Caligian is a combined gender element from the element system. It is combination of the feminine element, eluvian (water) and the undefined element, ventulian (air), and is represented by the element of mist. One whose gender element is a combination of feminine and undefined would be caligian. The noun form of the word is caligi (ex: I am caligi).
History
Caligian was first known to be coined on January 14, 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 light purple and dark purple- not really the colors of mist, but it was likely chosen so it's not too similar to the vaporian flag. There is a diamond in the center, representing two triangles together.
Etymology
The word caligian comes from the Latin word caligo, meaning "darkness", "mist", or "fog"[3].
