Black Uruks

The elite Black Uruks were the greatest orcs Sauron ever had in his armies; made after his diminishing at the end of the Second Age.

Origin
They were originated before the Great Years; used against Ithilien in Mordor before Sauron returned, and that is their only Time-Line reference.

Seregost, a fortress east of Barad-dûr shown in an artistic canonical map of Mordor, is where the Black Uruks came from.

In the Great Years
It is said that the very throne of Sauron was guarded by Black Uruks, and that their captain was the Mouth of Sauron (who was also the non-orc lieutenant of all Orcs of Mordor). Some Uruks were shown at the Orc-camp that Frodo and Sam came upon. At the Battle of the Morannon the highest Black Uruks were killed, in the downfall of the Dark Tower, and that would have included Shagrat, who would have been in that area after delivering the mithril coat to Barad-dûr.

The largest orcs that Sauron ever birthed, they all served him directly. No Black Uruks were at Minas Morgul or Osgiliath.

Notable Uruks of Mordor


- Murgash, Gothmog's second lieutenant at Minas Tirith

- Shagrat, the Uruk taskmaster at Cirith Ungol.

- the large Orc with the smaller tracker Orc, eavesdropped on by Frodo and Sam after their exit from Cirith Ungol, was also an Uruk of Shagrat's company.
