Know the game systems, and you will know how and when to take upon yourself the ultimate power. To become the final arbiter, rather than the interpreter of the rules, can be a difficult and demanding task, and it cannot be undertaken lightly, for your players expect to play this game, not one made up on the spot. By the same token, they are playing the game the way you, their DM, imagines and creates it. Remembering that the game is greater than its parts, and knowing all of the parts, you will have overcome the greater part of the challenge of being a referee. Being a true DM requires cleverness and imagination which no set of rules books can bestow. Seeing that you were clever enough to buy this volume, and you have enough imagination to desire to become the maker of a fantasy world, you are almost there already! Read and become familiar with the contents of this work and the one written for players, learn your monsters, and spice things up with some pantheons of super-powerful beings. Then put your judging and refereeing ability into the creation of your own personal milieu, and you have donned the mantle of Dungeon Master. Welcome to the exalted ranks of the overworked and harassed, whose cleverness and imagination are all too often underappreciated by cloddish characters whose only thought in life is to loot, pillage, slay, and who fail to appreciate the hours of preparation which went into the creation of what they aim to destroy as cheaply and quickly as possible. As a DM you must live by the immortal words of the sage who said: "Never give a sucker an even break." Also, don't be a sucker for your players, for you'd better be sure to they follow sage advice too. As the DM, you have to prove in every game that you are still the best. This book is dedicated to helping to assure you are.
