Utûgi
The Elder Orcs, fashioned in the pits beneath Zíkar by foul craft of Morgoth. Memory of them faded over the passage of centuries; even the name that was given to them, Utûgi, brought to mind only dimly-remembered images, unfamiliar and indistinct demons of the ancient world.
The Utûgi possessed a size, strength, and cunning that Sauron coveted but could not replicate; the Orcs he bred in later years could not match those that belonged to his master, and that deficiency rankled. After a long slumber they have been awoken together with their masters at the fall of Sauron.
Background
The Utûgi are based on the first generation of Orcs bred by Morgoth in the Elder Days. In The Silmarillion, these were said to be corrupted Elves, though Tolkien explored several possible origins for the race of Orcs throughout his writings. The term "Utûgi" is unique to The Lord of the Rings Online.
