The 'Keeper of the lake' was that time my favorite. Good for farming Poetics, nice music, and very much fun end game. Also loved 'World of Darkness' for it's fun 24P play, and where Angra Mainyu always steered up the raid.

At the moment l favor 'The Aery', and especially 'Saint Mocianne's Arboretum' for it's beautiful piano play.
