This Is Not the Beginning of a Story. It Is the Beginning of a Universe
The Sentinel Universe spans fifty million years of history. You are standing at the edge of it.
By Brian Bullock | Everyone Knows | X @EveryoneKnws1
Most science fiction tells you a story. A beginning, a middle, an end. Characters you love, a conflict that resolves, a final page where you close the book and let it sit on the shelf.
The Sentinel Universe does not work that way.
What you are reading right now — the short stories on this site, the trilogy coming to print, the audio library building week by week — is not the whole story. It is not even close to the whole story. It is the first light of a civilization-scale narrative that stretches from the birth of the first intelligent species in this galaxy to the moment humanity finally understands what it has inherited.
Fifty million years. Five complete series. Seventy-two short stories. One universe that was built from the ground up to reward every reader who goes deeper.
This is what it looks like from the outside.

Where You Are Right Now
You found the Sentinel Universe at its entry point. The Sentinel Trilogy — three books, three stages of one man’s transformation from a data analyst in Montana to the first human being to carry the weight of eleven thousand years of alien history — is the front door. It is the story designed to be read first, because it begins where you are: on Earth, in the present, with a man who knows nothing about what is buried under the Moon.
Bron Matthews does not start as a hero. He starts as someone running from his own life, walking into a Montana forest on a cold night with nowhere particular to be. What happens to him in that forest changes everything — not just for him, but for two species who have been waiting eleven thousand years for exactly that moment.
The Sentinel Trilogy is three books. Book One, The Sentinel of Crater Daedalus, is the discovery. Book Two, The Signal Answered, is the consequence. Book Three, The Return, is the reckoning. Together they tell a complete story. But they also open a door that leads somewhere much larger.

What Comes Next: The Awakening Trilogy
The Sentinel Trilogy ends. The universe does not.
Set ten years after the events of the trilogy, the Awakening Trilogy picks up a world that has been permanently changed. Humanity knows it is not alone. The Drossik are no longer a secret. The Ketheri, awakened from their eleven-thousand-year sleep, are relearning a civilization that left without them. And the alliance forged in the fire of the Vorai war is being tested by something more complicated than an enemy: peace.
New characters carry the Awakening Trilogy forward. New threats emerge — not from outside humanity, but from within the choices the Sentinel generation made and the consequences those choices set in motion. And at the center of it is a character who could only have been born from everything that came before: an AI built from two architectures, carrying inherited memories she was never meant to have, trying to understand what she is in a universe that has no category for her.
The Awakening Trilogy is already in development. It begins where the Sentinel generation ends — and it asks harder questions.

The Deep History: Three More Series
Behind the Sentinel Universe is fifty million years of history that the trilogy only hints at. The short stories are the first glimpse. The prequel series are where that history becomes fully visible.
The Dawn of Ketheri takes readers back twelve thousand years to the height of Ketheri civilization — before the plague, before the stasis, before the long sleep. It is the story of a species at the peak of what it could become, and of the choices that brought that peak to an end. Readers of the Sentinel Trilogy will recognize the names, the stations, the technology. The Dawn of Ketheri shows you how all of it was built.
Beyond that, two more series push the timeline back further than most science fiction has ever attempted. The Vorai Chronicles reaches fifty million years into the past, to the moment when the most dangerous force in this galaxy was not a monster but a mistake — a civilization so advanced it believed it could improve on what evolution had built, and was wrong in ways that echoed across geological time.
Between them sits Starforge — the age when the First, the oldest intelligence in this galaxy, were still present and active, still shaping the species that would eventually inherit what they built. The short stories already reference the First. Starforge is where you meet them.
Five series. One timeline. Every story in the Sentinel Universe connects to every other story, across fifty million years of cause and effect.

The Short Stories Are Not Side Content
The seventy-two short stories planned for the Sentinel Universe are not bonus material. They are not filler between books. They are the connective tissue of a civilization-scale story — the moments that happen offscreen in the novels, told from the perspectives of the people the trilogy never had room to follow.
The mother who ran through a burning city carrying her daughter and ended up guarding forty-three thousand children for the rest of her life. The pilot who stayed behind when everyone else went to sleep, keeping the lights on for forty-one years because someone had to. The commander who wrote an honest letter to his crew before climbing into a stasis pod, not knowing if he would ever wake up.
These stories exist in the same universe as Bron Matthews. Some of them happened thousands of years before he was born. Some of them set the conditions for the exact moment he touched that ship in the Montana forest. Read them and the trilogy becomes richer. Read the trilogy and the short stories become inevitable.
That is not an accident. It was designed.

Why It Was Built This Way
The Sentinel Universe was not written as a trilogy with optional extras. It was architected from the beginning as a complete fictional civilization — one with a real history, real consequences that ripple across time, real species whose choices thousands of years ago still echo in the present of the story.
The goal was simple and impossible: build a science fiction universe where every story rewards the reader who has read everything else, but every story also works completely on its own. Where the short stories are worth reading even if you never pick up the novels. Where the prequels are worth reading even if you start at the far end of the timeline. Where the universe has enough room to contain fifty million years of history without losing the human scale that makes any of it matter.
Whether that goal was achieved is for readers to decide. But the architecture is real, the timeline is mapped, and the stories are being written.
The Sentinel Trilogy is where it starts for most people. It does not have to be where it ends.

Where to Begin
If you are new to the Sentinel Universe, start with the short stories on this site. They are free, they are short, and they will tell you immediately whether this is a universe worth investing in. The Truck is the first one. It begins in Montana, in the snow, with an abandoned pickup and a clearing in the woods that does not make sense. Everything else follows from that.
If you have already read the short stories and you want more, the trilogy begins with The Sentinel of Crater Daedalus. Publication details are coming. The short story library will continue expanding in the meantime.
If you are already here for all of it — if fifty million years of history in a science fiction universe sounds exactly like what you have been looking for — then welcome. You found it early. That matters, because the people who find something early are the ones who get to watch it become what it was always going to be.
The Sentinel Universe is not finished. It has barely started.
That is the point.
