Welcome, Companions

Gratitude to Cobra Commander (Mike) for submitting a game proposal for this PUM Event round!

The PUM Solo RPG Event is an opportunity for all players of PUM Companion in the community to play a common game and share stories starting from the same plot seed. This is a great opportunity to play, share, and learn!

The premise is SUPER SIMPLE: Download the .PUMC file below and load it in the app, read through its contents and start playing. When ready, open a thread in our Discord community event channel and submit your play, either as you go, or as you finish it through! Read other players’ submissions and share your thoughts.

The game brings its own system and homebrew, but players are free to modify it or play their own favorite TTRPG with it. Mike put incredible amount of quality effort into pulling this plot seed together! Can’t wait to play myself!

The Game: Immortal Chicago

You are an Immortal living in modern-day Chicago, hiding among millions while playing The Game in secret.

Immortals cannot die except by beheading, and when one falls, their power, the Quickening, passes to the victor in a violent surge of memory and force. Chicago has recently become unstable. Too many Immortals are moving openly, Watchers are nervous, and someone is breaking long-standing rules. Bodies are appearing without heads. Sanctuaries are being violated.

You must survive, uncover what is changing, and decide what kind of Immortal you will be in a city that is starting to remember what it has forgotten.

What’s included

Introduction to the game story
Gamemaster Plot Scope + Instructions for the Solo RPG Player

3 deep Compendium entries with World Building and Homebrew Mechanics
20+ Random Tables integrated for PUM Companion play

Template Character Sheets and Locations ready to use

Game tone

Urban fantasy, grounded
Personal history colliding with modern systems
Violence is rare, fast, and consequential
Secrecy matters as much as strength

A note from the author

Hey everyone,

First, thank you for your interest in Immortal Chicago. This is my first attempt at designing a
solo game, and I’m incredibly excited to see the stories you create with it. I recently discovered
PUM Companion and immediately wanted to try building something inside this amazing tool.
This game is the result of that spark.

As a teenager, I fell in love with the world of Highlander. Watching the first film was a formative
experience for me, I’m pretty sure I wore out the tape from repeat viewings. The idea of
immortals walking among us, locked in a hidden struggle where there can be only one,
completely captured my imagination. It felt like modern mythology, just believable enough to
possibly be real.

I discovered tabletop roleplaying during a turbulent chapter of my life. I had just packed
everything I owned into my car and moved to Chicago to begin working in the film industry.
TTRPGs, especially Dungeons & Dragons, became a lifeline, helping me stay connected with
friends back home while I built a new life in a new city. That move turned into a 20-year career in
film, full of highs and lows, with tabletop games as the one constant throughout.
Immortal Chicago is where all of those paths meet. When I opened PUM Companion, the idea
hit instantly: what if I combined everything I’ve learned about the incredible city I called home for
so long with the mythic tension of Highlander? It felt inevitable. So I got to work.
Now the story belongs to you.

Will you play a newly awakened immortal? A Watcher who can’t resist getting involved? A weary
veteran of the Game who once marched in Agamemnon’s army? The city is waiting, and your
legend is just beginning.

But remember… in the end, there can be only one.
— Mike “The Serious Wizard” Pisani

On the Author’s AI utilization

I essentially used gen ai for the image generation so that the project would have art. If it were something I was going to sell I’d have used stock art or commissioned some art, but I thought this would be nicer than just having an empty project. I think it also ended up capturing the mood quite well.
If a product is something I’ll be selling I’ll always advocate for real artists, but for something like this I think it allowed me to improve the experience without a huge cost to myself.
