Ra'tleihfi (11.9 million)
The more populous of the "Two Worlds", ch'Rihan was settled by Vulcans who never accepted the teachings of Surak several thousand years ago. From there and its sister planet, ch'Havran, the Rihannsu developed into a large, powerful, spacefaring empire.
ch'Rihan is a lush, green, class M planet has no native intelligent life, but a myriad of flora and fauna. About 60% of the planet is ocean, and a very large portion of the planet has a temperate climate with large quantities of arable land.
