Stasia Fallshadow is a Forsaken mage who had a special talent for translating ancient tomes. Around the time of Onyxia's death she arrived to the Pools of Vision, where she used a scroll that she had received from an orc shaman a few months before in Outland. It was a prophecy about the savior of Azeroth. Stasia saw visions of the assassination of Llane Wrynn by the hand of Garona. Garona birthed a child that she gave to Meryl Firestorm. She immediately set out for Duskwood where she attacked Meryl and Med'an but instead captured and brought to in Ahn'Qiraj.
Later she and Garona led a force of Twilight's Hammer cultists in an attempt to kill King , Prince , Warchief , as well as abduct in Theramore. She only succeeded at the last count, using magic to subdue Med'an. She was the first one to predict him to be the "savior of Azeroth", and that whoever controls the boy will hold the key to Azeroth's fate. She tried to get Garona killed but did not manage to do that and took captured Med'an to Cho'gall.
Garona then told the location of Med'an and the blood elf with teleported to Ahn'Qiraj, where Valeera killed Stasia and rescued Med'an.
