Mysti didn't move from her place at first, watching the Mercykillers and whomever else decend upon the ruins and ashes of Rhaunades's Library. What a shame.
Perhaps she should just let the Mercykillers do all of the dirty work - and then when they catch the guy - or girl - or it - they can just bring the perpetrator to the Harmonium. It was dirty in there. And ashy. No doubt it was that nasty wet ash, too, after gods knew how many buckets of water were tossed in there. Water plus ash meant wading through something with the consistancy of glue.
Normally she didn't walk around the city wearing anything that connected her with the Harmonium - but in this case - she affixed the badge to her leathers so no one chased her out of there. After all, it looked as if she were the only one of the Harmonium present. For now, at least. Once that was done, she slipped into the ruins as soundlessly - and as unobtrusively - as dhampirically possible.
So ... arson. She knew as much about fire as she did about Loviatar's bedroom. Which was to say - nothing. At all. But she wasn't really concerned with that. If one wanted to know the perpetrator - the big question was always: Why.
"It always came down to why." Mysti said those words between breaths -- barely a whisper.
"Once the 'why' was answered, the brute responsible would light up like a torch in a cave. Why did you burn the place ... which brings us to the 'what.' Just what were you trying to hide."
What was this library all about? What kind of knowledge did it contain? Was it heavy in magical lore? Perhaps -- forbidden lore, yes? And forbidden lore would not be left out in plain view now -- would it. Of course not. And that meant -- secrets. Hidden rooms. Concealed cellars. Perhaps there was an entire network of caves and catacombs beneath this place. Rooms yet to be discovered that even a fire may not reveal ...
Mysti pushed clumps of ash aside with her unpolished boot until the stonework beneath was revealed. This ought to be easy. Ash should accumulate within the seams of any trap doors in the floor which, otherwise, would have been almost undetectable. But just to make sure, she unlimbered her bow and tapped it against the floor. Tap. Tap. Half a step. Tap. Tap. When she arrived at a wall, her opposite hand meticulously knocked the metal pommel of a throwing dagger against it, her ear pressed against the cold stone causing her skin to feel clammy.
Her work was slow -- but thorough -- the kind of patience that only a being with a very long life could have ever tolerated.
"There better be something here," she growled -- and continued checking.

A few ashes caught in her throat as she moved them around, their dark little flakes swirling upwards in the warm eddies leftover from the fire. And it stank ... like ... ashes. There had best be something here ...

((DC 15: Pass. Your investigation of the library finds a metal basket containing the charred remains of some fruit. Apples, specifically. Maybe the wizard just liked apples, but it's not something commonly found in a library itself, moreso on display on a foyer or in a kitchen.))
