The Rusted Colossus: 01 | Concept, Structure, and WIP Cover Art

Oh hi there, fancy seeing you here…

I’m deep in the guts of my latest project: The Rusted Colossus, a GOZR one-shot adventure. Planning to publish it—probably as a zine, definitely as a PDF.

I figured that some of you folks might be interested in self publishing your own content too, so I’m gonna do a little irregular series on the journey documenting all my missteps for educational and entertainment purposes.

Also, if you have experience of this, please get in touch if you have any advice!

Concept

I knew upfront that I wanted to do a one shot, and design it with GOZR in mind. I really like GOZR, but I do think it’s popularity suffers from a lack of published adventures which is something I can help with, and in terms of project size — doing a one shot seems much more achievable than trying to design an Event Based Campaign or a Sandbox (Besides, GOZR itself has a pretty good sandbox generation kit in it’s own rules that’s ready to go).

Armed with this knowledge, I brainstormed a few quick ideas brazenly inspired by a lifetime of consumed nerd culture and came up with 5 basic concepts:

1. The Shattered Gozspire – A broken tower of ancient Gozr technology pulses with unstable energy.

2. Flesh Carnival of the Ooze King – A living fairground of writhing meat and grotesque amusements.

3. The Wyrm That Burrows the Sky – A sky-eating mega-worm carves a tunnel through reality.

4. The Rusted Colossus – A giant, dead machine-being lies half-buried in the wastes.

5. The Halls of the Forgotten Gozr – A tomb-city of long-lost Gozr elders, now ghostly echoes.

Of these, the Rusted Colossus spoke to me the most, I love me a big robot, I do. I could picture this giant mech from the before times being uncovered by the shifting sands of the Ghost Dunes, with the pilot still alive but twisted inside. Why is the Mech there? Who is the pilot? What does he want? Juicy.

Structure

A dungeon is the perfect setting for a one-shot. But in TTRPG terms, a "dungeon" doesn’t have to be stone walls and torch-lit corridors—. It’s just a closed adventure space that says, “This is where the action happens”.

But what type of dungeon? Well, it’s a one shot, so I don’t want anything large, or complicated that would hinder the completion of the adventure in one session. That rules out a Megadungeon then!

I decided to do a bit of research and ended up reminding myself of the Five Room Dungeon by roleplayingtips as well discovering the Dungeon Checklist by Goblin Punch. Both of which have helped me to think about how the dungeon breaks down into creamy chunks. I’ll start covering the specific of those later, but for now, the overview:

Five Room Dungeon

The 5RD says that your one shot dungeon should contain five rooms (o, rly?!) and should follow the narrative story structure of the hero’s journey, with each room representing a step on that path:

1. A Guardian - The reason no one already cleared this dungeon out. Often a combat, but not neccesarily.

2. A Puzzle

3. A Setback - Usually a trick or a trap that forces a strategic adjustment

4. The climax - Typically your BBEG, but not necessarily a combat.

5. A Reward, or Plot Twist

You don’t have to approach these in this set order, and you don’t have to approach these as a linear path either. Nor do you have to treat these 5 rooms as literally 5 rooms, rather as five zones? Does that make sense?

Dungeon Checklist

Goblin Punch’s checklist here is pretty detailed, so I’d encourage you to check it out yourself for deep details. Here it is, cross examined against the 5RD framework:

1. Something to steal - This straddles the idea of “a reward” from the 5rd.

2. Something to be killed - The “guardian” from 5RD, and any other baddies would seem to fit this.

3. Something to kill you - A difficult combat encounter or trap, I think this is covered by the BBEG in “the climax” and potentially the “plot twist”.

4. Different paths - Interesting one for a 5RD, the idea is that the players experience the full five zones, so I’ll need to consider how to make the path the PCs take have actual consequences.

5. Someone to talk to - I think this could be covered twice, with the “guardian” and “the climax” with the BBEG, with both allowing combat to be avoided.

6. Something to experiment with - This would work with the “puzzle” room.

7. Something the players probably won’t find - This exists outside the 5RD structure I think, but I do quite like the idea of tucking a hidden secret in there that only the most cunning players will find for some extra reward.

The Front Cover

Wow, that was some hard thinking. Who’s up for some pretty pictures?

My vision for the front cover is to provide support to the adventure hook, so an illustration from the POV of the PCs with the Colossus looming over them from the distance, half covered by the Ghost Dunes. I love JV West’s evocative verse at the start of GOZR too, and I had to do something similar, handwritten and raw.

One problem though: I’m not a particularly gifted artist, but it’s not for a lack of enthusiasm or enjoyment :) My process here was to sketch out some stuff in pencil drawing from references, like carefully posed toy robots, and Battletech and Gundam art for details. Unfortunately my neuro-spicey super powers do not extend to being able to see and hold mentally generated images in my minds eye with sustainable clarity, which definitely puts a crimp on my artistic aspirations!

Anyway, where was I? Oh yeah, make sketches from references for the individual elements on different pieces of paper, pen over them with black POSCAs, then scan them into my PC. From there, pull them into a super old version of photoshop as individual layers, adjust the thresholds to restrict the image to pure black and white, delete the white and add the colour. Things like the hand-written text can be coloured, stroked, drop shadowed, resized, and repositioned too which is super helpful.

These are my penned over sketches:

And here’s a low res couple of photos of my monitor showing how the front cover is looking right now. I’m trying to decide if the Gooz in the foreground should have red or white highlights. I’m leaning towards red, what do you think?

The other thing I did was reach out to JV West and ask him about his 3rd party license for GOZR, which he’s kindly directed me towards. Following the terms of the license lets me put that cool little badge in the bottom corner of the work, and lends the work a degree of credibility.

Also, I think it’s polite right? To let the original creator know what you’re doing and get their blessing?

Conclusion

Phew, long one this. Sorry about that, I normally like to keep it concise. Anyway, I hope you enjoyed this, you’d be doing me a massive favour if you could share this post on your socials - see if we can build up a bit of hype, and keep me motivated to continue through engagement!

I’ll be posting another one of these as and when I’ve got something to report, so the posting schedule will exist outside the usual weekly cadence of posts.

Hey, thanks for reading - you’re good people. If you’ve enjoyed reading this and want to make sure that you don’t miss any future updates, maybe think about subscribing to the Mailer of Many Things! Either way, catch you later.
