When Sean McCoy proposed the Dungeon23 project, I couldn't help but join in. I wrote two dungeons--one for His Majesty the Worm and one for Under Hill, By Water. This effort eventually went on to become the 100+ room, Metroidvania-inspired dungeon...
The Castle Automatic
The premise of The Castle Automatic is that there is a mechanical castle with a self-contained sun, moon, and seasons. It was once ruled by a cruel giant emperor, but has since fallen into ruin and become haunted by vampires and wind-up golems who play-act a continual faction war. Players need to repair the engines of the castle in order to control the flow of time inside it and change the environment to solve puzzles and find treasure.
But I had been noodling on the basic idea for this dungeon for many years. It had taken root there when I was just a small child.
The True Origins of The Castle Automatic
There is an unfinished blogpost sitting in my drafts that I started I don't know how many years ago. I found it recently. Here is a screenshot of it, in its entirety.

To summarize the aborted post, there is a children's show that I lives half-formed in my memories called Eureka's Castle (1989-1991). It consisted of a bunch of muppets--a wizard, a dragon, a bat, etc.--who lived in a wind-up castle owned by a giant. Here's a link to the intro. Perhaps you remember it?
The show certainly wasn't a favorite of mine. I never had cable TV. I mostly watched it on doctor's office TVs or when I visited my aunt. But something about it stuck in my brain. When I was doing the work of writing one room a day, those memories came came spilling into my new dungeon.
To give you a preview of The Castle Automatic, I'll post some screenshots from the book of NPCs and dungeon features, then show you the puppets that inspired them.

Mr. Knack

| A weird little fellow. My players hated him in playtesting (positive). |
Something I think is cool is this haggling mechanic I snuck in for Mr. Knack: "The price listed is his starting cost. He will come down as much as 50% off of this cost. He will only entertain as many counter-offers as the haggler’s Wands score before he puts his foot down and insists on a final price." Often, rules for Worm are just rulings that I made during my sessions that seem to work.

Pimple the Vampiric Torturer
R.L. Stein was a writer on Eureka's Castle. You can see the resemblance between him and the bat, Batley.
The equivalent in the Castle Automatic is Pimple, one of the vampires that now haunt the ruin. He is the torturer and delights in making captured PCs spin his giant Wheel of Fortune, which gives them bizarre banes.

| Batley was terribly nearsighted. Pimple is, too, and takes disfavor on attacks because of it. |
Something I think is cool is the Challenge page on the right. I have a ton of these throughout the module, all illustrated by Tiger Wizard. They are intended to be handouts for set piece battles that can occur through the dungeon. These pages delineate the different zones of a Challenge if a fight breaks out in a particular room and outlines special rules that make that fight fun and different. You can see Pimple looming up abstractly in the corner.
