The Last Days of the Third Age of Middle Earth/WMG

Umbar and Harad are Token Good Teammate of Sauron.
They act exactly like the other evil factions, but:
 * In-universe they joined Sauron because of an Enemy Mine situation (both are enemies of Gondor)
 * In the game they are the only evil factions which faces, armors, and weapon do not scream "Evil!" at first sight
