The Retreat is an island in the middle of the Pacific Ocean that was created for those who enjoy spending time in a judgement free environment where only the rules of The Retreat itself reign. It is an adult playground, having any sort of adult entertainment one can think of. It was specifically set up within a private, members only, network called The Marketplace where consensual slave training and selling is not only allowed, but accepted. There is a training facility on the island as well as a Marketplace auction. However, what draws most people are the beaches, boutiques, cafes, bars, clubs, hotels, and casino.
Basically it's a meeting place for the rich and famous that provides entertainment such as the world has never seen before. It is a very private environment, allowing no media or paparazzi and all the clients/staff are carefully screened before ever setting foot on the island itself. What goes on at The Retreat, stays at The Retreat.
