"This booklet contains all the information you need to create a centaur player character for Labyrinth Lord or Advanced Labyrinth Lord (and is easily adaptable to other OSR systems). Details include both a centaur race and a centaur racial class, as well as information on creating centaur bands and camps. 12 pages (6 pages of content)."
So lately over the last three weeks we've been looking into possibly going back to OSRIC as a possible alternative OSR retroclone rules set. And one of my players has expressed a more then a passing interest in using a Centaur PC. And that's when it struck me James Mishler Games sent me a copy of the Centaur Race by James & Jodie Moran Mishler. Centaurs have certain connotations within Advanced Dungeons & Dragons first edition games as Dragon magazine paints them in solid Sylvan & Fey terms. James Mishler keeps this set of expections; "Centaurs are a sylvan race of forest and meadow. They tend to be atavistic and live in primal harmony with nature, abiding with dryads, nymphs, satyrs, treants, and other woodland folk and creatures. They tend to eschew contact with non-sylvan, non-fairy races, preferring to live in woodland and meadows in the wilds. Generally, males are wandering warrior-hunters while females are gatherers and gardeners who tend to the young. Males are also known for being wild and violent, especially when confronted with anything from the outside world; they sometimes raid settlements, especially for wine, which they consume with much gusto"
The Centaur racial type or PC class or race could easily be adapted into OSRIC with little issue allowing the race to become a part of are campaigns.
The Centaur Race from James Mishler Games centers its subject matter and focuses itself on only on the PC essentials & little else. And this appeals to the player from the ground up.
