Beyond the Black Library: Sarah Cawkwell's Thunder's Edge- Echoes of Memory

by Jay "Lorehunter" Kirkman | Nov 28 2025

Anyone who's read the Black Library for any length of time will naturally have found a few writers whose work resonates with them. Have you ever wondered what they're up to outside of the Warhammer universe? I certainly have, and in Beyond the Black Library we turn a grimy, grimdark eye towards the fruits of the imagination that our authors have been hunched over their desks creating when they're not weaving tales of the Imperium or the Mortal Realms.

In our last feature we looked at Poison River, a Legends of the Five Rings mystery story from Black Library stalwart Josh Reynolds (Lukas the Trickster, Shadespire: The Mirrored City). Today we'll be switching gears into science-fiction and Sarah Cawkwell's new Twilight Imperium novel, Thunder's Edge: Echoes of Memory.

Access Denied

I've written before about the topic of accessibility in IP writing, and it's probably fair to say that the smaller the IP, the more prominent a role accessibility plays. For the Black Library, not only is the lore massive and sprawling, but the consumer market is substantial. As a result, writers to the franchise can usually expect a certain baseline of cultural literacy from its readers.

For instance, how many words are needed in each novel to explain what Space Marines are, or the Emperor of Mankind? Sure some books may perhaps be best appreciated by setting veterans, such as with Chris Thursten's Abraxia, Spear of the Everchosen (reviewed here), but in general Warhammer has multiple points of accessibility (tabletop, fiction, comics, video games, role-playing games, television series and appearances, etc.).

Now consider that calculus for Twilight Imperium. Currently in its fourth edition, the game debuted in 1997 and is published by Fantasy Flight1. Notorious both for its complexity as well as its lengthy gameplay (six-hour games are de rigueur), this is a property with a much smaller footprint. Aconyte Books has to-date published nine novels in the setting, starting with 2020's The Fractured Void by Tim Pratt2.

When they forecast their anticipated book sales, how much of that do they assume is from currently-franchised consumers and how much of that is penetration into new readership?

I felt that question acutely as I dove in to Sarah Cawkwell's Thunder's Edge: Echoes of Memory. This isn't just another Twilight Imperium book, but rather one that's tied directly to the Thunder's Edge expansion which released only last month. I came into the property cold, never having played a game of it and largely unfamiliar with anything about the game aside from its highly esteemed reputation with the tabletop community (it's an unsurprising 8.6 on Boardgamegeek). Would the book have plenty of onramps, or would it be geared at a more experienced audience?

Turns out, it was the latter. Thunder's Edge: Echoes of Memory presumes a certain amount of lore foreknowledge, with even the universe's different races getting little in the way of backgrounding. If you're going in cold, as I was, you may need to hit up Google a time or three to fully get your bearings and round out your understanding3. But the good news is, it's not that deep- Twilight Imperium's lore is fairly accessible on the whole.

The game's universe takes the core fantasy trope of making its races humanoid Earth-inhabitants, such as the mercantile lion-people (Hacan), fungus people (Arborec), lizard people (Ral Nel Consortium), robot people (Titans of Ul)- and of course baseline humans (Federation of Sol). In this I was actually reminded of an older board game I used to play as a kid, 1983's Shadowlord, which was a space-opera game with along with the humans had all sorts of alien races based on pigs, mice, and weasels- so there's certainly no shortage of precedent.

But it doesn't need to be deep- it just needs to be deep enough. And none of this is on Cawkwell, who can only work with what she's been given. So how does she do with it?

The Story

It's funny, but while I never could get into J. R. R. Tolkien as a kid (too dense, too dry4), so many of the books and saga I greedily devoured followed that same formula: a mismatched (often ragtag) group of heroes of diverse backgrounds coming together to undertake a perilous quest with enormous stakes. I mean, c'mon, tell me that's not half of TSR's catalogue- including the legendary (and much-beloved) Dragonlance, or (the other property that come to mind while reading this), 1980's Battle Beyond the Stars.

Cawkwell runs this same playbook in her story of a former Hacan general, Harrugh Gefhara, who must compile a mismatched group of heroes after getting a vision of the end of the world, finding himself in possession of two mysterious artifacts that could unlock the fate of the universe. Along the way he is helped by quirky, unique heroes from all different other factions, but the ultimate decision that must be made is his alone.

Sarah Cawkwell is a veteran of the Black Library with her first novel, The Gildar Rift, published in 2011 and her final contribution, the short story Awakened, released in 2020. She is perhaps best known for her well-regarded stories about the Silver Skulls successor chapter (and I was delighted to see a Silver Skulls cameo in Jonathan Beer's recent novel Tomb World, reviewed here), though I also particularly enjoyed 2012's Warhammer Fantasy character story, Valkia the Bloody.

Ultimately, I found this effort to be a book of two halves.

