Battle of Moria

The Battle of Moria was the last conflict of the War of Goblins and Dwarves.

Prelude
After Thror lost the lonely mountain, he wished to take over the kingdom of Moria. However, unknown to him, Orcs took over Moria. Instead, Thror declared war upon the mountain. Before they went into battle, Thrain entrusted Gandalf the Grey with the map and key his father had given him. However, only Thorin Oakenshield knew of this exchange
