The group leave the elves, and continues their journey against Erebor to slay the dragon.
The group falls into a hole in the ground and get trapped by orcs!
Bilbo manage to get free from the orcs, and he is now alone in the many tunnels in the mountains, when he suddenly finds a golden ring.
Bilbo meets the owner of the ring; Gollum, he is a creature who lives in the caves and eat dead orcs and raw fish.
Bilbo uses the ring to get invisible and escape the caves, the rest of the group manage to fight their way out.
The pale orc has a personal goal; kill Thorin, because he chopped his hand off once.
The eagles saves the group from the orcs, and fly them to a safe spot.
Thorin almost died during the attack, but Gandalf manage to save him in the last minute.
