[ The person emerging from the darkness seems harmless enough-- Tired at the very least. She's sporting impressive dark circles under her eyes and carrying a couple books she's taken from the other side of the room. She briefly pause at the sight of the riffle.

[ Strangely enough, she doesn't seem too bothered at the prospect of being shot down. And in all fairness, comparatively to what the captives have been going through, being killed seems like a kind fate. She's been here long enough to piece together what had happened in this room and subsequently lose all hope to find anyone alive in this place.
