The cover of Heirs to Merlin

Heirs to Merlin

Heirs to Merlin is the book of medieval England and Wales for Ars Magica. This was my first full book. It is the source book for England and Wales, and contains no game statistics at all. Instead, I focused on ways to bring medieval history into a game, without turning it into a history lesson. […]

Cover for Fallen Fane

Fallen Fane

Fallen Fane is a live-action Ars Magica scenario. It was written to be played by a couple of dozen people in an afternoon at a game convention. For a few years, at the end of the twentieth century, I was writing about one of those per year. Fallen Fane was the last one I did, […]

Corellon Larethian

Corellon Larethian is the chief deity of the elves in the Forgotten Realms setting for Dungeons and Dragons. The Forgotten Realms setting was released when I was a teenager, and I have loved it ever since. In a lot of ways, it is the classic RPG fantasy setting, and I like those settings, particularly the […]

Cover of Love and War

Love and War

Love and War is a sourcebook of knights and chivalry. I was asked to write this book on the grounds that I know a lot about the subject. I can’t think where people got that impression from. Anyway, my goal here was to get away from “knight=fighter in shiny armour on horse”, and look into […]

The cover of Akrasia


Akrasia is the goddess of wasting time on trivialities. Akrasia is the goddess who tempts people to have just one more beer before going home, to enjoy the good weather rather than fix the roof, to play one more round of cards before getting back to work. She seems unthreatening, and some people even wonder […]

Cover of Splintered Peace

Splintered Peace

Splintered Peace is about saving a city from itself. This was an attempt to do something a bit different. There are hordes of attacking orcs, and dealing with their leader is an important part of the adventure. However, the main problem is the growth of racial tensions within the city, and that cannot be resolved […]

The cover of Black Monks of Glastonbury

The Black Monks of Glastonbury

Black Monks is an adventure setting in medieval England. The books describes Glastonbury Abbey, in the west of England, with lots of mythic Ars Magica detail. The adventure premise is that most of the monks of the Abbey have become devil worshippers; as the Abbey itself still contains one of the holiest places in England, […]

Cover of Power and Privilege

Power and Privilege

A sourcebook detailing the fictional Rosicrucians for the WitchCraft game. The brief for this book was to include no new mechanics, which meant that I had to include interesting background material. My goal was to design a group that would work well both as player character and as antagonists; the Rosicrucians were not presented very […]

Cover of Ars Magica Fifth Edition

Ars Magica Fifth Edition

Ars Magica is the roleplaying game of medieval magic. Best Rules Best Production Values Best Game Ars Magica Fifth Edition is, obviously, a revision of Ars Magica Fourth Edition (on which I did a lot of work; see below), which in turn was a revision of First through Third Editions (on which I did no […]

Medieval Player’s Manual

This is a guide to roleplaying in medieval Britain. OK, I don’t need to ask why Green Ronin thought it would be a good idea for me to write a book about the Middle Ages. Indeed, the president of Green Ronin wrote to the president of Atlas suggesting that he should really be charging an […]
