Stasia Fallshadow is an undead mage who - at one point - abducted 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 was killed in Ahn'Qiraj by Valeera Sanguinar when the latter and Meryl Felstorm teleported in to rescue Med'an.
She led a force of Twilight's Hammer cultists in an attempt to kill King Varian Wrynn, Prince Anduin Wrynn, Warchief Thrall and Garona Halforcen as well as abduct Med'an. She only succeeded at the last count, using magic to subdue Med'an.
