From the introduction:
This is a compilation of house rules, errata, notes, and details of interpretations that I as DM employ in running my fantasy campaigns. I have also included a variety of articles and commentary I have selectively chosen for its quality and similarity to my personal views from a variety of sources. The majority of my gaming experience is based on the traditional 1st edition AD&D rule books and other core material. I have customized and elaborated upon these rules over the years to become tailored to my gaming preferences, style, and personal tastes and have codified my personal variations in my version of the Player’s Handbook as an accepted set of house rules I will DM. This said, I have found at least a few additional game mechanics that I feel comfortable using in my campaigns, any of which I consider valid and all of which can be used to adjudicate the interaction in my campaign world Multiverse based on the consensus between myself and my players.