The first half focuses on the efforts of Gefhara to unlock the mystery of the vision and artifacts placed in his care, acquiring sidekicks like level-ups along the way. Because of the lack of lore onboarding, as an outsider the story struggled to gain emotional traction. Cawkwell writes well enough that I wasn't tempted to put the book down and start another, but at times I had to compel myself to soldier on.

Similarly, there was a bit of a thematic mismatch for a reader steeped in the Black Library. I think sometimes I forget how steeped in Warhammer I've become, to where reading something that's somewhat adjacent (sci-fi gaming fiction) but notably isn't grimdark is a bit jarring. There's a certain youthful, almost adolescent lightness of spirit that infuses the book, a feeling that was at once both distinct from what the bulk of my modern reading looks like yet echoed the feeling of reading books like the Dragonlance Saga when I was younger.

Characters tease and are silly with each other, and the crushing weights of truly high-stakes emotional adulthood and survival find only surface-level purchase in their depictions. In Gefhara, once the 'Golden General' and leader of the entire Hacan people, you won't find dark musings on how leadership in war means making hard decisions and sending good soldiers to their deaths, nor the kind of soul-deep wear you might expect from someone who's had to routinely make those sorts of decisions. Rather, he's the paladin, an almost-cartoon exemplar of nobility and self-sacrifice.

The degree to which you'll enjoy the book will depend on your ability to enjoy that approach. But when it gets to the second half- Gefhara and his gaggle of allies arriving on the mystery planet where the book's mysteries begin to resolve- everything starts to click and it's an absolute blast.

The Back Nine

If all that sounded a bit negative, note that the Beyond the Black Library series is aimed at folks who, like me, are regular Warhammer readers who might be considering dipping into other IP's because the writers we've enjoyed are doing the same. The chances of me reading a Twilight Imperium book are fairly modest unless I'm wanting to see how a Black Library writer tackles the setting5.

There's not a thing wrong with the lighter tone of non-grimdark fiction. Indeed, I imagine for many Twilight Imperium fans the first half of the book would have been significantly more enjoyable than I found it, filled with lore and references they understand without needing to pull up their phones and head to Google.

But regardless of your level of lore foreknowledge, once you arrive at the book's second half you've got more than enough to appreciate the story as the action picks up and the mystery unfolds. Beyond that- the part that made it fun- was Cawkwell's ability to write sympathetic and enjoyable characters. I may not have started the book with much of an understanding of them, but she still manages to breathe a great deal of personality into her characters which makes for delightful reading.

From the almost-innocent robotic titan 'Junior' to the techno-mercantilist Izt, the irrepressible Suffi An to the more stoic Connor, and the crew of the FSS Orlando, Cawkwell's story was enjoyable but it was the players who stole the show. There's a lot of heart in this book- Cawkwell's affection for her characters is apparent- and once it comes together it keeps you well-invested until the end.

To the editors at Aconyte, I'd encourage you to take a page out of the Black Library playbook and incorporate a sort of boilerplate introduction and dramatis personae in your stories. A simple, two-page reference section noting the different races that populate the world of Twilight Imperium would have made a huge difference.

Here, for instance, is the in-game bio for Harrugh Gefhara:


The former Quieron created a galactic financial network, enriching all who participated in it. Especially the Hacan, who quietly retained control of their creation.

Short, simple, but illuminative. For a smaller property with fewer avenues of accessibility, the better bet is to assume that not every reader coming to your world is intimately familiar with it.

Overall, this book is best situated for readers who are already fans of Twilight Imperium, but there's enough here to make a few new fans along the way. If Aconyte commissioned a follow-up book with Gefhara, Izt, Junior and the gang (which they should), I'd find it a snap-buy.

Footnotes

  1. Fantasy Flight's founder, Christian Peterson, was the sole designer of Twilight Imperium's first edition.
  2. Two of them, Empire Falling and Empire Burning, were notably written by Black Library veteran Robbie MacNiven (Oaths of Damnation, Void Exile).
  3. To be clear, I consider this an editorial choice, not a writer's one. If Aconyte wanted a book that took the time to fully onboard the new reader, that's entirely their prerogative and Cawkwell would have delivered. Ultimately, what goes to print isn't up to the author, but rather the editor.
  4. Hey, I was a kid. My appreciation would come later.
  5. That's not a knock on Twilight Imperium at all, nor quite so stark a line for some of Aconyte's other properties. Having writers like Josh Reynolds and Evan Dicken writing Legend of the Five Rings is like chocolate and peanut butter, and I haven't even gotten started on the crazy bench depth they've assembled for Arkham Horror. David Annandale's The House of Night and Chain was not only an extraordinary audiobook, but it set a very high bar for what he's capable of in that space. It's mainly that as a principal book reviewer for Goonhammer my dance card stays pretty full.
