Orcs are hostile species and the major antagonists in the Realms of Arkania, which is both a pen-and-paper roleplaying game as well as a series of video games set in the same universe - they are based upon the creatures of folklore and are the avowed enemies of humanity and its allies as well as a scourge upon all civilizations due to their piratical raiding and tendency to wage war for the most petty of reasons.

Blade of Destiny

In the first video-game based on the pen-and-paper roleplaying game the Orcs are the central antagonists, usually warring amongst themselves they become united under a powerful chief and gather an army numbering in the thousands and plan an invasion that could destroy the civilized world: calling upon the courage of heroes (player-created parties) to brave a series of quests in order to stop the Orcs and secure victory from the jaws of death.
