Narcrabor was born into the Gwibdolar Easterlings, or Black Market, 44 years ago. He lived a simple life as a courier and task-doer for Black Market until the Rohirrim-Easterling war, in which both of his parents were killed before him. Growing vengeful, and losing the instinctive command to treat others well, he began to work his way up through Black Market and general Rhunic society, earning the title of Warlord of Rhun and Marshall of Black Market. After the death of Irad Gwiberskarn, Narcrabor was elected the next master of the Witherland, and has ruled there since. He is known for carrying a rare disease, known as Brainstorm, which seems to cause him intense migrane-like headaches now and then. He is thought to have contracted it in Eregion.
