Gor is a fictional planet, created by author John Norman(Lange), in the original series of 25 books, published and popular in the 1960s and 1970s, known as Gorean novels. The series has found tremendous popularity on the internet, and the books are now being republished and continued by the original author, with a 26th book in the series recently released, and more to follow. A brief comment (And soon a chapter by chapter summary) on each of the 26 books may be found here at The Gorean Library Under Construction at this site

Existing on the opposite side of the sun from Earth, and hence unknown to Earth, Gor is slightly smaller and has three moons. It contains a highly structured society, based upon primarily male Dominance and female slavery with few exceptions. It has extensive rules for slaves, including elaborate serves and positions. Gor has its own language and meanings.

Gor has become popular at SOI, and many rooms, frequently called Taverns, have grown up based upon it. There tend to be distinctions in the rules and themes of the rooms, but each has as its philosophy, the Gorean novels written by Norman. The books are the "Bible", when it comes to what is or is not "Gorean". On Gor female slaves are known as kajirae, and a single female slave as a kajira. One fine kajira has established a web page to list and describe each of the known Gorean rooms at SOI. Reference to it is helpful as you begin your exploration of Gor:

GOR is NOT fair. GOR is NOT just. GOR is NOT for all. But for some, it is heaven. On GOR a slave always has the last two words in any conversation with a Master: "Yes, Master." I invite you to come and visit, and if you like, Join us, make your home in GOR at SOI.
