Harenian is a xenogender from the Element System. It is a combination of the neutral element tellusian (earth), and the undefined element ventulian (air), and is represented by the element of sand.
History
Harenian was first known to be coined on January 14th, 2018, along with the flag[1], but it was likely coined earlier than that on a Google spreadsheet[2].
Flag
The flag's colors are orange and yellow, the colors of sand, with a diamond in the center, representing the tellusian and ventulian triangles stuck together.
Etymology
The word harenian comes from the Latin word harena, meaning "sand"[3].
