The Lavakin are a race of superintelligent humanoids. They are allies with the Humans. Like the Humans, the Lavakin have 2 arms, 2 legs, a torso, and a head. Unlike the Humans, the Lavakin are capable of surviving at very hot temperatures and have blue skin.
They live life as the Humans presumably did in the Paleolithic Age of the Earth. This includes adopting a Paleolithic diet, exercising frequently with varying durations and intensities, performing a variety of complex natural movements that use the whole body, maximizing contact with nature, trying to sleep at least 8 hours a day, and spending sufficient time relaxing, playing, and just "being in the present", without worrying about later.
Their future includes a decline to extinction in AD 3,200,000, a war with the Protonic Birds in AD 10,000,000, and Gliese 876 exploding in a nova in AD 2,500,000,000.
