Robert E. Howard 
Cthulhu Tales [EPUB ebook] 

The true gods of Earth existed long before our ancestors crawled mindless upon the shore: Yog-Sothoth, Shub-Niggurath, Nyarlathotep… insatiate, tenebrous monsters, whose ultimate throne is Chaos.
Greatest of all is he called Cthulhu. Only in ancient, blasphemous manuscripts can that name be found… and those who decipher it are left pale and numb, aware that in the very act of decipherment they have become both pawn and prey of an ultra-worldly power that renders human existence both tenuous and trite.
The Old Ones were, the Old Ones are, and the Old Ones shall remain… long after they have devoured us.
