Hidden Tomb of Slaggoth the Necromancer Cover ArtSo, I wrote a small dungeon adventure module.

It started early this year when I stumbled on to the website of fellow D&D blogger, Stonewerks. Stonewerks primarily makes maps, and his work has heavily influenced the way I’ve drawn the Deadly Dungeons maps over the last few months. At the time, his newest post was “The Hidden Tomb of Slaggoth the Necromancer,” a map which caught my eye, both for its lovely design, and compelling description:

“The long lost Tomb of the evil necromancer Slaggoth, is buried deep with in a cavern complex. The caves have become the home of a trio of ogres and their band of goblin henchmen. The goblins guard the entrance by watching through a small crack in the rock above the entrance, alerting the other goblins when anyone approaches the entrance. The goblins will then unleash a small pack of wolves that they have chained in the front caves against the intruders. If the wolves are not enough to repel the intruders, the goblins will send a runner across the wooden rope bridge to the ogre lair to warn their masters and will use ambush and retreat tactics to slow down the intruders. In the ogre cave is a massive steel door that leads to the hidden tome of the evil Necromancer Slaggoth. They have never been able to breach the door, so the tomb has remained untouched. Rumors of a key to the steel door is hidden somewhere in the caves, but has yet to be found. What horrers lie within Slaggoth’s tomb? Who is brave enough or foolhardy enough to find out?” -Stonewerks

Stonewerks and I got to talking in the comments, and then via email. What started as me filling a lazy evening by keying an empty dungeon turned into a full-fledged attempt to write my first module based on Stonewerks’ seed idea. I dragged several people through playtests and proof readings, and even got cbMorrie and Jacob Rain (both of whom have been featured on P&P before) to provide some free art for it.

The module proper has actually been done for several months now. The work of getting everything written, tested, re-written, and edited only took a few weeks. The art took a few weeks more than that. The hard part, as it turns out, was making a PDF. It’s not something I’d done before, and I found it a frustrating process to start with. One which I procrastinated over and over again. I’ve got a pretty fair handle on how to do it now, though, so hopefully future attempts won’t take quite so ridiculously long!

So please, download it! Let me know what you like or what you hate. Run it for your group if you are so inclined, and if you do, let me know how it goes! This is an experiment for me. One which will hopefully pave the way to future products.


I think it succeeds much more than most adventure supplements, and I’d be happy if this adventure represented the quality baseline of OSR fantasy.” -Bryce Lynch

 “a very fun adventure that could be great for one shots or a couple of evenings of play to introduce new players to old school games.” -Teh Badger

Clever and weird adventures with a clearly pulp asthetic that can be used straight across ANY edition are rare, but being free and of such quality is a very rare combination indeed. Grab and download this one folks. You won’t be sorry.” -Needles

a real nice 1st effort that is far better than my first couple years of adventure writing for sure.” -The Frugal GM

This led the party to the crypt room with Slaggoth’s corpse. Her sarcophagus rested on a raised dais at the back of the crypt. Six pillars running through the room had statues of skeletons carved into them. Slaughto had the bright idea to tie ropes around each of the statues legs just in case the statutes became animated. (Spoiler alert: Very good decision!)

Kharl tried sliding the lid off the sarcophagus. This caused the six stone skeleton golems to animate, just as Slaughto fears. The golems all toppled over due to the ropes.” – A full play report from Buttmonkey on the Troll Lord Games forums.

“I’ve run Slaggoth’s a few times for people as an intro to OSR. I put it up there (with minor alterations) with Finch’s Tomb of the Iron God and Raggi’s Tower of the Star Gazer as awesome starting adventures.” -LBriar of Reddit, sent to me in a private message.

  1. I am so proud of what you created here with this, I look foward to seeing more greatness from you. Awesome Job Nick!!!

    1. Thanks, Adrian! It was a lot of fun working with your map. It got me motivated to do something I’m really proud of.

  2. On Page 5 of the PDF the last sentence of section 6 “Mourning Chamber” abruptly ends without listing the gold value of the brass lighter. You do provide the value in the table directly below the sentence, but I thought this might be something you’d want to change.

    I love the module! It’s concise and leaves wiggle room for DMs to make it their own. I want to see more. Is there a followup in the works?

    1. Robert,

      Thank you very kindly for pointing out that error! I apologize for taking so long to get back to you. I’ve fixed it now.

      I have some ideas for a follow up module. I’ve actually got dozens of ideas. Unfortunately none of them are in the works right now, because I’m working on a different pdf. But a follow-up to hidden tomb of slaggoth might come after that. And let me tell you: slaggoth’s tower is CRAZY!

      Thanks for enjoying my module.

  3. Hey Nick! Great adventure. Thanks for writing up. I especially love the little details that add so much color to the scenario. Everything from tactical advice, cause and effect suggestions, axe-blades broken off in spider skulls . . . all stokes my imagination. Cheers!

    When is the next one coming out? :)

    1. Thanks for saying so, Jon! I wanted to write a module with the GM tools that I always wish I had, and with a lot of help from my contributors, I think we did a pretty decent job of it. The axe blade in the spider’s head was a particular favorite of mine!

      There’s a bit of a wait for the next one, I’m afraid. After completing this project I decided to tackle something a little larger. Right now, I’m working on putting together a full sized monster book with ~300 entries. It’s a project which has filled up a lot of game design time.

      However, I do have a lot of ideas for “STN2: The Sideways Tower” (or something to that effect). It’s a project I hope to work on once the monster book is done.

      1. Your adventure inspired me to create a map for Slagoth’s sideways tower/fortress. I may just do it up as an entry for the One Page Dungeon Contest (2014), but it was your stuff that got me rolling. You and A.J. at Stoneworks.

        If I enter it in the OPD2014, I will not use “Slagoth” or any reference to that character. I’ll likely run my players through both of your adventures in the series, and Slagoth will feature large. :)
