Editing Warcraft: Orcs & Humans (section)

===Backstory===
The Orcs originate from another world. A warlike species, they conquered everyone else around them, and eventually, the various Orc clans started scheming against one another. The Warlock clan, noticing these developments, tried to find a solution and prevent the Orcs from turning on one another.  The Warlocks noticed a rift between the dimensions and, after many years, opened a small portal to another world. One Warlock explored and found a region, called Azeroth by its Human inhabitants, from which the Warlock returned with strange plants as evidence of his discovery.<ref name="refManOrcStory">[[#refWOHManOrcMac|''Warcraft 1 Manual: Orcs (Mac)'']], pp. 17–20</ref>

The Orcs enlarged the portal until they could transport seven warriors, who massacred a Human village. The raiding party brought back samples of good food and fine workmanship, and a report that the Humans were defenseless. The Orcs' raiding parties grew larger and bolder, until they assaulted Azeroth's principal castle. However, the Humans had been training warriors of their own, especially the mounted, heavily armed Knights. These, assisted by Human Sorcerers, gradually forced the Orcs to retreat through the portal, which the Humans had not discovered.<ref name="refManOrcStory"/>

For the next fifteen years, one faction of Orcs demanded that the portal be closed. However a chief of exceptional cunning realized that the Humans, although out-numbered, had prevailed through the use of superior tactics, organization, and by magic. He united the clans, imposed discipline on their army and sought new spells from the Warlocks and [[Necromancer]]s. Their combined forces were ready to overthrow the Humans.<ref name="refManOrcStory"/>
