It's not tied to any particular quest I know of it's just sitting there, waiting to be discovered. Supposedly constructed by the wizard Relvinian with a view to getting daemons to do his laundry, it's a calming, floral little place whose only real perils are the odd troll-under-the-bridge and the nimbus of hellspawn living at its core. Though its appeal has waned somewhat after each subsequent visit, I still hold fond memories of meandering through a seemingly endless tangle of forest and shrubbery - darting past an ettin, a gargoyle, and perhaps less thrillingly, a mongbat - and finding myself at the entrance of a giant hedge labyrinth.
