Tolkien created an entire world for his stories, Arda, where Middle Earth is located. Bilbo whips out his sword, cuts the binding and kills the spider.
He is red and gold with fiery breath and long claws. He knows of another path, the elf path, through Mirkwood, that will lead them right to the base of the mountain. Before they leave, though, they find the hidden cache of weapons the trolls had stored.
Just as Bilbo is about to sit down to a nice breakfast, in rushes Gandalf. The next day Bard and the Elvenking tell Thorin they will exchange the stone for a share of the treasure.
After spending the night in safety, they resume their travels east and Gandalf takes them to the house of Beorn, the skin-changer, who outfits them for the next leg of their journey, through the forest of Mirkwood. Shortly after escaping the spiders, the unlucky dwarves are captured by a group of wood elves who live near the river that runs through Mirkwood.
