Hermes Serpent wrote:"In the last years of Denethor I the race of uruks, black orcs of great strength, first appeared out of Mordor, and in 2475 they swept across Ithilien and took Osgiliath. Boromir son of Denethor (after whom Boromir of the Nine Walkers was later named) defeated them and regained Ithilien; but Osgiliath was finally ruined, and its great stone-bridge was broken. No people dwelt there afterwards. Boromir was a great captain, and even the Witch-king feared him. He was noble and fair of face, a man strong in body and in will, but he received a Morgul-wound in that war which shortened his days, and he became shrunken with pain and died twelve year after his father. "
Yes, this is an excellent find Hermes Serpent & leads to all kinds of plot possibilities. Morgoth used at least some of his thralls to work toward a variety of ends (which could have conceivably included weapons/armour), so I so no reason why Sauron couldn't have done the same thing. A rogue or enslaved Dwarf or Elf labouring in Minas Morgul or Dol Guldur provides a great villain - or a tragic hero, fallen or otherwise. Ditto for Saruman.
