Like many of his predecessors, Ogrod was an unusually large Orc ,as he was of the progeny of Ogslap, who slew his rivals for the throne of Goblin Gate. Due to his tremendous size, Ogrod was able to survive the bloody power struggles common among Orcish tribes and finally assumed the title of "The Great Goblin", or Dûrba-Hai in Orcish.
Ogrod was known to have had Boldog blood, evidenced by his gargantuan stature, more than twice the height of all of his minions and his immense, even obese, form, with his bulbous head which seemed too large for his body, from which swayed a beard-like flesh growth. Although Ogrod was known for his cleverness, cautiousness, and surprising charisma, his explosive temper and swollen ego often troubled his reign.
While ostensibly swearing allegiance to the "Necromancer" (Sauron) and Bolg son of Azog, he and his kingdom remained largely independent. Though he feared that the Dark Lord would "relieve" him of his role, leaving the Ashdurbúk to usurp him, Ogrod remained an apparently "loyal" vassal of Dol Guldur and an "ally" of Gundabad.
Ogrod was described in Bilbo Baggins' autobiographical work There and Back Again, in which he was seen taking the company of Thórin Oakenshield captive, accusing them of being spies, thieves, murderers and friends of Elves. He was finally slain by Gandalf, allowing the Dwarves to escape and the Quest of Erebor to continue.
The slaying of Ogrod reignited the ancient enmity which existed between the Dwarves and the Orcs, causing their many disparate tribes to unite and make preparations for war to secure their domination of the North. A host of Orc tribes loyal to Ogrod assembled at Mount Gundabad and intended to sweep southward until they learnt of the death of Smaug the Terrible and altered their plans so to fit those of Sauron.
