Warcraft: Orcs & Humans

Warcraft: Orcs & Humans (more commonly known as Warcraft) is a definitive fantasy real-time strategy (RTS) game developed and published by Blizzard Entertainment in 1994.

The kingdom of Azeroth had been peaceful for many generations, and the reign of King Wrynn III was prosperous and free of bickering and infighting, when the events leading to the current conflict between Orcs and Humans began some forty years ago...

559 The child sorcerer Medivh is born of the court Conjurer and a mysterious woman traveler who disappears after his birth, resulting in him becoming a ward of the kingdom at court. 564 Prince Llane, the first and only son of King Wrynn and Lady Varia, is born.

571 Medivh reaches the Age of Ascension, transitioning from childhood to adulthood. On the eve of becoming Apprentice Conjurer of the Court, such power and magiks are unleashed from him that his father the Conjurer is only able to contain them with the help of over one hundred clerics from Northshire Abbey. Even so, the effort costs the Conjurer his life and Medivh is taken to the Abbey after falling into a deep sleep. 577 Prince Llane reaches his Age of Ascension, and Medivh returns to court to repay it for his care. He offers a magic hourglass, claiming that King Wrynn's reign would not fail so long as it did not empty. 583 Azeroth has gradually declined, with crops failing, children sickening and moods growing dark. As the sand in the hourglass runs out, the castle of Stormwind Keep is assaulted for the first time by Orcs, creatures whose origin is as yet unknown to Humans...

584 Llane is pronounced King of Azeroth, and it's clear he must rid the kingdom of these Orcs, as they kill indiscriminately and even those captured have never returned. After nearly a decade they are contained in the swamps, but continue to skirmish in the Borderlands.

593 Medivh's mother returns to court in the tenth year of King Llane's reign with a warning. Medivh had been intended as a vessel for her own knowledge and power once she left this place, but he had fallen prey to other influences. When she sought him out, she found him insane and barely survived her attempt to destroy him, after which she was banished from his sight. Although drained, Medivh remains a threat who can only grow in power...

She also informs the King that Medivh inadvertently brought the Orcs to Azeroth, as a portal opened to their world during his struggle with his father. Orcish Warlocks had found and sought control over a small tear in the dimensional fabric, hoping to find another world to conquer to prevent the Orcish clans from turning on and destroying each other after they had completely and utterly subjugated their own.

Now, raids in the Borderlands are becoming more organized, as a new Orc War Chief, Blackhand, rises to unite the Orcish clans to conquer Azeroth and destroy the Humans...
