A monstrous spider who lairs in the tunnels of Cirith Ungol on the borders of Mordor, the last surviving offspring of Ungoliant, the great spider of the First Age. Shelob has dwelt in the mountains of shadow since the Second Age, feeding on all living things that pass through her domain. Gollum leads Frodo into her lair, hoping she will kill the Hobbit so he can reclaim the Ring. Sam wounds her with Sting and the Phial of Galadriel, driving her back into the darkness.
