FILÉ is an ocean planet, completely covered by water.  The gill-breathing Filéans constantly follow its currents in peace.  They are ostensibly ruled by a hereditary king, whose laws are absolutely obeyed by everyone on the entire planet.  The only laws which are seen as fit for the king to proclaim, however, are the laws of mathematics.  So no one may claim that 2 + 2 = 5, for example, but other than that everyone is free to do as they wish.  Mathemeticians on Filé keep busy in proving new laws for the king to enforce, but their society is otherwise decadent.  They have never heard of Kurt Friedrich Gödel.
