Spiders

The Great Spiders The Great Spiders of Mirkwood are very dangerous creatures. Shelob's offspring went from the Mountains of Shadow to the border of Mordor and then to Mirkwood. The Great Spiders had a colony in Dol Guldur. They live in webs and they use them to capture prey and hang them from tree branches after putting posion in them. In 2941, the Great Spiders captured Fili, Kili, Balin, Dwalin, Bifur, Bombur, Oin, Gloin, Dori, Nori, and Ori. Bilbo Baggins killed one of the spiders with his sword, which he named Sting. Bilbo lured the spiders away from the Dwarves and then let them free. At the end of the Third Age, Dol Gurldur was destroyed. Nobody knows what became of the Great Spiders.
