The module “Dagorlad and the Dead Marshes” lists a trio of Dark Lieutenant characters.
Thuringwathost (as its inhabitants call it) is a grim formation of rocks SE of the Dead Marshes. It has always been a place of mystery and terror for the natives of the area. If one were bold, cautious, and foolish enough to creep up to it, get past the steep walls of natural rock, and the sentries to look within, one would find a paradox: a lovely little garden with a pond, benches, and trees. This is Miruimor’s private haven, and few who see it ever see anything else again.
Miruimor – Black Numenorean mage – 20th level – 20 CO/30 MA
Having grown up in Umbar named Firailian, she was a fervent believer in Sauron and his Black Temple, but held a deep scorn for those of her own race. When the temple master tried do away with her due to her belief that she should be the leader, Firailian, now known as Miruimor, tipped off a rival temple as to the Black Temple’s location. The ensuing battle slew the high priest, and Miruimor fled north, settling in Osgiliath disguised as a noblewoman from Pelargir.
Her great beauty had her courted by many fine men, including the army commander of the area who told her pillow secrets that should have only been told to the Steward of Gondor. One night, Miruimor dreamed of a dark, powerful figure of black with only nine fingers standing upon a hilltop of Southern Mirkwood. She awoke knowing her god and inspiration was alive and well in Dol Guldor! Eventually arriving at the gates, she demanded to speak with the Necromancer, but Khamul had her imprisoned therein. When the nazgul interrogated her, she referred to Sauron as the “Lord of the Rings” and attracted the Dark Lord’s attention.
The next day, the avid pupil met her Dark Master alone. No one knows what transpired in that throneroom, yet Sauron was pleased and amused by her presumption. He had plans for her, as he needed an agent in the south near Mordor which he was planning to reopen. Miruimor was told to set up residence at Thuringwathost to serve as an waystation for Orcs and Trolls transitioning onwards into Mordor, out of Mannish sight. As a private joke onto her, knowing her scorn about her own race, he assigned Black Numenoreans to serve as her lieutenants.
Herudor, a promising captain at Dol Guldor was to serve as her Lord of Arms, and Feagwath, a lesser Nazgul would inspect the fortress from time to time and also act the part of the Necromancer to her troops during those visits to help keep them in line. Miruimor had a rich selection of magical items including a staff of lightning, demonskin armor, and a magic broadsword named Morlach.
I will update with Herudor and Feagwath soon, as they fit closely with Miruimor.
