The Chemistry of Dungeons, or: help me I need dungeons and I just have an old organic chemistry book. Also, writing to Gary.

I’m going to write possibly the nerdiest post ever.

Suppose your players left the village of Somewhere Away and decided to pursue the Dodgy Villager That Secretly Is A Pawn Of The Villain: you need a dungeon where the DVTSIAPOTV and his boss can meet.

And you just have a chemistry book: opening the book for inspiration, you see  meaningless chemichy blabber about lignin. Wood and paper are made of this stuff. What if you could turn all that drivel that allows us to keep our lifestyles possible in a fantastic adventuring locale? Behold lignin:

Instant Dungeon! And a big one!

First of all, the theme: lignin is about wood or paper, so it could be something like a dungeon full of constructs and animated objects, or full of books, or a library, or a magical miniature castle made of paper that you can enter if you touch, or a network of treehouses.

Now, what do you do with this map? how do you read it?


And requires zero knowledge of chemistry:

  • the lines (bonds) that links atoms above are CORRIDORS: 3 in 10 are either hidden, closed by a locked door, closed by a door. To determine which room has the key, roll a dice on the map and that’s the room: It can be either hidden or held by a monster (50%).
  • C means CARBON and Carbons are rooms with four exits, or CROSSROADS. Roll content as per empty room. You should also come up with a small random monster table adequate to the location (6 entries are good, too many seem really random and nonspecific).
  • O means OXYGEN or OBSTACLE. It can be a room with some nastyness: usually to stop intruders; traps, guardian monsters, locked door, trapped locked room with monsters, or simply a cave in that makes the passage unsuitable. Oxygens have 2 exits, like a passage. If an oxygen is lonely next to a carbon you have a DOUBLE BOND (described later).
  • H means HYDROGEN, and hydrogens are room with a single exit. They contain stuff and nasties.
  • N means NITROGEN and also NETWORK: the (usually three) rooms connected to it form some kind of small cluster of logically connected rooms, like a guardpost with barracks, studio, den or apartment. Dress accordingly, and use for important stuff peculiar to the dungeon.
  • DOUBLE BONDS happen when you count the exits between rooms and some are missing, while in some graphs are displayed as a double line. Two distinct passages link the two rooms, usually one of them is secret/locked/hidden/trapped, or one of the two rooms is split into two parts by a chasm, bars or whatever you prefer. See it as an occasion for interesting tactical choices in combat or exploration. Also, read MinnenRatta’s comment below.
  • If you have other letters, throw in random stuff according to the atom, or not if you can’t be bothered: it’s just there to kickstart your imagination and its deconstruction it’s only for your benefit. If you see strange lines connecting stuff, treat as special/trapped/secret passages. If you see, like in the picture below,  three/four lines connecting, it’s a CARBON/CROSSROAD. If there’s a bend that bend is a carbon crossroad that has two hydrogen rooms next to it (unless double bounds are present, reducing the number of hydrogen/rooms adjacent). The bit to the right is a long corridor with 10 rooms spread between the two sides, and a room at the end. I guess the below dungeon is good for a drug smuggling hideout.

  • To finish, sprinkle secret doors that link more or less remote areas of the dungeon. And pick a number of exits.
  • Of course you might expand the meanings above to elements of the same groups. Halogens such as Fluorine and Clorine are EXTREMELY NASTY ROOMS, chalcogens like Oxygen ans Sulfur are obstacles and so on.

DONE. Ok, my nerd club membership has been renewed for the next 15 years or so.

And now the occasional tiny letter to Gary.

Hello Gary,

I know you’re dead and you can’t read me me. Also I guess you can’t read wordpress. I guess this makes me look a bit stupid, or romantic. Well, I wanted to thank you post mortem for having published my favourite game. I never met you and I can’t say much about you, but thanks for having given me such an empowering hobby.

That’s it. Ok, enough time spent writing to corpses buried thousands of miles away. Back to science!

  1. You know, I was looking for some ideas to help inspire me to create a dungeon map, and this is a fun way of doing it. Thanks 🙂 I wonder what else we can use to create random maps…

  2. Methinks that all those hexagons you get in biochemistry deserve special treatment rather than becoming just circular passages with stellated rooms. Those are open spaces (courtyards in castles, caverns or huge rooms underground) with double bonds being balconies or ledges which may hold ranged enemies. When a bond radiates from a balcony then the balcony is in fact a stair leading from the courtyard/cave to the radiating corridor on another level.
    Notice how this keeps with the idea that double bonds are tactically meaningful, but ledges, balconies and stairs can be disseminated without forcing a style, while chasms everywhere tend to turn every dungeon in Moria revisited.
    When I want Moria then I would map chasms to CHasms 🙂 With the multiplicity of H being the depth of the CHasm. Of course HC is not a chasm, it must be strictly a CH.
    All of this is so funny, great idea!
