The only planet within the habitable zone of the Rawrca system, Zarr offers a diverse range of ecosystems ranging from lush rainforests to arid deserts, and thus supports millions of different life-forms. Of those, at least three species are known to be sentient - the lirrax, the taaria, and the ahm. There has historically been very little contact between these species, as the taaria seldom leave the deserts, and the massive, beetle-like ahm make their homes in caverns beneath the ocean.
