HALLAXA is home to a "college town" where privileged students from other worlds are sent to receive a prestigious university education.  A great deal of emphasis is placed on competition and being the absolute best at whatever they set out to do.  Ordinarily, everyone is very serious and formal.  But on the great public holiday of "Bejaunting Day", supreme permission is given to do anything at all, "as long as it doesn't harm anyone."  On this day, the students therefore compete to do the craziest stunts they can imagine, subject to the restriction against harming anyone.  In addition to the threat of expulsion for violating that rule concerning others, there is always also a formal reminder that "anyone" includes one's self.  Thankfully, injuries requiring official discipline are rare.
