You haven't missed much, to be honest, we're just starting to get the characters acquainted.

The RP opened with a group of 12 Wanderers attacking Ashlynn (for currently unknown reasons) but she was rescued by a few students and the Guardians. They did a lot of damage before leaving and so they've been established as the main threat. Some of the students are interested in researching and finding out who they are etc. That's about the only main plot point at the moment as the rest is just random character development. :)
