Climb the ivy. Take the indirect approach.

You have never turned away from a stroke of good fortune. Something simple, even untrimmed foliage, could be the opportunity that gives you the upper hand. Grabbing a handful of the vegetation, you test its strength with a tug. You begin ascending the vines. The stone is slick with rain, and your equipment weighs you down. Every inch is a battle. A lesser hero would falter, but you continue to ascend. Towards the top, you dare a glance down. The plummeting depths of the high wall invoke a queasy sensation in your stomach. You continue carefully. You are ascending the tower now, rising above the castle for several stories. The vines continue up to the top.

Every reach of your arms pulls you one step closer. Now only a dozen feet from the window, you waft a unique smell. It is strong against the humid backdrop of the stormy night. A strange mixture of various spices, flowering vegetation, and bitter medicine... it reminds you of the old apothecaries who tended to your clan's wounded. Undeterred, you continue climbing. The glass window is propped ajar, faint torchlight percolates out. Your tired limbs continue, indefatigable, until you can just peak into the room. You still your breath, as you glance inside.

You see a large circular room, conforming to the edges of the tower. Inside is a living chamber, with comfortable carpet and nice wooden furnishings. Tall shelves and cabinets laden with glassware, books, and potted herbs are spread around the circumference of the room. Of particular note is the singular figure present in the room, straddling a pillow atop a lofty bed. The naked woman is engrossed in her activity. One hand runs through her disheveled auburn hair-- the other is placed strategically between her legs. Your lineage places an emphasis on purity, but you are no stranger what is happening. The woman breathes heavily, and is completely distracted. Based on her slim figure, you could probably take her in a fight. You notice a metal collar, made of engraved metal, around her neck.
