Vaporian is a xenogender from the Element System. It is a combination of the masculine element fervian (fire), and the feminine element eluvian (water), and is represented by the element of vapor.
History
Vaporian 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 grey and white, the colors of vapor, with a diamond in the center, representing the eluvian and fervian triangles stuck together.
