Wow, that girl has the doomiest doom aura Adam has ever felt radiating off someone who didn't have black fingernails. Adam wants someone that scary on his side, if it's possible to arrange that, so he approaches her.
"Hi, I'm Adam."
Adam chuckles. "Pleasure swapping with you as well! I'm in 629B, if you want to trade again when I've developed more spells."
"I think a lot of people swap things they get out of the void, too."
"Mm-hm. Ta." She does not know how to end a conversation politely so she turns and walks away into the crowd at random.
