When you're used to being not just the shortest person in the room, but the shortest by a measure of about two feet, you notice someone else your size very quickly. Apparently the venue has similar ideas about how they should be dressed, as well. Barcus is in a silver mouse mask, with a matching baroque suit that's a bit tighter on him than he'd normally choose to wear, and a long tail looped through the belt. So, mouse, meet deer?

Being the same size is probably a foolish reason to seek someone out, but it's a party after all. You don't have to have a reason to talk to other people.

He slips through the crowd, irresistibly curious. Hard to tell behind the masks whether he's looking at a halfling or a gnome, or maybe some entirely different entity that he's never encountered before, but he goes up to the stranger regardless. "Hello! I...hm. You must be a new arrival. The only other person my height I've met here is...no longer here, as far as I can tell."
