A review of the original Tower of Zenopus adventure ↑

Pre-G1 Modules, part 5 - The Tower of Zenopus

So you probably noticed that this is being posted after G1. Sorry! File this in July 1977, so just after DK1 and 2 and Tsojconth and City-State and Tegel Manor but before Thieves of Badabaskor et c.

This post being released out of order is a function of where Zenopus is hiding. You see, the dating of Holmes Basic is a little squirrely. Most places say 1977 broadly, some people will say "the earliest reference is an ad in Dungeon in September '77", and a few internet sleuths say July 11th . So I hadn't had that down in my to-review list before I released G1, and in the rush I had forgotten that hiding in the back of Holmes Basic is the beloved little module simply entitled "Sample Dungeon", later known as The Tower of Zenopus.

And, consequently, I have no fancy cover to show you! Just this hand-drawn little map:

The Tower is unique in that it is the first module on this list that I have actually run for a real party. Now, granted, I did not run the Tower in Holmes Basic (I ran it in Fantasy AGE 2nd edition), but nonetheless -- it's the first one I have personal knowledge of. And I love it quite a bit.

So historywise Holmes Basic has a lot going on that I cannot quickly explain, so simply accept that Eric Holmes offered and was eventually hired to re-edit Original Dungeons and Dragons ("Little Brown Booklets") into a less labyrinthine mess. This was an extremely good call, and the Basic productline would go on to live for a very very long time in one form or another, only getting seriously changed much later by Frank Mentzer in 1983. There is a lot of Corporate Politics wrapped up in the release of ADND vs Basic vs Original DND, with concerns about copyrights and royalties and extremely Type A Gary Gygax not wanting to share his toys with the others. And, done.

The Tower is interesting from a historical standpoint in that whereas The Tower of the Frog is "here is a dungeon, here is what that looks like", Tower of Zenopus is "here is how to make a dungeon, and this is a dungeon that will teach players how to play". There will be far better attempts at those two goals, but nonetheless Tower represents a module that genuinely holds up in 2024 with some cleanup. It was given a loving nod in 5e's Ghosts of Saltmarsh by having the neighboring Portown be a little up the coast from Saltmarsh and I strongly recommend having that be your second adventure after the haunted house.

So, what's Tower's backstory? Both more and less than you'd expect. Zenopus built the tower next to the graveyard, it was suddenly engulfed in green flame, Zenopus was killed "by some powerful force he had unleashe din the depths of the tower", and it sat around for a bit. The villagers saw spooky shit going on there and smashed it with a catapult. Your party has assembled in the Green Dragon Inn and is going to investigate for phat lewt. Go on, scamp!

The structure of the tower is unusually genius for an early module, in that it features a lot of routing loops that allow for nonlinear but clear movement through the dungeon. The overall structure is, ultimately, a rimmed wheel, an outer ring connected by spokes to the hub. The shape hides this well but not too well, which is perfect for the new DM. So here's the room by room highlights:

The party enters on a four-way intersection, each taking you to a different feature of the dungeon. I have heard this dungeon describes as "like a theme park with four wings" and that's an apt descriptor here -- you're picking between the rat area, the pirates area, the wizard area, and the tomb area.

A very cute and simple puzzle, which is one of those most precious things in life: a four-way room freely opens from the outside, but only lets you out from one door. A statue in the center points towards the door that is currently open, and the statue can be spun to change the door. It's a neat little trick in that if the party gets separated during combat, anyone in this room can't assist anymore unless they work out the trap, but outside of combat it is largely a non-issue so long as they take the time to puzzle it out.

A pretty standard but new for the time tell that the wizard has a petrification wand with a little garden of stony adventurers. It's a classic for a reason.

A regulation water-rush trap that separates the party with the current -- again, a certified classic, creating tension by making fair encounters that are hard if the players get separated by traps

Ye olde "question answering mask" with, again, a precious simple puzzle: a tiny little riddle. If you parse out that the mask is powered by the sundial, you can abuse your light sources to make it be 4pm.

G i a n t c r a b, the most classic of scary "normal monsters", because it is armored and hits hard but people still immediately understand "oh fuck it's a crab" in the way they understand a bear is a serious issue

Giant spiders ambush from the ceiling silently. Zenopus really is a classics fest, but in 2024 that's kind of novel simply because THIS type of classic isn't done anymore.

For reasons I cannot fathom, the local pirates have taken to smuggling in the Tower because it's connected to the sea. This works in Ghosts because Portown is abandoned and so it's far away, but as-mentioned in the original module the tower has to be suuuuper far away from town, but also near enough to be the graveyard, for it to be a good smuggler's den. Regardless, there's a canned setpiece in the sea access room where pirates are coming on boats with a kidnapped noble lady from Portown. They're moving in on skiffs when, a giant octopus attacks! It's very, very good. This is, for my money, the best room in the dungeon and also one of the best moments in DND until we get all the way to N1's tavern.

In the center of the dungeon is a staircase leading up into the remains of the tower -- I made a rather major change from the original here, the original is merely an old alchemist's laboratory complete with a pet ape.

Instead of the alchemy lab, for my adventure I made a rather large change: the original module suggests expanding downwards because That Is How It Was Done in 1974. Instead, I went up. The horrible thing Zenopus discovered had formed a shadowy parallel dimension, so they were in a pocket dimension where the old tower was, even though in the prime material plane it was simply rubble. This blog is not About My Modifications but, that's my free tip about the tower if you ever run it -- subvert the old timey expectations by making it an upward dungeon instead of a downward dungeon, with the power of weird magic.

Anyway, that was all, and amends are now made for my previous error. See you in checks notes like 5 hours with G2!
