These three books by William C Dietz are a prequel series to the Legion of the Damned series. Here is the publisher's summary. I'll return to my thoughts after these messages ...
Many (many) years ago, I discovered role-playing and Dungeons and Dragons in one of the after school clubs. It revealed a universe that allowed me to flex my storytelling muscles and enjoy a mixture of fantasy and sci-fi and feed the escapist dreamer inside.
Over time, I played (and story-led - marked with *) many systems including Call of Cthulhu*, Shadowrun, Dungeons & Dragons*, Middle Earth, In Nomine*, Bushido, Chivalry & Sorcery, Chill, Warhammer, Warhammer 40k, Gammaworld, Hawkmoon, Stormbringer, Immortals*, Marvel Super Heroes, Paranoia, RuneQuest, Vampire: The Masquerade*, and a couple of systems my own devising (Medieval* and Parody*).
I explored live-action role-playing – eventually running my own club and developing my own LARP systems (Fools Gold and Dream Conquest) – and usually found myself in script-writing or game-master duty, writing over 500 individual live adventures over the period (usually weekly), many linked into the world events of the fantasy land we created. I also volunteered for Curious Pastimes and Lorien Trust at their main LARP events (special effects at the Ritual Circle), and did a little script work, cameos and improv for Curious Pastimes. I was also the South East's Editor (UK) for the LARP magazine The Adventurer.
I was also the artistic director for English Heritage for their live Halloween Horrors events at Fort Amherst in Kent from 1998-1999.
The rest, as they say, is history.
