Name of the Clan

I thought of the "Circle of Demetia"

OR

the "Circle of Emrys" (Emrys being the other name of Merlin, which would be the mysterious creature under the cloak)

OR

Something with "Avalon" in it.

What do you reckon?

Hey !
I like the second one, but i will suggest that we all look for some ideas and when we will be on the camp we could organize a vote with the kids in order the directly involve them into the clan
