Guild Wars 2

So my friend and I put together a set of 5 coins for our guild. The front is the guild, guild tag, and stylized guild symbol. The back is a representation of one of the five races. I want to change the Norn symbol but I’m not sure what it should be.

Talked to my artist today and we are looking at turning these into metal challenge coins. Maybe make a set with the A-Net logo on it s an easy example of what we can do and how we can customize them.
