Leaving the arbour, you press on towards the outer wall of the arboretum. Through the dense foliage you can make out a narrow, arched doorway that leads to an open chamber. A stairway ascends to a parapeted walkway, at the end of which is a stone door. You are halfway up the stairs when the sound of a crossbow being cocked freezes your blood. To turn back now would be suicide; you grit your teeth and bound up the stairs as a hail of crossbow fire slams into the steps on either side of you.
