The Old World is burning on every frontier, and Grand Cathay is no exception.
While western lands crumble under Undead hosts and Chaos invasions, the Celestial Dragon’s realm braces itself for disaster. With the release of Arcane Journal: The Breaching of the Great Bastion, players finally get a deep dive into what happens when Chaos comes knocking at Cathay’s own gates. As a long-time Warhammer player, this is exactly the kind of grounded lore expansion Cathay needed. Moreover, it firmly anchors the faction within the wider narrative of Warhammer: The Old World.
Why the Great Bastion Matters Now
Until recently, much of Grand Cathay’s story unfolded at a distance, often tied to expeditions westward. However, the designers realized that the arrival of new Cathayan miniatures demanded a closer look at home defenses. As a result, this Arcane Journal pivots the camera inward. It asks the obvious question players have been raising for months: what happens when Chaos does not stop at the wall?
The answer is grim but fascinating. While Cathay aids its allies abroad, its own borders strain under constant pressure. Therefore, the Great Bastion becomes more than scenery. It becomes the defining symbol of survival against the Ruinous Powers.
New Units, Deeper Lore, and Real Context
This supplement builds directly on the newest Cathay releases, including Peasant Levy, Crane Gunner Teams, Iron Hail Gunners, and Astromancers of the Celestial Court. These are not just tabletop additions. Instead, they are everyday defenders of the realm. Consequently, the book uses them as a springboard to explore Cathay’s military structure and social fabric.
There is also a detailed historical timeline tracing Grand Cathay from the era of the Old Ones to the present age. That context matters because it frames Cathay as ancient, deliberate, and deeply scarred by past wars. In addition, the journal explores the Northern, Western, and Imperial Provinces, mapping cities, landmarks, and regional threats in practical detail.
Dragons, Magic, and the Machinery of Power
One of the strongest sections dives into Celestial magic and how Cathayan Dragons manipulate the Elemental Winds. Unlike the western understanding of magic, Cathay treats it as a managed resource. The Astromantic Court oversees this balance, while the mysterious Wu Xing Compass within the Celestial Palace helps regulate magical flow itself.
This is classic Warhammer worldbuilding. It is arcane, political, and quietly terrifying. Moreover, it reinforces why Cathay has survived for so long while others have fallen.
Enemies on Every Border
Threats come from all directions. Sea raiders harass the fleets of Yin Yin. Western mountain tribes cross the Warpstone Desert to challenge Zhao Ming. To the south, the Monkey King’s forces clash endlessly with Li Dao. Meanwhile, the Northern Provinces endure relentless assaults from Kurgan Marauders and Chaos Warriors.
Importantly, the narrative section shows how these invasions unfold just before the events of Dawn of the Storm Dragon. Even when Chaos breaches the Bastion, it never marches unopposed. Cathay bleeds, but it does not break.
Summary
Arcane Journal: The Breaching of the Great Bastion finally gives Grand Cathay the internal focus it deserves. It expands the faction’s history, clarifies its magic, and grounds its new units in lived conflict. If you care about Cathay as more than an export army, this book is essential. Pre-orders open Saturday, and for lore fans, this feels like a cornerstone release.
