Warmonger-Tribe

The Warmonger-Tribe (Orc."Kutum-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.Most likely descendants of the Fighting-Orcs, the Kutum-Hai delighted in the cult of war and battle and were the most militaristic, disciplined, well armed and organised of mordor's tribal confederations.After Saurons return during the years of TA 1980-2002 the remaining Warmonger-Orcs were reorganised and redistributed into newly founded Tribal coalitions where their masters found them useful to rebuilt mordor's military and breed improved races of warrior orcs, such as the Black Orcs and Uruk-Hai.
