The Gates of Thelgrim

A Descent: Legends of the Dark Novel

By Robbie MacNiven

A reluctant trio are forced to investigate a mystery city, but in doing so find themselves fighting a demonic atrocity, in this staggering action novel set in the epic fantasy Descent games.

When three separate adventurers are hired to investigate the recent sealing of Thelgrim, the great Dunwarr dwarf city, all three have misgivings. One is a wanted criminal and the other two have no wish to work together – but when the money is this good, it’s hard to refuse. As the three head to Thelgrim by secret path, none of them know what awaits them. Terrinoth is in upheaval: new threats are rising, and this one comes from the dark.

Terrinoth: an ancient realm of forgotten greatness and faded legacies, of magic and monsters, heroes, and tyrants. Its cities were ruined and their secrets lost as terrifying dragons, undead armies, and demon-possessed hordes ravaged the land. Over centuries, the realm slipped into gloom… Now, the world is reawakening – the Baronies of Daqan rebuild their domains, wizards master lapsed arts, and champions test their mettle. Banding together to explore the dangerous caves, ancient ruins, dark dungeons, and cursed forests of Terrinoth, they unearth priceless treasures and terrible foes. Yet time is running out, for in the shadows a malevolent force has grown, preparing to spread evil across the world. Now, when the land needs them most, is the moment for its heroes to rise.

Interviews and Articles

“But a fun romp with an unlikely band of adventurers through dangerous depths is the aim of the game, so hopefully that’s what readers enjoy.”

– Robbie MacNiven



“I would very strongly recommend this book to any fantasy fan because it hits all the right notes, and is a great standalone book with little dependency on any previous knowledge of the franchise.”
Big Geordie Geek

“From the start I was hooked, as is nearly always the case with these books. The characterization was brilliant. Anyone who enjoys Descent, Tabletop RPGs or Fantasy would, I believe, instantly be intrigued and hooked.”

– What You Tolkien About

“Expertly-written and populated with some of the most memorable characters in a fantasy novel that I’ve read in quite some time, and imbued with a bold, thought-provoking and often surprising narrative, with an emotionally powerful ending that’s akin to a fist in the gut.”
– SciFi and Fantasy Reviewer, on The Doom of Fallowhearth

“Great character work is delivered over the course of a plot that starts off slowly, introducing characters, ideas and locations, then explodes into action and never lets up. MacNiven maintains a tone throughout that’s brilliantly appropriate to this world – First Team really does feel like an X-Men story pulled straight from the Marvel archive.”
– Track of Words, on First Team

“This is a tight, fun little read that feels incredibly fresh… This utterly drips with comic book energy.”
– The Omniplex, on First Team
