Dungeons & Baubles

The Revenger Trilogy is a series of science fiction novels by Alastair Reynolds. In a future millions of years hence, there is a spacefaring civilization amid ancient habitats that form a Dyson Swarm around the sun. Sisters Adrana and Arafura Ness flee their stifling life of wealth to become "bone readers" aboard a solar sail privateer searching for ancient, technological artifacts. 

Things don't go simply easily, as their ship falls prey to the infamous pirate, Bosa Sennen. From that encounter, the sisters are propelled into danger and more adventure than they ever wanted, and ultimately, the deep mysteries of their civilization.

The books are highly enjoyable in their own right, and the world would make a great rpg setting, but beyond that, I think that, in part, they are excellent inspiration for dungeoncrawling sort of adventure in any setting.

Working Class Treasure Hunters

The "dying in holes in the ground" aspect of low-level D&D beloved by old school play is poorly represented in the fiction of Appendix N, but the Revenger series very much portrays this sort of thing. Privateer crews are typically hard luck folks with scars, missing limbs, and stories of former comrades lost in the pursuit of that elusive big score. Such crewmembers have specialties: readers, openers, appraisers, to be efficient in the unglamorous work of seeking out treasures. These treasures are often strange--not as strange as things brought from the Zone in Roadside Picnic--but things that the current civilization can't make nor sometimes even guess their intended purpose. In these novels, these items often function as low level, utilitarian magic items.

Dungeon Lore

Having good intelligence on Baubles is a crucial part of "cracking" them. Baubles are surrounded by force fields that only open at certain times and openers rely on information from other privateers and their own readings and calculations to augur the time and duration of openings. Acquired maps are also essential for efficient and profitable "delves." Baubles have colorful names like His Foulness, the Cuckoo, Wedza's Eye, and the Yellow Jester, and their own internal arrangements and hazards.

Creative Uses

I mentioned before items brought out of Baubles, well their are obvious things of value like quoins (their unit of money), robots, or energy weapons, but also things that can be used less obviously in the privateers life. Bosa Sennen's dread ship has near invisible black sails made from catch cloth found in Baubles: a material that responds to some unknown and otherwise undetected emanation of the sun. Privateers prize even small peices of look stone, a strange glass-like substance that when peered through allows the ability to see through solid object. 

The Revenger series presents, in part, professional treasure hunters focused on resource-oriented and practical aspects of their trade. There are few "monsters" presented--just the pirates and one other threat I won't give away. The dangers are traps or merely hazardous aspects of the environment.  These aspects make more solid inspirations for elements of D&D that don't usually get much of a showcase in fiction.
