The back of Sionn's garments were fairly intact. She could tear off a substantion portion of the fabric to use as a makeshift loincloth. Furthermore, her shirt could be tied up to cover her breasts, with a knot where it had been ripped in the middle. It would barely cover her breasts, and thus wouldn't provide any warmth, but it would deal with the modesty issue.<br/><br/>As for the climb, it was an easy one for an experienced individual such as Sionn. Looking out of the hatch, she found herself in what appeared to be an immense cavern with an underground body of water, dimly lit from some kind of fungus on the walls and ceiling. She was on the shore of this underground lake, that stretched as far as the faint light allowed her to see. In the other direction there were three separate tunnels, leading off in what appeared to be somewhat different directions, although one could not tell if any of them were leading to higher ground.
