The Kalani were a reptilian humanoid race native to Kalanis Major. They were roughly the size of a Human or a tall Ferengi, with armored foreheads and scaly skin. Four digits were located on each hand, with each digit having an extended thick black claw as long as a Ferengi's finger.
In 2377, the Kalani were fighting a three way war on their homeworld between the government, the Kalanis Defense Arm, and the Kalani Republican People's Democratic Front when Gaila and Brunt arrived and sold weapons to all three sides. (ST novella: Reservoir Ferengi)
