[@AdobeFlash] yeah that sounds great. Mithias might have tried to infiltrate a meeting or something, or maybe he was an invited participant? He'd probably have to had passed as human. Maybe... Atlas found out Mithias was also a vampire when he was trying to hide it?

Mithias might have infiltrated some occult meeting to learn more about magic, and sensed another vampire. During an occult mishap, the entire mortal population of the club is killed, so Atlas and Mitty see each other, get into a conversation, and leave on a somewhat friendly note?
