Feudalism , capitalism , communism , liberalism : where do you want to live? This is the decision a new spiritual atom has to make because it has won an infrequent pre-natal lottery in which it didn't even participate. A constraint is that the world (that is the economic system) and not the position in society can be chosen. But it would be unfair to make a choice not based on actual data. For collecting them, an automaton handling the events of the universe back end accompanies the soul to visit the four worlds. After listening to the versions of the animals living there, the monad can finally make its informed yet arduous choice. In the first part of the adventure, Eon (the lucky winner of the lottery) and Aleph (the automaton whose avatar is a stylized, cat-faced tablet) get to know each other and have one of their countless discussions about anything. Having finished the introductions, the quarrelsome couple finally begins travelling. In feudalism , all the world is mostly populated by donkeys servants who are so busy at work all day that they don't even have time to speak with Eon, who however doesn't give up and enter the castle where the reputed to be more talkative and idler sovereign (a fat pig) lives.

After a harsh debate with him about his alleged divine origins, his right to govern the donkeys as an absolute ruler, the symmetry of his hooves and how that unbalanced situation was reached, Eon and Aleph leave the world to explore the second on the list. In capitalism , the pigs-donkeys dualism is apparently superseded by a great variety of animals and occupations , like the prairie dog employee, the vulture mortician, the raccoon launderer, the python developer, the turtle courier, the platypus factotum, the seal acrobat and many more. Apparently, because most of the animals that Eon meets complain about their condition as salaried workers (low wages which let them barely survive, few or nonexistent rights, recurrent economic crisis worsening the inequalities further) and would desire a radical change, even though it isn't exactly known even to them which path to follow (either a violent revolution overthrowing the business owners' dictatorship or gradual and democratic changes). But not everyone is unhappy about his condition: the fishing cat and the lesser panda aspiring entrepreneurs, the okapi physician of the stars, the peafowl adult industry performer, even more the black swan investor, the fox lawyer, the bat tax advisor and especially the pig (owner of the biggest conglomerate in the world) are at the top of the social hierarchy and have no intention to allow reforms to take place. Everything is as good as it is (for them): the only allowed reforms are those which make them even richer.
