Can we throw out a bunch of suggestions or just one for the sake of the contest? I find guild naming isn't really that objective so it's hard to do from the outside. You want it to fit the brand identity and nature of the group and it's kind of an NP problem where its hard to know the answer offhand but once you read it it has a nice ring to it and you just know it fits. I think the best way to do this is to just throw out a few suggestions so you can get something that matches the "Je ne sais quoi"
