The Raen army quickly spread themselves, making sure to cover every viable exit from the central Glade. In fact they had even moved faster to siege the central Glade than they had to get to the field of the battle the first time. After the situation with the traps, more than a few of the Raens present wanted pay back.
So they had quickly surrounded the central Glade. For Cole though, he too was looking forward to bringing the central Glade into the fold and consolidating his power and authority over the Great valley. And once that has been accomplished, they would have every piece of land around them fully under their control.
