In my travels across Skyrim, I've encountered a handful of items which possess particular value. A Dwemer Puzzle Cube here, a Jeweled Candlestick there… normally such things are hard to find buyers for, but Delvin's always been there to take them off my hands.
Unfortunately, he also plays his cards close to his chest and doesn't seem inclined to simply ask for particular items, seeming to prefer I stumble across them naturally. I, however, do not. I intend to be running this merry band of thieves soon and want a well-stocked trophy case.
What, and where, are all the special items Delvin is seeking?
