Beyond Neptune...

Their main immediate abode is a still undiscovered and almost lightless planet at the very edge of our solar system—beyond Neptune, and the ninth in distance from the sun. It is, as we have inferred, the object mystically hinted at as “Yuggoth” in certain ancient and forbidden writings; and it will soon be the scene of a strange focussing of thought upon our world in an effort to facilitate mental rapport. I would not be surprised if astronomers became sufficiently sensitive to these thought-currents to discover Yuggoth when the Outer Ones wish them to do so….

When I left Brattleboro I resolved never to go back to Vermont, and I feel quite certain I shall keep my resolution. Those wild hills are surely the outpost of a frightful cosmic race—as I doubt all the less since reading that a new ninth planet has been glimpsed beyond Neptune, just as those influences had said it would be glimpsed. Astronomers, with a hideous appropriateness they little suspect, have named this thing “Pluto”. I feel, beyond question, that it is nothing less than nighted Yuggoth—and I shiver when I try to figure out the real reason why its monstrous denizens wish it to be known in this way at this especial time. I vainly try to assure myself that these daemoniac creatures are not gradually leading up to some new policy hurtful to the earth and its normal inhabitants.
