As I see it:
Group One (Scyld and Linduial) has been located for the climax of the story. I hope to post for Eodwine soon, about the chase, but it looks like Group Two (Sorn and Gurth) needs to get some attention before Group Three (Eodwine & company) catch up .... or arrive moments after the double death...... And Group Four (Garstan and Herb Maester
) must wait.
So that means I'm waiting for
Tara or
Anguirel before I post.
