Ferrian

Ferrian is a xenogender from the Element System. It is a combination of the masculine element fervian (fire), and the neutral element tellusian (earth), and is represented by the element of metal.

History
Ferrian was first known to be coined on January 14th, 2018, along with the flag, but it was likely coined earlier than that on a Google spreadsheet.

Flag
The flag's colors are orange and grey, likely the colors of copper and iron, with a diamond in the center, representing the fervian and tellusian triangles stuck together.

Etymology
The word ferrian comes from the Latin word ferrum, meaning "iron".
