the only thing even resembling nature on parse are the rivers that flow through it - but these rivers don't flow with water. instead, they flow with what the citizens call 'nectar', the liquid that powers everything within the dimension. these rivers that once ran freely have now been taken over by BIOS, domes built over them to keep the power source from being stolen. these domes don't do much to deter those that reside in the junkyard, though; frequently, they're broken into, and nectar is stolen. otherwise, those in the junkyard use what bits of nectar they can extract from the old, broken machines that are dumped outside of the city. those within the city know what nectar is, of course, but they aren't quite as aware of its importance as those that live outside are.
