A Great Spider and daughter of Ungoliant, Shelob was among the original residents of Mordor and remained there even after Sauron made it his domain. For a long time, she was the "pet" and lover of the Dark Lord, until he cast her aside and forced her into the mountains.Since that day, the distraught Shelob sought to take revenge on Sauron and paid no heed to his demands, letting her brood spread beyond Cirith.
