During the quest to reclaim Erebor from the dragon Smaug, many Moria Orcs gathered at the Sorcery Hill within the center of the stronghold, drawn to the presence of the Necromancer (Sauron). They began to forge weapons and armor in preparation for their master's war in the east region of Rhovanion. After Gandalf was imprisoned by Sauron, the assembled force of orcs set off towards the region of Erebor, to wage war on the unsuspecting Dwarves, Elves, and Men, currently there. Like any other foul breed of orc, the orcs brought along terrible creatures of war with them. Huge and monstrous war trolls as well as flesh starved wargs joined the massive orc host.

During the Battle of Five Armies, Azog's host of 30,000 strong Guldur Orcs clashed with the allied forces in the valley of Erebor, and within the streets of the ruined city of Dale. During the day long fight, thousands were slaughtered at the hands of these orcs, the battle only being won when Thorin Oakenshield killed Azog at the precipice of Ravenhill, thus cutting off the commanding head of the orc army. The orc army was thus defeated, and lost a considerable amount of their forces; only a small number managed to escape the battle.



Much like Azog himself, these orcs were a more disciplined and dangerous breed. They were tall, long-limbed, brutal, bloodthirsty and "bred for war". The Guldur Orcs were heavier-built and larger than the orcs that took over Erebor during the War of the Ring, though their armor and weapons are similar. Most were hive-minded brutes that worked directly under the orders of the one currently in charge of their forces. When their commanding officer was killed, they would completely lose all methods of strategy and organization.
