Hey all! I’m looking to get a Sith tattoo and I came across this icon (the symbol at the top)and I’m not sure where it comes (if its even legit) or what timeline it may come from. Can anyone help? I can’t remember where I found it but this is more or less what I’m looking to do. I drew this up earlier today but I couldn’t find that symbol anywhere.
