In a mist-shrouded past, long before the time of the first chronicles, there was a world called Azeroth. All kinds of magical creatures shared these lands with the tribes of people, and peace reigned everywhere. But one day, the terrible demons of the Burning Legion, along with their evil master Sargeras, the dark god of chaos magic, invaded Azeroth. Under the influence of the demonic Fel, dragons, dwarves, elves, goblins, humans and orcs have entered the struggle for power over the scattered kingdoms.The Guardians of Tirisfal are the divinely empowered defenders of Azeroth, who for generations have waged a secret war against Burning Legion. One of them, Medivh, was destined from birth to become the greatest and most powerful member of his noble order. But even in his youth, the darkness stained his soul, defiling its purity and turning to evil the one who should have fought on the side of good. Medivh's struggle with the evil within her became fateful for all of Azeroth... and forever changed the world.
