When the question of the key comes up, she seems, somehow, as puzzled as anyone else. She draws out the steel rod from where it hides in her armor and holds it aloft. It doesn't really look like a key, just a rod some seven inches long, enscribed with certh she cannot read. If it hadn't been seen unlocking the colony's doors, one would think it an ornament, or perhaps an enchanted item of unknown purpose, but a key? Not without the customary handle at one end, and teeth at the other. She freely offers it to Blain, and anyone else who wishes to study it.
"I did not mention it because I knew not what it was, other than that it might be a means of opening something in the colony, and perhaps not even that," she explains. "The Wizard told me that he'd found it in the treasuries and thought it could have something to do with the colony, but even he did not know for sure. He bade me to offer it to the company when it were needed, but when I found you, the door was already open, and we did not find anything else it might unlock. And then..." Her countenance darkens as she falls silent in memories of drowning, defeat, humiliation, the cold of the grave. She snaps her eyes back into a focus. She says nothing of this, but all who were there to see it must know what is in her thoughts. "And after that, we were running. The first time it was needful, there was no time to discuss it, so I took what action I thought would serve the company best, and put it to use. We are blessed by the Wizard's wisdom that it was able to save us when we most needed it."
When everyone has seen the key who wishes to, she asks to have it returned to her, that she can return it to Saruman.
