As The Chips Fall
The Seventh Law - Never Seek Knowledge and Power from Beyond the Outer Gates
The universe is infinite, and contains within it multitudes: The world. The Nevernever. Hell, and perhaps even Heaven. Every being and thing within those bounds has its place, even if that place may be horrible beyond mention. But there are Things outside of this universe. To say that they hate the world would be to assume that we can even understand them. It is more accurate to say that they are antithetical to the world. They do not want to destroy the universe any more than a ball you drop wants to fall—it is simply the outcome.
The Outer Gates are what keeps the world safe from such things, what locks them away and keeps them outside—and thus, such things are called Outsiders. They are so alien, so not of this world, that few methods of assault stand a chance of giving them more than a moment’s pause. And the intentions the Outside has for us are so dark, so dire, that the Seventh Law is the only one on the books that isn’t conditioned upon casting a spell. Even doing research on the Outside is verboten, setting aside actually pulling power from there.
The Gates are never fully closed. It’s through the tiniest of cracks that the darkest of things come into our world (like He Who Walks Behind). And when someone does pull power from there, forging a bond with a malevolent Outsider force, one of those cracks widens, just a touch. The human race is lucky that few have ever managed such an effort for long, thanks to the efforts of the White Council a particularly zealous enforcement of the Seventh Law.
