THE ARTHURIAN COMPANION - SPECIAL EDITION
Pendragon
Contains everything you need to begin an epic adventure in King Arthur’s Britain. It covers the complete core rules of the Pendragon game system, including Traits and Passions, Skills, combat, injury and recovery, Glory, Favors, and Honor.
As long as we can find no identifiable, indisputable Arthur, the legend has almost complete freedom to grow, to change, to spread, to be many things to many ages, many readers, many romancers." — from Phyllis Ann Karr's foreword.
THE ANNOTATED LE MORTE D'ARTHUR
Pendragon
This 532 page deluxe hardcover edition of Sir Thomas Malory's Le Morte d’Arthur is edited by renowned Arthurian scholar John Matthews. Marginal notes throughout the text are by John Matthews and by Greg Stafford, renowned designer of the Pendragon roleplaying game.
"This great book contains robust, resonating myths and legends. Both are wonderful but they are not the same things. Myths are the stories on which we base our lives. Legends are a colorful distraction from the grim realities the myths reveal." — from Michael Moorcock's foreword.
LE MORTE D'ARTHUR: THE GRAPHIC NOVEL VOL 1
Pendragon
In 1485, Sir Thomas Mallory penned the epic Le Morte d’Arthur. 540 years later, that story is brought to life on the page with an all-new graphic novel!
The artwork by Tom and Nimue Brown (Hopeless Maine) is at once whimsical and darkly gothic, perfectly capturing the range of the story itself and rendering the world of Arthur’s Britain in a unique style that truly captures the imagination.

RuneQuest - Glorantha
Developed under license by our friends at Slitherine, the RuneQuest: Warlords video game uses the acclaimed engine behind Warhammer 40,000: Battlesector and has been enriched with deeper melee combat. Battles unfold on grid-based maps where terrain, lines of sight, and unit placement shape every engagement. Every biome, settlement, and creature has been meticulously crafted to reflect the history, mythology, and artistry of Glorantha, bringing it alive. RuneQuest: Warlords delivers a fresh tactical experience rooted in the mythic world of Glorantha.
"You know, a very good tactical game set in the best fantasy world ever made can only be a must buy!" — BEO (customer review)

Designed for use with Basic Roleplaying: Universal Game Engine as well as other BRP-powered games.
"Basic Roleplaying: Creatures shows off the breadth of the [BRP] system... it’s also a stealth update for any game that runs off of Chaosium’s d100 systems. This means Call of Cthulhu, RuneQuest, and even Rivers of London all get a host of new creatures." — Bell of Lost Souls
