Agatha

Agatha is a Val'kyr in service to the Dark Lady.

Edge of Night
Agatha was present when Sylvanas Windrunner almost committed suicide. Annhylde the Caller and Agatha tried to stop her. Agatha, being the youngest of the battlemaidens in life and the most impatient in her undeath, tried to convince her by reminding her of the Forsaken, though Sylvanas did not care.

Cataclysm
Agatha is the first person new Forsaken players meet, as she is the one that raises them back into the world of the "living".

She is present for the meeting between Garrosh and Sylvanas, where Sylvanas reveals that the Val'kyr have joined the Forsaken. Agatha then resurrects the nearby fallen corpses as Forsaken, much to the disgust of Garrosh and High Warlord Cromush.

Agatha later helps the player by taking them to Fenris Isle and aids the player in fleeing when the refugees from Hillsbrad become worgen. Agatha later appears in Sepulcher and The Forsaken Front where she aids in the resurrection of Lord Godfrey and his lieutenants.

When Lord Godfrey betrays and kills Sylvanas, Agatha and her fellow Val'kyr Arthura and Daschla sacrifice themselves to resurrect the Dark Lady.
