I want to say it's a coincidence caused by the same team having to come up with dozens of designs and just having some simple things repeat... but that might just be because I was so sure that the Sharlayan Sage symbol was mirrored and rotated and had an eye put at its center to become the Scions of the Seventh Dawn symbol, and it was all a coincidence, lol.

I ... will keep an eye out, though. Darksteelfoil hat-y? Yes. Interesting? Also yes.
