Lunarians are the people of the Moon. whether they are humans or something unique is dubious, however most Lunarians see "Lunarian" as either a race, ethnicity, or nationality, rather than a species.

when referred to as a unique species, they're Homo lunaris or Homo sapiens lunaris. they're more commonly seen as Variant Humans. the first Lunarians are called người Nhất, and all the Lunarians who have come after that original group are called người Hai. (người Sau is used on occasion, but is significantly less common than Hai.)
