Warcraft: Orcs & Humans

The Kingdom of Azeroth was relatively peaceful and ruled by King Llane. That was until a powerful mage named Medivh commanded forces that opened up a portal in the Swamp of Sorrow, leading to another world. This ushered in the Age of Chaos, as Orcs were summoned to this world and attempted to establish an empire. As the Orcish hordes swarmed from the portal, they met with the Humans of Azeroth and battles ensured. Peaceful co-existence is not an option. Only one race will attain dominance over the land.
