Wayne Barlowe Yma Expedition Leader
"Whether it was out of love for all life or simply a clinical desire to mend something broken, the Yma took our seared world in hand and began to teach us how to repair it."
―Wayne D. Barlowe

The Yma are a sapient extraterrestrial civilization characterized by a strong sense of conservationism and protection towards alien ecologies. They made first contact with Humans in the early 23rd century, finding an Earth devastated by pollution and ecological decay. As decided by the interspecies accord of 2231, the Yma have since taken responsibility to manage Earth's biosphere recovery projects. Little else has been revealed about the Yma other than that their technology includes faster-than-light travel and their language is made out of whistles and harmonics, with rapid clicking sounds as their form of laughter.

Following the discovery of the Darwin Binary System, the Yma have been the main founders and developers of an Yma-Human joint mission to explore the environments of Darwin IV, closely but passively studying the native biosphere and taking extreme care to prevent unnecessary interfering with the native life. The Darwin IV expedition, which took place from 2358 through 2361, resulted in the discovery of dozens of native species including a sapient although Paleolithic race known as the Eosapiens. Since that, the entire Darwinian system has been deemed a preserved area by the Yma and is under constant monitoring from their robotic probes.
