Underland: A Deep Dungeon Delve

I’m partway through "Underland: A Deep Time Journey," a 2019 book by Robert Macfarlane. The book is broadly about underground spaces, and the fascination they engender in us. The book’s potential application to fantasy TTRPGs and dungeons is so obvious that I have to imagine someone has written about Underland in the context of RPGs. But googling “RPG Underland” and similar terms didn’t produce any results, so on the off chance that I’m the first to notice this, I will share some interesting quotes from the book that are readily applicable to D&D-style RPG games.

On Walter Benjamin's unfinished Arcades Project:

It is clear that [Walter] Benjamin’s imagination was strongly drawn to enclosed and underground spaces: the warren of the covered ‘arcades’ themselves, as well as the caverns, crypts, wells and cells that existed beneath Paris. Taken together, these sunken spaces comprise what Benjamin called a ‘subterranean city’, shadow twin to the ‘upper world’, and dream-zone to its conscious mind. ‘Our waking existence is a land which, at certain hidden points, leads down into the underworld,’ he wrote, memorably: the realm from which dreams arise. All day long, suspecting nothing, we pass by these inconspicuous places, but no sooner has sleep come than we are eagerly groping our way back to lose ourselves in the dark corridors.

This is right down the middle of the lane for classic dungeon construction. The shadow twin? The dream-zone? Sounds like the mythic underworld to me. I’ve added the Arcades Project to my reading list to see how much more the source text supports classic RPG exploration.

On the quarries underneath Paris:

For centuries, quarrying was ill-regulated and largely unmapped. Then in the mid eighteenth century, the extensive undermining began to have consequences for the upper city, causing subsidence sinkholes known as fontis that were reputed to be of diabolic origin. The quarry voids had begun to migrate to the surface; the under-city had begun to consume its twin. In 1774 a fonti engulfed, in a matter of seconds, pavements, houses, horses, carts and people. The site of the sinkhole was, of all places, the Rue d’Enfer – the Street of Hell. Several minor cave-ins followed, and panic spread in the city at the unknown extent of the invisible danger. Louis XVI responded shortly after his accession by creating an inspection unit for the ‘Quarries Below Paris and Surrounding Plains’, headed by a general inspector called Charles-Axel Guillaumot, and tasked with regulating the quarries for the purposes of public safety. It was Guillaumot who initiated the first mapping of the void network, with a view to consolidating existing spaces and regulating further quarrying activities.

If you showed me this excerpt without context, I would assume it was fictional content for a novel, RPG, or video game. It already sounds like a scenario that might show up in, say, Miseries & Misfortunes. Just consider how many gameable elements we can draw from the above paragraph alone: 

• Sinkholes, a fascinating, scary, and under-utilized phenomena.
• The sudden immersion of the surface/normal/waking world into the subsurface/abnormal/dreaming world (“a city block has sunk, can you lead people to safety?”)
• “Reputed to be of diabolic origin.” Great ambiguity. We can either treat this literally (malevolent intervention in the surface city) or figuratively (peoples’ misunderstanding of what causes the sinkholes leads them to attribute it to the supernatural).
• “The Street of Hell” and “the invisible danger.” No elaboration needed.
• An inspection unit. This is another great hook to adventure. The PCs are explicitly assigned the duty of mapping the “void network.”
• Yes, it is that Louis XVI, so on top of everything else, this is an urban scenario percolating within the prelude to the most famous revolution in world history. 

The book goes on to detail the various uses of the catacombs over time:

The deposition of bones into the catacombs continued over the course of the nineteenth century, but quarrying dwindled away as the best limestone deposits became worked out. From the 1820s the quarry voids were put to a new use as mushroom fields: damp and dark, they provided the perfect growing spaces for fungi, which sprouted from rows of horse manure. Adaptable quarrymen made a career move into mushroom farming, and a subterranean Horticultural Society of Paris was founded, its first president being a former general inspector of the mines. By 1940 there were some 2,000 mushroom farmers working underneath Paris. During the Second World War the French Resistance retreated into sections of the tunnels in the months following occupation. So did civilians during air raids – and so, too, did Vichy and Wehrmacht officers, who constructed bombproof bunkers in the maze under the sixth arrondissement.

The abundance of gameable options here is comical:

• “The deposition of bones.” Yes. Catacombs and necropolises are obviously fruitful places for RPGs for any number of reasons, including the undead. All the more when they have multiple overlapping/conflicting uses.
• Mushroom fields. Again, this creates room for both classic monsters and unconventional “treasure” (be sure to have a “so you ate a random mushroom” table to roll on).
• “...its first president being a former general inspector of the mines.” Sounds like an adventurer who graduated to domain play.
• Factions in the dungeon. The resistance, civilians, Vichy, and Wehrmacht officers all going underground. If I had read this in the pages of a WW2 RPG, I would have thought it was cool, but a little unrealistic. Knowing that it is real provides some great fuel for games of all kind (and this wasn’t even the only urban space where this kind of thing happened during World War 2).

I’ve been reading bits of Underland between time with other books, so I haven’t finished it yet. I’ll follow up this post with another one if I find other interesting excerpts.
