The Vanishing of Aegwynn
Sargeras, now within Aegwynn, was slowly twisting her thoughts. She became more distant from The Council; rarely being see by them. Sargeras amplified fears she had already had about The Council. The Council had been using its powers to manipulate the politics of the Eastern Kingdoms. They believed they had the power to prevent war suffering, for the greater good. Aegwynn believed the constant manipulations would end in disaster. She decided to not relinquish her roll as Guardian, for fear that The Council could elect a new weaker Guardian they could control and manipulate. They did not completely approve of her decision to stay on as Guardian but they allowed it for the moment.
Her relationship with The Council would become more distant over the centuries. Hidden from The Councils watchful eye, Aegwynn constructed The Tower of Karazhan. The Tower acted a siphon for ley lines Aegwynn could gain power from if needed. She would also use The Tower as a refuge when avoiding The Council of Tirisfal. As older members of The Council passed new younger ones would join. These new members want to force Aegwynn to give up her powers. They formed the Tirisgarde, an order of magi armed with ancient relics they could use to subdue Aegwynn. For years The Tirisgarde had searched for Aegwynn till they found her refuge at Karazhan. She sealed Karazhan so The Council could never gain control of it's secrets and fled to the ruined city of Suramar where she would hide for hundreds of years; all the while keeping an eye on The Council of Tirisfal.
The Birth of Medivh
Aegwynn would on occasion leave Suramar to watch The Council. It was one of these times that she was finally caught by the Tirisgarde Magi, Nielas Aran. Aran would use various artifacts at his disposal to nullify her magic and slow her down. Over the course of several months the two came at odds. However the fighting would end when both realized each other's true nature. Aran learned that Aegwynn was not the traitorous rebel The Council made him think she was. And she learned that Aran also loathed political manipulations The Council had been carrying out.
It was not long before the two fell in love. They agreed they must work together to prevent the Council from controlling another Guardian. They decided to create an heir and pass on the title of Guardian to. She gave birth to a son she named Medivh. She locked her powers and knowledge of The Council within Medivh where they could manifest upon maturity. Aegwynn soon left Medivh in Aran's care. She went into hiding watching her beloved Medivh from afar. Upon reaching the age of 14, Medivh went into a coma after an explosion of power that had emerged from Medivh killed his father Aran.
Medivh awoke twenty years later, assuring the clergy of Northshire that he was in full control of his powers. Aegwynn suspected that something was amiss and her suspicions were confirmed when she watched, in shock, as Medivh made pacts with the Burning Legion and brought the orcs to Azeroth.
Aegwynn confronted Medivh seeking to turn him away from his chaotic course and back to the Guardianship for which he was intended. When he refused her she attempted to battle him but, having given all her power to him so long ago, she was defeated. It was then that Medivh revealed all to her.
As he died in battle before her, Sargeras had spirited his essence into Aegwynn's own body like a cancer, lying in wait for her to conceive as he knew she would. Sargeras later stitched himself into the fabric of Medivh's unborn body so that when he awoke and realized the power of Tirisfal he would also manifest his unholy, demonic heritage. Somehow unable to kill Aegwynn, Medivh instead banished her from his sight.
In a desperate attempt to spread word of Medivh’s evil, Aegwynn had an audience with King Llane. She warned him that Medivh was behind the orcish invasion and that he would eventually have to be dealt with. Llane listened gratefully. (This may have been retconned in The Last Guardian, where it was Khadgar and Garona Halforcen who revealed Medivh's treachery)
Aegwynn, knowing that she had done all she could possibly do, watched the events unfold before her. She watched her son die, the fall of Blackhand and Gul’dan, and her last testament was a praise to the Alliance before she left to prepare herself for her death.
