Trials of Nyarlathotep
Something black in the road, something that wasn’t a tree. Something big and black and ropy, just squatting there, waiting, with ropy arms squirming and reaching… It came crawling up the hillside…and it was the black thing of my dreams—that black, ropy, slimy jelly tree-thing out of the woods. It crawled up and it flowed up on its hoofs and mouths and snaky arms.
