This is the kind of detective work I love AR for, lol.

A stroll through their bestiary reveals a whole lot of festival and downtime familiars, and not much else. That's a really suspicious pattern for someone who joined like a week ago. One of their dragons is wearing a Sunchaser too... I'm not gonna report because I don't think it's a big deal, but it's fun to spot a person like this in the wild.
