If I do not see anything as the group moves up, Tork is going to be ready for a fight since this looks like a perfict place for a ambush. Shadows start moving up around Tork then he just disappears from sight as the party walks closer to the moathouse.
He gets in his Child of Shadows Stance then hide from plain sight.
