The Arkenstone does nothing. In fact, the only reason the dwarves want it back is because it is a great treasure and a magnificent jewel. It was discovered beneath the roots of the Lonely Mountain and is also known as the heart of the mountain.
Because long ago Thrain I had found it at the roots of the lonely mountain and the dwarves cut and fashioned the gem.
Bard keeps the arkenstone and will give it back to Thorin later if he can receive part of the share
Bilbo snuck out of the Dwarves camp and delivered the Arkenstone to Bard.
Gandalf was looking for someone to share in an adventure at the beginning of The Hobbit.
There are so many conflicts. The goblins of the Misty Mountains were a huge conflict, but also the wild wolves, the giant spiders, the wood elves, and of course the most important conflict of all, Smaug the Great Dragon.
If you are referring to near the end of the book where Thorin rejects Bilbo, it is because of a dwarf's greediness for gold and treasure. Thorin had been searching for the Arkenstone of his father, Thrain, in the Lonely Mountain, and was upset that he could not find it. He was shocked when he found out that the very Hobbit that the dwarves had put all of their trust in had betrayed them and found the Arkenstone and did not tell him. Bottom line, dwarves are greedy. Hope this answer helped. :)
yes
The Arkenstone is the jewel of main focus in The Hobbit, and it's a prized treasure among the dwarves.
The Arkenstone
Bilbo took the Arkenstone from Smaug's treasure trove. He gave it to the men to use as a negotiating tool.
It is the most prized jewel of the Dwarves
Smaug has the Arkenstone in his hoard. Bilbo acquires it from the pile of treasure. He then gives it to Bard. Bard puts it with Thorin when he is buried. That is where it stayed.
kill em.
He was entombed under the Lonely Mountain. He was laid to rest with his sword and the Arkenstone.
Bard keeps the arkenstone and will give it back to Thorin later if he can receive part of the share
Bilbo snuck out of the Dwarves camp and delivered the Arkenstone to Bard.
He forgives Bilbo for stealing the Arkenstone, and then tells Bilbo that everyone should be like the hobbits: more concerned with comfort than with treasure. Then Thorin dies. He is buried with the Arkenstone, and Dain, Thorin's cousin, is proclaimed the new king.
