The naaru are wise beyond our understanding. I've learned more from A'dal in the last five months than all the years I spent in the libraries of Dalaran.
I am Khadgar, former apprentice to the fallen Guardian, Medivh. I'm sure you've heard his name before.
It was I who discovered that Medivh had been possessed by the Evil One, Sargeras - and that he had opened the Dark Portal between this world and Azeroth. Though I honored my Master, I was forced to slay him and put his tortured soul at rest.
I fought alongside Lord Anduin Lothar as we drove the Horde from our lands on Azeroth. As the heir of Medivh's legacy, I could do no less.
When the call finally came to invade this grim world - and put an end to the orcs' evil forever - I stepped forward along with my friends Turalyon, Alleria, Danath and Kurdran.
My comrades and I called ourselves the Sons of Lothar - in honor of the greatest, most selfless man we ever knew. We gave our all to defeat Ner'zhul and end his madness.
As this doomed world fell apart around is, we shattered the Dark Portal to prevent any further harm befalling our beloved Azeroth.
