Once upon a time... Yet in the great future... after all attempts to colonize Mars had failed... Mars was sold to a fast-food company (now bankrupt) which was said to trade uranium. But their networks with merry degenerate clowns spoiling customer's appetite still entangled dying Earth in strong cobweb of business back then.

Later Mars (it had been through dull) had been abandoned until fortune haunters found life in the depth of the red planet. It would have been better if they hadn't done this... Some time passed. There left almost nothing reminds of Earth and Mars and civilizations as well.
