With a few days in dock and having read everything in your personal book collection, you decide to head down to the Library Vaults of the Ignis in search of new material to read. You gather up your usual accessories, including the Scathanna and your mapslate, and set off.

Three-quarters of an hour later you are wandering through the stacks, browsing at random. You could try searching through the index, but you don't really have any idea what you are looking for. New reading material, sure. And there are more than enough books in plenty of different genres, styles, and authors to keep you from getting bored anytime soon.

But unlike the Library Vaults, your personal quarters don't have near enough room to store all the books you might want. You'll have to settle for bringing a selection of them back to your rooms to read through at your leisure before returning and exchanging them for the next set.

You continue to wander aimlessly about for a half-hour, picking books here and there, reading a page or two, putting it back. Your aimless meandering draws you back to the carols, the reading area. No one is back here, and there is a fine layer of dust on top of the desks and chairs. Not many people use this area, and no one has come through here recently.

Which makes the skeleton key left on one of the desks all the more interesting. Made of brass, it sits on the corner of one desk. You look around the Library vault. No one is in sight, and the only disturbances in the area can be attributed to your passage. You don't recall a locked door or container in the Library, so you stand there for a moment and think it over. Something is bugging you about this key. Something is off about it.

There is almost no dust on they key. It's the same amount as has settled on the desk, but there isn't much. You check an adjacent desk: the dust is much deeper. You return the the key and study it some more. Nothing else appears off about it. You ponder over the facts that you do have. This desk and they key on it is covered in less dust. Therefore, the desk was last used more recently than its fellows. The key was left behind when the desk was last used, and has been gathering dust at the same rate as the desk. You take a quick pace about the Library vault, but once again find no door or container that the key might fit into.
