The Riftwar Cycle is the name given to the series of books authored or co-authored by Raymond E. Feist that revolve around the fantasy worlds of Midkemia and Kelewan.
When Feist studied at the University of California, San Diego, he and his friends created a new role-playing game based on their own original world of Midkemia.
The original group have since formed a company called Midkemia Press, which has continued publishing campaigns set in that universe.
As a result, much of the background of Kelewan – the Tsurani Empire, the lack of metals and horses, the Cho'ja, the pantheons of 10 major and 10 minor gods – comes from Tekumel.
On February 2, 2022, Six Studios, a production company started by Jeff Huang and Carl Choi, announced it would develop the first six books in The Riftwar Cycle into a TV series.
