Orcs, also called Orsimer in ancient times, are sophisticated barbarian beast peoples of the Wrothgarian Mountains, Dragontail Mountains, and Orsinium. They are noted for their unshakable courage in war and their unflinching endurance of hardships. In the past, Orcs have been widely feared and hated by the other nations and races of Tamriel, but they have slowly won acceptance in the Empire, in particular for their distinguished service in the Emperor's Legions. Orc armorers are prized for their craftsmanship, and Orc warriors in heavy armor are among the finest front-line troops in the Empire, and are fearsome when using their berserker rage. Most Imperial citizens regard the Orc society as rough and cruel, but there is much to admire in their fierce tribal loyalties and generous equality of rank and respect among the sexes.
The Hero of Daggerfall reported Gortwog gro-Nagorm united his people by establishing an autonomous enclave, and forced the Emperor Uriel Septim VII to recognize Orsinium as an equal of the other lesser kingdoms (such as Daggerfall or Sentinel).
Their religion centers around the worship of the Daedric Prince who governs outcasts, Malacath.
Orcs also make excellent warriors who excel in combat with Blunt weapons in Heavy Armor.
Orcs are goblin warriors that were created in the First Age of Middle-Earth by Melkor, an evil Valar (read, demon with godlike power), who captured a number of Elves and tortured and maimed them until they became Orcs.
