Gabriel brought to my attention a post in a dungeonmastering board he reads, which detailed the circumlocutions some people go through trying to square their plans for a vibrant scenario and the Received Wisdom of official campaign materials. It might be because we think of every event, action, sentence, or phrase as something to pervert for our use, but I was made genuinely distraught by the notion that those books - which are suggestions, at best - would conspire to dilute your joy. Those things are tools, and what's more they're your tools, which means that they serve you. Our version of the base setting is practically unrecognizable. Rule Zero is invoked constantly, of which Assertion Twelve is a corollary.
