A Sigil that is commonly used by Etrian, on certain clothing, to represent his tie to the Kaliuga clan. It was already been featured in this picture and this one too.

This was a project I did in school, while taking a Graphic Design class. The base image originated from a culture I can't recall, but I decided to make use of it in my expanded universe, in stories and Etrian's numerous outfits. :D
