From the publisher's website: "Original Edition Characters is a player’s supplement for Labyrinth Lord. An alternate method of creating characters is introduced, with character classes more similar to the way they were presented in the original 1974 rules. Welcome back to playing fighting men, clerics, magic-users, halflings, dwarves, and elves that can be fighting men in one game session and magic-users in the next. This book is a self contained guide to making characters in this style, and will require the Labyrinth Lord core rules."
