Title: The Game Master’s Guide to the Leo Galaxy: Rules, Lore, and the Living Universe Date: January 2026 By: Captain Hedges
I Am Handing You the Keys to the Universe
We’ve talked about the ships. We’ve talked about the monsters. But today, I’m pulling back the curtain on the biggest secret of 2026.
I’m giving you the Game Master’s Guide to the Leo Galaxy Sector.
This isn’t just another sci-fi setting where you fly from Dead Rock A to Dead Rock B. This is something different. I built this campaign to be the ultimate sandbox for GMs who are tired of doing math and ready to start telling stories.
The Ingredients of a Galaxy
To build the Leo Galaxy, standard sci-fi rules weren't enough. I wanted the grit of a dungeon crawler, the whimsy of pulp 70s sci-fi, and the speed of modern gaming. So, I am cracking open the archives. This campaign is a "Frankenstein Fusion" of the best systems ever made:
Monsters! Monsters! (Zero, 2.7 & MoZ): This is the heart of it. We use the raw, brutal combat stats from the core rules and the deep lore from the Monsterary of Zimrala (MoZ). Whether it's a Tygerian Marine ripping open an airlock or a wizard casting a spell, it all runs on Ken St. Andre's engine.
Starfaring: Ken’s original 1976 sci-fi masterpiece. This provides the "pulp soul" of our universe.
Open D6: The glue that holds it all together. It gives us a robust framework for starship combat, capital ship movements, and massive battles.
We are taking the Zimrala One and running it with rules meant for slaying dragons and rules meant for blowing up Death Stars.
The Universe Breathes
Now that you know the rules, here is the core truth of the setting: The Leo Galaxy isn’t just a place. It’s a person.
In this lore, the universe is a sentient entity known as Leo, the Celestial Lion. He is the Lion of Judah, the sovereign of creation. When you look at the star map, you aren’t looking at random clusters of gas; you are looking at the biology of a god. The galaxies are his muscles. The stars are his nerve endings. The nebulas are his spirit.
And like any living thing, Leo breathes.
This is the mechanic that changes everything. The "Apocalypses" that happen in this sector aren't random disasters. They are the Cycle of the Breath. When Leo exhales, entire civilizations might wither or implode. It sounds terrifying, but it’s necessary. It’s a cosmic purging to make way for new life.
As the Game Master (or "Resonator," as we call them here), your job isn’t just to referee a fight. Your job is to control the breath. You get to decide when the universe exhales.
The Heart of the Lion: Aetheria Prime
If Leo is the body, then Aetheria Prime is the heart. This is where the magic happens.
At the center of this system, we have the Primordial Twins—two super-dense, collapsed cosmic cores dancing around each other. They pump out the Aetheric Resonance (the "Sap of Creation") that powers everything from our starships to the Tygerian forges.
Orbiting these twins is Urland, the Ur-Seed. This isn’t a normal planet. It’s a bio-luminescent super-organism. The ground pulses with a heartbeat. The forests are nervous systems. The oceans are lymphatic fluid. If your players land here, they aren't walking on dirt—they are walking on a living thing.
The Star Chart: Where We Play
I wanted a galaxy that could handle any genre you wanted to run. Do you want military sci-fi? Fantasy? Horror? It’s all here in the key systems:
The Forge: Go to Tygeria (Zeta Leonis). This is the homeworld of the Tygerians, a place of floating mountain fortresses and magma forges. It’s brutal, industrial, and honorable.
The Jungle: Try Joralla. It’s a crimson world bathed in red light, full of predatory beauty and the avian Tikiarri warriors. It’s Predator meets Avatar.
The Graveyard: The Leo Ring. This is a gas cloud full of "failed worlds" and gravitational ghosts. It’s perfect for horror sessions.
The Refuge: Zimrala. This is our connection to the old world. It’s where the Ether Dragons evacuated the Trolls. It’s a sanctuary, but it’s also a powder keg of refugees and native species trying to coexist.
The Shadow Saga: The Void Sentinels
This part is personal to me.
In this setting, the Void Sentinels aren't your typical shiny space heroes. They are the legacy of the Tiger Force Shadow Saga. These are the veterans of Vietnam, Desert Shield, and Desert Storm—and their children. They have seen the horrors of war on Earth, and now they are fighting for the multiverse.
They believe that the only way to save reality is to trigger the "Celestial Roar"—a final apocalypse to reset the timeline. They are tragic, gritty, and dangerous. They add a layer of real-world weight to the high-fantasy concepts.
The Enigma: The USS Urland Universe
Finally, I have to mention the ghost story of the sector: The USS Urland Universe (NCC 27011-J).
Officially, this ship was a failure. In reality, it’s the most powerful vessel in existence. Thanks to O'Mally's Universal Core, the ship can rewrite physical laws around it. And with the J-Class Temporal Drive, it can jump through timelines.
It is the only ship capable of navigating the events of the Shadow Saga across different eras. It is the prize everyone is hunting for.
Get Ready to Roar
We have the ship. We have the map. We have the rules.
The Leo Galaxy is about Scale. One minute you are a detective in the neon streets of Nocturnis, and the next you are commanding a fleet against a cosmic horror that is exhaling a star-killing cloud.
The breath is coming. Are you ready to play?
