How do Ven and his friends get from the Inn to the ocean in their attempt to save Ida?

The foursome run to the stables and borrow a horse and wagon from Cadwalder, in order to get to town and to the sea. Saeli is able to tell the horses where to go, and Murphy agrees to inform McLean of their plans if Ven agrees to being him a treat. At the gate to the city, Clem at first tries to reason with the guard, but when that fails, Saeli uses vines to entwine him.
