Antagarich
Antagarich is the continent on which most of the action in Heroes 3 and its expansions take place. It is located on Enroth (planet).
History
Most of Antagarich was once ruled by the Wizard-Kings of Bracaduun. A legendary Barbarian, Jarg, united all the tribes of the Wastelands (Krewlod) and conquered the entire southern-half of Antagarich. However, after he died of old age, his heirs squabbled for the throne and dismantled the nation in their squabbles, allowing the Wizard-Kings to rise again and reestablish their empire. They oppressed Barbarian culture especially, attempting to suppress the history and legend of Jarg in fear that heroes would try emulating Jarg; and had nearly succeeded in that task when Tarnum rebelled and repeated history.
Tarnum, however, was not as wise as Jarg. His reign was especially ruthless and brutal, forever twisting Barbarian culture, and Tarnum himself turned out to be as much a tyrant as the Wizard-Kings were. Rion Gryphonheart would soon lead an uprising against the Barbarian King, and vanquish him in single combat. With Tarnum's death, his empire crumbled quickly, allowing Rion Gryphonheart to create the new nation of Erathia which quickly dominated most of the continent.

Trivia
Antagarich is sometimes spelled "Antagrich" in official documents such as the Shadow of Death manual, notably in the description of the Pixies and Sprites, Halflings, Rogues, and Trolls. Greg Fulton coined the name "Antagarich" as a portmanteau of "antagonism" and "rich", connected with an 'a' to make pronunciation easier. A continent rich in antagonism...
