The Ravenglass Universe is an epic, interconnected fantasy world created by British author Jon Cronshaw.
Rich in history, political intrigue, personal drama, and wyvern magic, the universe spans over a thousand years of in-world history and multiple series.
While each series can be read on its own, they all connect through recurring characters, families, relics, and one mysterious wyvern: Witz.
Whether you’re drawn to royal succession drama, grimdark warfare, coming-of-age fantasy, or brutal assassin tales, there’s no wrong place to begin—just start with book one of whichever series catches your eye.
Here’s a breakdown of the four major eras and how the stories fit together.
First Kingdom Era (Years 0–200)
Themes: Dynastic power struggles, royal succession, the early role of wyverns in politics
📘 The Ravenglass Throne

A sweeping royal fantasy told in serial format, The Ravenglass Throne follows three sisters—Irmin, Adelinde, and Elana—each trained in a different discipline: war, knowledge, and diplomacy. After the king’s sudden assassination without naming an heir, the sisters must navigate court politics, hidden conspiracies, and the secrets surrounding the powerful material known as ravenglass.

This 22-part fantasy saga is structured around the Major Arcana of the Tarot, with each instalment reflecting a new stage in Kat’s journey—from The Magician through The Tower and finally The World.

The Witz Meta-Story
A hidden thread binding the Ravenglass Universe
Across centuries, a single character weaves in and out of history: Witz, the black wyvern. At times advisor, at others manipulator or even deceiver. His motivations remain unclear—but his influence is undeniable.
All series titled Ravenglass (Throne, Legends, Chronicles) feature Witz in key roles. His story emerges slowly, and readers can piece together his true nature by reading across the full universe.
