Kalanis Major was a class M world with three moons. Kalanis Major was the homeworld of the Kalani civilization.

In 2377, there was a three sided war raging on the planet between the government faction, the Kalanis Defense Arm and the Kalani Republican People's Democratic Front. This led weapon dealers Gaila and Brunt to go to this planet and sell weapons to all three sides of the war. (ST - Seven Deadly Sins novella: Reservoir Ferengi)
