The Pitch

Let’s cut to the chase. This adventure is about a lighthouse (welcome back). It has fishpeople, except this time they’re electric eels. It has a summoning ritual, except this time they’re summoning water elementals. And it has boats. Why are we reviewing this? Because the product design is exceptionally good. So let’s talk about that…



Kelsey Dionne writes for game masters. She doesn’t write for readers who won’t play or other adventure writers. She writes her games to be played, and she does it well.

The Secrets of Skyhorn Lighthouse makes a dozen decisions that nod to this practice, but what I like is how they conclude with one viewpoint. Her products know what it means to have pacing. Not three-act structures. Or rising and falling actions. Or a hero’s journey. But practical, non-theoretical ways to control pacing.

There are no read aloud boxes. Instead each element is given one or two sentences. These same elements are then listed as bullet points. If something like a 10-foot stone wall is prevalent it gets bolded everytime it appears. These are the nods that make the adventure easy to run. But that’s not the innovation.

The innovation is how the adventure breaks down into scenes. Each page is one scene. The top of the page starts it. The middle develops it. And the bottom shows how to transition to the next one.

This product states that if a scene has been resolved, the dungeon master should transition to the next one. You know when it’s resolved because each scene has its conflict or “dramatic question” outlined. What’s unique is how the dungeon master is instructed to transition to the next scene as soon as the tension is over. For example, if combat is decided, Dionne says you should summarize it.

Yes. To all the gods of the Forgotten Realms, Greyhawk, and Birthright. Yes. That’s pacing. We all know combat can become rote. There’s always something else to roleplay. Finally, permission to move on in a DMs Guild adventure.


The Good

I cannot stress how important good adventure design is. It makes good things great. Boring things good. Bad things tolerable. Because this adventure is so user-friendly you can punch up the boring stuff, pivot away from bad stuff, and never miss the real jewels.

This adventure has a decent range of encounters from appeasing pirates to chopping up baddies while waist-deep in water. It’s a solid spine to riff on. Time you’d be wasting doing prep on other adventures.

The Bad

The writing isn’t especially evocative. It all reads too familiar. The docks are choked with boats. The lighthouse has a blazing beam of light that spins slowly. None of the descriptions are visceral. None of these feel like new sentences.

The Nice

This adventure has new monsters, character summaries, hyperlinks to SRD web pages within the text. There are even links to youtube videos with walkthroughs. If you’re the sort of person who has a Fantasy Grounds account, this adventure is compatible. And if you’re a luddite there’s a printer friendly version too. It’s a holistic production, something you’d notice if you played other adventures.


Buy or not buy?

Yes. It’s free. If you’re going to be running any campaign near a coast you can have this in your back pocket. It’s a good adventure. It’s not short but it’s not bloated either.

Here’s what you should do, get this adventure for free and give it a look. If you like what you see, go to and buy stuff from The Arcane Library. Sitting down with this adventure was a pleasure. It respected the craft. A couple times I smiled because it felt like a letter from another dungeon master. They deserve to be paid for it.
