the Anku (Delearus ploutonus) are a race of small, humanoid aliens living on Pluto. they, along with the Lungores and Xali, make up the bulk of intelligent life on the planetoid.
they are very distantly related to the Manbu (Delearus kythereus) on Venus. they come in a multitude of colors, like pink, magenta, purple, periwinkle, and blue.
they generally call themselves some variation of an-quu, meaning "common/abundant folk", however an-paa'lung "people of Paa'lung (Pluto)" and the dated kxii-qx̣ii (exact meaning unknown) are found as well. while they are from the Meng-p'o Macula region, like their name suggests, they are quite abundant. they can be found across Pluto and one of its moons, Charon. (Charon Anku are a unique gray color!)
while Neptunian propaganda has painted the Anku as a barbaric race, they're generally quite docile as long as you leave them alone. they have lived in peace with the Lungores and Xali for nearly a million years, and although the three races live in their own seperate communities, they will all come together to pool resources during disasters. they are also quite friendly to Lunarians and will pay extra attention to their speech (since they don't have gills, they cannot properly speak most dialects of Ankuese).
Anku are bidirectional hermaphrodites. nearly all Anku are born male and change sexes over time.
despite the caste, most traditional Anku communities are communal. individual land ownership was not common prior to the Neptunian apartheid.
most Anku don't have surnames. typically only high caste Anku (u-qx̣őng and ebeğing-ji) have surnames; Anku who have surnames use the Eastern naming order, e.g. Aq'oqx̣őngaw'yngi U'fin (surname Aq'oqx̣őngaw'yngi, given name U'fin).
