When thirteen dwarves arrive at Bilbo's house, they told him the story of their ancestry and why they're going on an adventure. And it started like this. So long ago, Thorin's far ancestor, Thrain the great, moved up North to the Mountain. He moved in, and he built great mines, tunnels and workshops, where he also found lots of gold and jewels. Later, his grandfather, Thor, became king of the Mountain. He was gaining in fame and fortune, and was sent from mortal men to send his smiths to create golden works of art. Soon, everyone in his kingdom was filled with gold and valuables. But soon enough, disaster stricked. A greedy and dangerous dragon named Smaug came in and murdered a majority of the dwarves. He first landed on a nearby mountain near the Mountain. The nearby dwarves were close by, and ran for their lives, and to warn the others. The warriors came through the gate, but Smaug was waiting for them. He burnt all of the soldiers. He then did the next part of the scheme. He crept in the Mountain, and killed every living dwarf in there. Nevertheless, he took every last bit of gold, and slept on it, guarding it with his life. On the other hand, the surviving dwarves hid in fear in the forest. They cursed and wept for their home and gold. Thorin, his father, and grandfather had to earn a living, and they didn't have much money. They earned lowly jobs of blacksmithing and coalmining. But unfortunately, Thorin's grandfather died, and his father lost his memory, and only remembered the map and key that will lead the way to this adventure. Thorin remembered everything, and he has been waiting for the day when he will avenge what was taken from his family.
