News from the official Mythos website:

As some of you have already notice, we've begun our Mythos Closed Beta test! We'll be slowly ramping it up again, making new builds, and basically re-entering the public testing phase of Mythos. Log on, make characters, report bugs, and lets get this thing started again! I'd like to extend a welcome back to all our Alpha testers, and also welcome all the new people who will make up the Mythos community. This is going to be a lot of fun!
