Welcome to the Ravenglass Universe

Epic fantasy where hope bleeds, but never dies.

Wyverns bonded by blood. A black material that warps light and refuses to break. Empires that rise, conquer, peak, and crumble across a thousand years of history.

I’m Jon Cronshaw—author of the Ravenglass Universe and self-appointed King of Nobledark. I write epic fantasy for readers who want their heroes flawed, their magic costly, and their empires morally complicated.

No spice. Deep characters. Complex stories that earn their weight. If you’re here for the world and the people inside it, you’re in the right place.

Ravenglass Legends — Books 1–3 Boxed Set

 “Epic fantasy at its best.”

Rating: 5 out of 5.

The Empire took his home. Then it made him a knight.

Black ships on the horizon. A father’s head on the block. A sister dragged away in chains. By the time the smoke cleared over Meerand, fifteen-year-old Ragnar Wolfsbane had lost everything but his name—and the Empire was already deciding what to do with that.

Years later, they call him Sir Ragnar. Knight Protector of the Ostreich Empire. The very thing he was raised to kill.

But Maja is alive. The wyverns are circling. And ravenglass remembers.

Three full novels. One conquered kingdom. A brother and sister forced to choose between vengeance and survival in an empire built on lies.

For readers of Bernard Cornwell, John Gwynne, and Anthony Ryan.

Available on Kindle and Kindle Unlimited.

STEP INSIDE THE RAVENGLASS UNIVERSE

A thousand years. Four eras. One unfolding history.

The Ravenglass Universe spans royal sisters and bonded wyverns in the First Kingdom, brutal conquest and rebellion in the Expansion, prophecy and divine power at the High Empire’s peak, and shadow warfare through the slow Retraction that ends it all.

Every series stands alone. Read in any order. Or follow them across centuries and watch a civilisation rise and fall — with a black wyvern named Witz drifting through the wreckage, present at every turning point, claimed by no one.

LISTEN TO THE LATEST AUTHOR DIARYThe campfire between books.

Every week, I sit down and talk about what I’m writing, what I’m reading, what’s gone wrong this week, and what I’m doing about it. New books taking shape. Old ones getting their second pass. The occasional detour into wrestling, running, or whatever I’m currently obsessed with.

It’s the Author Diary—part writing journal, part workshop notes, part me thinking out loud about the Ravenglass Universe and what’s coming next. No script. No production team. Just a writer with a microphone, talking to whoever’s listening.

If you’ve ever wanted to know what the inside of a working novelist’s week actually looks like—start here. New episode every week.

If the Author Diary is the campfire out front, Patreon is the room just inside the door—where the Universe’s deeper workings live, and the readers who want more than the books gather between releases.

I post on Patreon every week. New chapters. Exclusive stories. Lore documents.  

Free members get the door open. Public posts. Weekly updates. A front-row seat to what’s coming before it lands on Amazon. You don’t need to pay a penny to be part of the community.

Paid members get the inside track:

  • Exclusive novellas and stories — Wyvern Rider, The Long Night, The Skald’s Quest, The Princess and the Tailor, Orphan Farm Boy of Destiny, and others you won’t find anywhere else
  • Early access to new books — read chapters in progress, months before publication
  • 🗝 Behind the curtain — drafts, lore documents, magic-system workings
  • A say in what comes next — help shape what I write after the current series wraps
  • A direct line — questions answered from the writer’s chair, not the storefront
