Anessa

The Mistress
Lady Anessa Morningsong was a high elven Priestess of the Holy Light, who died during the Scourge invasion on Quel'Thalas. She stemmed from a noble family, renowned for their accomplished Arcanists, and was the first in her lineage to study religious teachings. In life, she was a firm supporter of stable relations between Quel'Thalas and the human nations, and caused a minor scandal by marrying a human commoner. Lady Morningsong was known for her stern, yet highly effective teaching methods and was loved by her small flock of students.
In undeath, she now serves the Lich King as a Banshee.
