CW-13.4-923 is a small, earthlike planet in imperial territory, to which the Kiravai government has not yet assigned an official name - although the colonists call it ia'Maura, or "little sister" because of its similarity to their homeworld, ia'Vei. The natives themselves mostly just call it "home"; the eumin trapped in the bubble at the bottom of the ocean call it Hell.
The qii are the native species. They appear (at least superficially) to be an alien of herbivorous descent; they have flattish faces with prominent nostrils and leaf-shaped mobile ears, and small, peg-like teeth. They range in height from approx 4-6 feet as adults. Their legs are plantigrade (i.e. they walk with the sole of the foot flat to the ground) although an "extra" joint is present in all the limbs, so visually there is the implication of a digitigrade mode of locomotion. Their skin is mostly hairless, and they lack tails.
Socially, they are a civilised but not particularly technologically advanced people;
The eumin present on CW-13.4-923 are the former colonists, who found the planet a century or so prior to the Kiravai laying claim to it. The few Eumin who remain on the world live in a "Bubble city" at the bottom of the ocean floor, a mile or two down. They are what remains of a science colony, prospecting for new minerals, new biologicals.
