Here is what I have learned from comments, none has been confirmed. Each user can create a circle. Looks like you give it a name and password. Anyone who gets the password can join your circle. Anyone in the circle can disband it. It seems like you can join multiple circles, but you can only make one.
When you first put in the password to join a circle it gives you a choice to join or betray. It seems that once you have joined, your decision is made (though since you know the password, it would be easy to get someone else to betray).
Make one, only invite those you trust. If you care to trust a fellow knight ill gladly uphold your circle.

The April knights are active and are exploring the options. I’d recommend holding off for now.
Anyone wanting an extra member, I'm a knight happy to help grow your circle
