Outlaw-Tribe

The Outlaw-Tribe (Orc."Narlaug-Hai") were one of several orcish tribal confederations in which the Orcs of Mordor had split after the Fall of Barad-dur in the War of the last Alliance.The Narlaug-Hai were rebels, cast out by the other tribes they had formed a tribal coalition among themselves, living the lawless and anarchic life which seemed to suit them best.Of all mordorian tribes they were the one less organised and least hierarchic. After Saurons return during the years of TA 1980-2002 the remaining Burgul Orcs were reorganised and redistributed into newly founded Tribal coalitions.
