So I love watching YouTube videos. Primarily because they can cover a wide variety of interesting subjects that you won’t usually find in regular educational (or semi-educational) channels. I’ve been able to find interesting looks at how common people lived and ate not only in medieval times, but in the 1920’s and 30’s (which make for interesting game fodder for gangster type role playing games). We all have a general idea how Mob leaders and the royalty lived by the various movies and glamorous stories. But informative videos talking about the other side of the coin for various eras can help when adding atmosphere to different RPGs in different eras.

YouTube has an interesting algorithm on suggesting other possible videos that may be of interest. Sometimes it works, and sometimes it doesn’t (I won’t go into details but I wish that the YT apps on my TV had a way to give a “not interested” without having to go to the video itself).

One recent suggestion from YouTube was “Digging a Secret Tunnel” by a British content provider using the handle “colinfurze”. Apparently he’s been digging a secret tunnel that connects his house to his workshop and then to a backyard underground bunker for the past three years. Note: The video linked above is part six of the series, but it was the first one I had watched and inspired me to create this blog post. Also a warning, Colin comes across a little like a used car salesman in his enthusiasm. But don’t let that bug you, the video was quite interesting despite his almost game show host like quality.

The first reason that I clicked on the video was because I was one of the many young boys growing up who had the idea of making a secret tunnel in his basement as a means to covertly get out of the house. Luckily my parents never found out about me trying to cut through the walls in our home. And I didn’t get very far because the house was very well built. Colin’s video showed the amount of preparation and effort that was being put into the tunnel project. It was being built under his house, driveway and workshop before it made it to the bunker. You don’t want the ground sinking underneath those items. So it had to be re-enforced to hold the weight above them. They had to get the large amount of dirt and rocks hauled out through a 5×5 hatch that was built into the workshop. Colin claimed in the video that he is making the tunnel without the knowledge of his neighbors. Reading the comments was interesting (avoid the spambots) with posts from mining engineers and other interested parties.

The second thing that caught my attention wasn’t with the tunnel itself, but my thoughts that came up while watching the video. How many times have we seen a villain’s secret tunnel in an espionage movie? The image I used at the top of this blog came from the spy-fi video game “No One Lives Forever” and I remember seeing this scene thinking “who built this?” and “How did they keep it a secret?” As a gamer, I also thought about the various dungeons that our Dungeons and Dragons characters have crawled through. Quite a few times they were 10×10 tunnels underground occupied by various Orcs, Gelatinous Cubes and other dangerous creatures. While someone may have drawn the straight line on grid paper, in the game world someone would have had to dig it out, build supports and haul away the rock. Why was this built this way?

I eventually had a bunch of thoughts in my head that I knew I had to put it down as a blog post. I watched a really good video about creating a dungeon for D&D which went briefly into the whys and hows (and I learned quite a bit from the video). But it didn’t really get to the nitty gritty for me.

So why would a tunnel (secret or not) be built with the cost and effort involved? I think it comes down to several reasons. The first one that comes to mind is wealth. The tunnels are built as part of a mine trying to extract various ores and precious gems. While these may not be secret at the start (unless the digger wanted to keep others from getting to his prize) they could easily become forgotten. Just finding out which mine a highly prized gem used in an ancient crown came from could be the start of a quest all on it’s own. These mines could have been built by dwarves or other subterranean races. Mines were featured quite a bit in several westerns. Every once in a while the news reports about another soul lost while trying to explore a closed up mine or a murder victim being thrown down a mine shaft.

Another reason that a tunnel could be built is for transportation. Going over a mountain or across the English Channel represents a physical barrier. If you could tunnel under that barrier, you can make transportation much easier. Again, most of these would be known (at the start). However there have been smuggling tunnels built to avoid border patrols. The movie “The Great Escape” detailed the efforts of prisoners attempting to tunnel their way to freedom from a Nazi POW camp. This movie would also be inspirational about how to hide the tunnel and dispose of the debris needing to be dispersed all while trying to keep the tunnel from collapsing on them. When I visited the Black Canyon of the Gunnison National Park in 2019, I learned about the railways and water tunnels and how they were built. They were built in a time before OSHA and safety guidelines. So corporations could hire workers to quickly dig, and if a worker was injured, they would hire the next guy to step up and replace them. This allowed them to build these tunnels quickly at the cost of human lives.

Housing and storage is another reason to build tunnels. I recall watching documentaries about World War II and how residents of some towns escaped into tunnels under the city to escape bombing raids. Repurposing tunnels from another use has allowed underground survival dwellings to be built. In Utah, the LDS Church stores massive amounts of genealogical records in an underground vault in the Wasatch mountains. In Norway, the Svalbard Global Seed Vault preserves over a million seed samples underground in a former coal mine. Both locations could make for interesting modern day missions in an RPG. On the fantasy side, how many times have we heard about massive underground cities used by the Dwarves and the Drow. Tunnels would connect them all to each other and to the surface.

The last reason may sound weird, but I think is valid. Tunnels could be built for a sense of vanity. A cult, probably using cultists or slaves to dig, could build secret tunnels in order to hide their temples of worship. The image that I used above is a tunnel under a Swiss Alp chalet as seen in the video game No One Lives Forever. In the second video game of this series a very interesting quote came up. “Why do you think we have our headquarters in underground caverns? It’d be a lot cheaper and more convenient to lease an office building, but then you get potential clients who don’t think you’re evil enough for the really high profile operations.” If you look at movies like the various James Bond entries, the Flint and the Matt Helm movies all the way up to the Austin Powers series, they all made the secret underground lair look cool.

So Game Masters, think about the tunnels that you use in your games. Sure they are easy to draw on graph paper, but how did they get there? What was the cost to build these tunnels? How did they become secret? A king killing the slaves that built the secret tunnels may become the avenging undead monsters encountered by the players. A missing handyman may lead to the clue that the agents are needing to find the bad guy’s underground lair. Those lines on the map may look cool, but they hide much more than the treasure the adventurers are trying to find. They hide a possible story.

(looking at the wall on the side of my office) “I wonder if the wife would notice if I put in a secret tunnel?”
