Exploring the Stygian Library as a Deckbuilding Game

I’m a fan of deckbuilders, whether as video games (Slay the Spire, Inscryption, and others) or physical games (Dominion, Star Realms, and many more). I’ve always wanted to see deckbuilding in TTRPGs, but if that game exists, I haven’t found it yet. The closest I know of is Meromorph’s Atma card-based RPG. That game does a nice job of using cards to inspire unexpected scenarios in a TTRPG format; but it’s not a deckbuilder.

I’ve mocked up several different TTRPG deckbuilding systems, but finding time to test games with other people has been a challenge. My players would be happy to test something if I asked them. But any such ask comes at the expense of the other TTRPGs and board games we could be playing when we get together. That's a high bar to clear.

While I still plan to look for opportunities to test multiplayer deckbuilder TTRPGs, I’ve also decided to test a solo deck builder concept. When I see an interesting question like this generate zero replies, it suggests to me that there is untapped space that game designers should explore.

We’re going to keep this as simple as possible by only introducing deckbuilding mechanics when we really need them. The theory is that it’s easier to start with a very simple system and confirm it works ats a basic resolution system before adding really creative tweaks and neat subsystems. In short, we want to create a game that works like other solo TTRPGs, but uses the randomness of card draw instead of dice for moment-to-moment action resolution, as well as the concepts of deckbuilding for both the progression and consequences of dungeon adventure.

As I learned when my Dungeon23 project lapsed, trying to do a big project with a single output is a recipe for disappointment. A project is more robust if it can serve multiple purposes, so I made a list.

  • Test if the deckbuilder model can work in a TTRPG
  • Get some use out of adventures and other products I have purchased, but rarely or never run
  • Experiment with solo RPGs
  • Produce some blog posts

That feels pretty good, right? Let’s go!

The Stygian Library

The Stygian Library (“TSL” for short hereon) by Emmy “Cavegirl” Allen is a great example of a “depth crawl,” along with their similarly structured adventure, the Gardens of Ynn. Players explore a place that is generated in part procedurally; there is no fixed dungeon map.

I have used TSL before as a prep tool for my D&D games, where quite a few sessions revolved around a Borges/Prachett-style arcane library occupying a liminal extradimensional space, which could be accessed from different places. But I have never used its procedural generation tools in-session, as they’re primarily designed to work. Time to change that.

“Put enough books in one place, and they distort the world. Space bends in on itself, forming a sort of wormhole, linking the library to other libraries likewise afflicted. The space between is a sort of pocket realm, budded off from reality, maintained by the sheer power of books.”

Emmy Allen, The Stygian Library

TSL is particularly well-suited to this project because the procedural generation of the dungeon makes it easier to run as a solo exercise. The dungeon is not a pre-defined space, so in using TSL for solo play, the player has to do less work to disentangle their player knowledge from their DM knowledge. 

Delve One

We begin in The City’s largest bookshop. Someone was murdered here last night. That’s unfortunate for Someone, but it is very fortunate for us, because we want to access the Stygian Library, and an entrance will only appear in a location that contains both (1. many books and (2. a recent death. Did the patron who hired us for this job simply take advantage of an accident that happened here? Or did they create the opportunity, by orchestrating a murrr-derrr? Best not to dwell on such questions.

Investigating the far corners of the bookstore, we find nothing on the first, second, third, or 13th search of the space. On the cusp of giving up, we find a barely visible door – not much more than a utility panel – hidden behind the heaviest shelves in the place. The key to the front door of the bookstore unlocks this lock as well, which makes no sense; a warning of what’s to come. We enter the Stygian Library.

Our Brave/Foolish Explorers

“Tell you what, if it's a high card, I'll tell you who I am. But if it's a low card, I'll tell you who you are. Is that a deal?”

Deadfall (1993)

I am using Knave 2 (“K2” henceforth) for character generation and ideas, due to its simplicity; general interoperability with other games; and its use of slots, which are a good analogue for cards. I have run quite a lot of the original Knave, but this will be my first genuine experiment with K2. Here is my PC, with no rerolls.

Felix Digham

  • A CON of 1 and a WIS of 2 (yes, I happened to roll the same results as the example in the K2 rules)
  • Level 1, 0 XP
  • 11 item slots
    • Bag of spice
    • Lamp oil
    • Knife
    • 2 rations
    • 50’ rope
    • 2 torches
    • Mail shirt
    • Helmet
    • War scythe (two-handed, d8 damage) (slot 1)
    • War scythe (slot 2)
    • Poison
    • 2 HP
    • Careers: Merchant, Thug
    • AP 2
    • AC 13
  • Personality: Truthful
  • Appearance: Rugged
  • Goal: Serve a deity
  • Assets: Smuggles goods
  • Liabilities: Known con artist
  • Possessions not carried
    • Strongbox (hidden in the bookstore and holding the below items)
    • Scales
    • 10 coins

I was a little confused at first by the merchant/thug and truthful/con artist dichotomies, but the assets and liabilities cleared that tension up. This is a person who has lived in the gray area between legitimate commerce and outright crime. No surprise that they are now employed in such dangerous and shady work.

Felix has spent 100 of his starting 110 coins to retain two hirelings for five days each. Should he survive one or more delves, he hopes to gather enough money to hit level 2 and retain some more sturdy companions to accompany him on future delves.

Clotilde Delamorn, hireling

  • AC 11
  • HP 3
  • Level 1
  • Attack punch d2
  • MOV 40’
  • MRL 4 
  • 10 item slots

Guinevere Westerfield, hireling

  • AC 11
  • HP 3
  • Level 1
  • Attack punch d2
  • MOV 40’
  • MRL 4 
  • 10 item slots

They carry some cheap sacks for loot, and nothing else. We’ll sketch out more about Clotilde and Guinevere (and Felix, for that matter) if they survive long enough to warrant our interest.
