Monsters are, as you doubtlessly already acutely understand, terribly frightening and dangerous. Many films have been made, detailing the paralyzingly ghastly and gory imperatives on which monsters operate, resulting in rooms fairly brimming with ichor and carnage: Soggy glumps of eyeballs, hanging from sticky ropes of optic nerves like morbid tether balls; piles and piles of viscera, settling and emitting gas like teams of farting snakes; ripped and abandoned limbs, arms and legs stacked like macabre log cabins of ruined flesh and protruding bone, still twitching and dripping the last of their darkening blood. Every shadowy corner, every looming closet, every rickety and ramshackle basement staircase adumbrates the uncanny atrocities monsters are hoping to wreak. They are eager to wreak. It’s their whole mission, in fact. (There’s a perfectly empirical reason for the word “monstrosities,” and it’s precisely what you’re thinking.)

One might reflect on this reality with floppy despondency, and in fairness, one would not be mistaken to do so. Flop and despond, if you need to get it out of your system. But as you’re able, kindly recover your wits, and devote your attention to the following introductory tutorial on the rules by which all monsters must abide, lest they be subjected to the same harrowing and disastrous fates to which they are so devoted to imposing on the human population.
