Gul´dan

Darkness Incarnate, Destroyer of Dreams Former member of the Stormreaver Clan, Gul´dan had a natural gift for the dark arts, becoming a warlock for the Shadowmoon Clan pretty early on in his life. Weak towards the whispers of power he became a pupil of the dark titan Sargeras and has plotted to summon him ever since. After the events of Warlords of Draenor he escaped towards the current timeline and proceeded to initiate his master plan to summon Sargeras.
