You gotta @Mention me.
@Mischief: Welcome, new friend.
As Total has said, you happened to have joined right during an event.
If you participate in the official Hide and Shriek investigation threads, you'll receive a different event item for each one, as well as some event currency.
I see you've already started settling in with an art gallery. Very cool!
It's nice to see a rendition of Loki that isn't just Tom Hiddleston.
Edit: Pfthaha, I just realized I sound like some kind of robot with this welcome.
Welome! Very cool! Beep boop.
