Use this beautiful tattoo to showcase your part in the Assassin Order. There have been multiple renditions of the insignia throughout the game series, so to add a little more flair the version from the Italian Renaissance or the Babylonian Assassins could be done instead.
"The symbol that you sought and found... It is a mark of courage and honor, yes. But it promises pain and loss as well."
--Oiá:ner, speaking of the Insignia
