The article linked by Chris Metzen comes from MovieWeb, a reputable entertainment website.
Please be mindful that this is not confirmation that a movie is officially in the works, as Metzen tweeted soon later mentioning that he's just passing along what he saw. The movie might actually be a reality, as Blizzard legend Chris Metzen has tweeted about it! Of course, before his death, Medivh cursed Khadgar with age and frailty.Rumors about a possible Warcraft 2 movie have been flying around the WoW community for a few days now. Khadgar and Lothar, in the end, defeated Medivh together. Towards the end of the movie, you see Draka place her son on a little riverboat and send him off, but in the lore, Go’el was found among his parent’s bodies, he was then given the name Thrall, and raised by humans. Medivh killed his own steward, Moroes, a name you might recognize from the first mandatory boss in the raid, Karazhan. It makes sense, as mages did not exist in the world of Orcs. Gul’dan was in disbelief when he had heard that the mage had used the fel against them, though the orcs called him a warlock, which is untrue. There is so much more to the story, to make the long story short, yes, Medivh did help bring the Orcs to Azeroth and he was able to use the fel against the orcs. This is only the backstory to Medivh bringing the orcs to Azeroth. Sargeras used him to contact Gul’dan and help bring the orcs to Azeroth. This leads to Medivh’s corruption as he was possessed by Sargeras. After Medivh was born, Aegwynn left him with his father, and Medivh would acquire his mother’s powers, along with Sargeras. Medivh had been corrupted by Sargeras from before he was born, Sargeras after being defeated by Medivh’s mother, Aegwynn, his essence went inside her body and waited. He killed the Orc’s world, and it was the same fel that Medivh used against the orcs that would work its way to destroying the human world. Gul’dan was the first warlock of the horde, the first Orc warlock to have ever existed. Gul’dan is the main enemy in the movie, but this begins with his backstory. No one knew about the brief affair with Garona and Medivh, so it would definitely make sense that Garona and Medivh would have an affair and a son of theirs would show up in a future movie. In order to tell whether they kept true to this, we would need to see more Warcraft movies. At which point, we would be unsure of this at the current time. In lore, Medivh fathered a son with Garona. The young Prince witnessed the death & murder of his father. Varian fought for years to try to understand why his father’s murderer would cry at the moment she killed the King. She was forced to kill the King after she was told to, she was unable to stop herself. Medivh played mind-games with her, so she was unable to form a true alliance with the King of Stormwind. What you may not know is, while Garona is the murderer of King Llane, he is not the one who told her to kill him.
This also proves the kind of king Llane was, a king willing to die to save his people. Though it is true in the movie she was reluctant and did not want to murder him, this was also true in the way of the lore. She was an emissary in the first invasion of Azeroth, and the murderer of King Llane. Though, it has not been revealed what she is exactly, only that she is an Orc that looks different and speaks the common tongue. Garona Halforcen is believed to be half-human/half-Orc, but in reality is Draenei/Orc, at this point, the truth has not been revealed to her yet. Khadgar would play a huge role in the movie’s end plots, just as much as the role he would play in World of Warcraft. He was approximately 17 at the time this happened, so the movie is accurate in the proper depiction of his age. The movie features a young Khadgar, who bears the mark of the Kirin Tor, who renounced his vows. I haven’t been able to find any source that states this or whether or not Gul’dan actually breathed life into Go’el (Thrall) to bring him back to life.
Whether or not Draka almost miscarried Thrall due to going through the portal while pregnant, is a mystery. Blizzard, later on, released Warcraft 2: Tides of Darkness, which is why I believe this is as I call it “The long lost story of Warcraft.” I call it this because, in its failure, hardly anyone knew about a time when it was literally just orcs and humans. Warcraft: Orcs & Humans, did not sell very well, in fact, it did so poorly it was removed from the shelves. This is the biggest clue, that this movie is not based on World of Warcraft, but a time before that. In the beginning, the movie discusses the war between Orcs & Humans.
