock formations, plants &amp; animals &amp; your flash lights... </div><div><br /></div><div><br /></div>
