The Whisperer in Darkness

"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. But Yuggoth, of course, is only the stepping-stone. The main body of the beings inhabits strangely organised abysses wholly beyond the utmost reach of any human imagination. The space-time globule which we recognise as the totality of all cosmic entity is only an atom in the genuine infinity which is theirs. And as much of this infinity as any human brain can hold is eventually to be opened up to me, as it has been to not more than fifty other men since the human race has existed."

H.P. Lovecraft
