I thought the level 70 white mage quest was fantastic. It's one of my favorites.
The final quest was poignant and touching. It was the compelling story of a mother consumed by the fear of losing her child, and how that fear ultimately dictated their lives, and how one's lack of emotional control can lead to self-destruction. And the final battle was fantastic. The demon was terrifying, and the accusations it made were even worse. For a child to have to hear all that and overcome it takes incredible fortitude. It's a message of prevailing over the most intimate of tragedies and their psychological repercussions.
I commend the writers of that story. I thoroughly enjoyed it.
