A small shop with an unassuming front, Darkhaven is exactly as full of books as the front window indicates. That is, it's packed with them, although they are all arranged quite neatly by alphabetical order and subject. Ushahin bought the store from a retiring citizen, so the assortment of books is rather motley. In short, it is a browser's paradise and possibly the bane of anyone looking for a specific book. Organizing is a constant battle. There is a small reading corner in the shop, basically a few old overstuffed chairs and some cushions on the floor, and the Doctor doesn't mind people coming by just to read, as long as they're careful with the books. The atmosphere of the shop is generally cozy and welcoming.

There's also a small display of Hugo's clockwork things that he still has around even if Hugo's left. As Ushahin used to keep the shop, there will also be a small cache of well-kept rarities, first editions and other things (not necessarily books) not easily available in Asgard. Some of them came from the shop, but many have come from trips to Utgard. While the prices on the regular stock are quite reasonable, the rarities are more expensive.

Ushahin did work on making some 'friends' of only slightly questionable quality in Utgard, who found and sold him interesting gewgaws of varying usefulness. They are not be things that break the Asgard tech level, but instead its culture level--things from places that aren't grey, where people are actively creating. None of the items themselves will be illegal in any way, but don't ask how they got there or where they came from.

And basically the Doctor will keep this up to the best of his abilities (aside from the questionable bit). Although probably a little more sloppily, aside from the order to the books. That is important.
