from the introduction:
When James announced his retirement from gaming — hopefully only temporarily — he generously turned over the bulk of his material to me. I've been a fan of his work for some time, and consider it a privilege to be able to carry the torch onward in his place.
This Toolbox Edition reprints the original Core Elements Revised published by James along with a collection of optional rules. These rules, contained in the sidebars and appendices (along with a few revisions in the core rules themselves) will assist gamemasters in customizing Core Elements to suit their campaigns.
I can only hope that this, the first of James' creations that I've had the opportunity to build on, will provide you with some good gaming.
