From the introduction:
The Ancient Greek World, during the Age of Gods and Men: Zeus, father of all the Gods has decided that he wants a new religious festival for the Mortals to honour him. He has declared that it will be known as the "Olympics" and shall be held in the most worthy city–state in all of the Greek World — anywhere from Iberia to the Black Sea.
But there are more city–states than Zeus can be bothered to remember, so to discover which is most worthy, he has chosen a number of his Godly offspring to do it for him. They will be known as the "Mount Olympus Committee", and will report back in four mortal years, or Zeus shall rip all of Creation asunder.
