The Unforgiven

The Unforgiven (named Lylia in life) is an elite wraith in Stratholme. Not much is known about The Unforgiven, but some have mentioned her mask is a truly powerful item.

History
She was a former champion (presumably of the Light) who committed heinous acts against innocents in Stratholme in the name of gaining unholy power.

Dungeon Journal
''Lylia was a blade of righteousness among her people. After Arthas commanded his forces to purge the city, her sanity was ripped apart from seeing countless innocents die by her hand. She fell on her sword to escape the madness around her, and she now exists as a spectral being forever denied absolution for her heinous acts.''

Strategy
She isn't alone, so be prepared for a fight. She will spawn when you walk past an archway after you take right turn after the rat gate trap, near Hearthsinger Forresten. The Unforgiven spawn is scripted, so have your party members rest before going any closer to the archway. Some non-elites spawn too, but a mage can take care of them easily. The Unforgiven casts Frost Nova now and then. Very easy fight.

Objective of

 * Retribution (quest)

Inspiration

 * This mini-boss could be a reference to the Metallica song "The Unforgiven".
 * Her background is also similar to those of the Deathlords.
