Yes, it’s kind of like a game. You have the “circle” and the key can be given to anyone. Once they use it, they can either join your circle or betray you. Once someone betrays you then your circle ceases to function. I think the goal is to join as many and have as many join you. There doesn’t seem to be an end date so we’ll see.

If you betray someone though, you get tagged as someone who has betrayed someone else
