''Main article: [[Cava]]''
Cava are a species of bipedal therapods resembling corvids native to Aurora. Evolving from an arboreal climbing species descended from dromaeosaurs, modern cava first appeared in the fossil record 2 million years ago in the [[Ethaln Plains|Ethaln Plain]] and became the dominant sapient species on Aurora. Cava are tetradactyl, and possesshave digitigrade legs with anisodactyl feet. Cava possess a beak quite similar to corvids as a result of their omnivorous diet.

There exists little sexual dimorphism and the species is generally considered to be visually androgynous. The plumage of cava is typically dark, although natural variations of white, grey and blue in various patterns are present across the population, and they have a set of colourful crest-feathers on the back of the head. These feathers strongly reflect UV light which cavan tetrachromatic eyes are sensitive to.
Evidence suggests that for a brief period of time approximately 500,000-300,000 BCE some cava in modern Staynes had developed primitive agriculture before reverting back to hunter gathering for an unknown reason. This happened again around 100,000 BCE in Axdel, with some metal artefacts also recovered, with the reason for reverting back to a hunter gather lifestyle likely being cooling and glaciation forcing migration and a return to hunter gathering. Cava intermingled and shared a range with elven migrants to Aurora in approximately 200,000 BCE and later humans in 50,000 BCE, withboth theof latterwhich settled becomingprimarily increasinglyin the more dominantamenable oncenter and east of the continent. However, few if any Cava migrated north into Yasteria. Cava are found globally, but the majority are foundreside in West Aurora and South Arcturia, with sizeable minorities in Yasteria, the states of the [[PacificCerenerian Ocean]], and eastern Novaris. Some Cava are indigenous to Sempiterna, living in the sparse, snowy tundra at its most northerly points, making them the only sapient species native to the continent.
