"Don't mind him, laddie." Balin spoke to both Bilbo and the dwarf twins. "Thorin has more cause than many, to hate Orcs."
Kili gave Maleficent a grateful smile, nodding thankfully at her.
Bilbo looked after Thorin with a sad expression. He felt sorry for the dwarf, he was always so angry all the time, he couldn't help but wonder what had happened in his life to make him that way.
"After the dragon took Erebor, King Thror tried to reclaim the ancient dwarf kingdom of Moria." Balin explained. "But Moria had been taken over by legions of Orcs, led by the most vile of all their race; Azog the Defiler."
