The Hollow Hedge

The Hollow Hedge zone went live with the 2009 Nights of the Dead celebrations. Entrance to the zone is at (same as Cauldron Hollow entrance), just off the docks of Nektulos Forest. Like The Estate of Unrest, the zone itself is the quest. Entrance to the zone is controlled by the access quest A Nightmarish Illness.
As you walk through the zone you will find many aggro mobs (e.g., evil harpies, scarecrows, zombies), equal level and usually 1-2 down-arrows. Non-aggro spirits will wiz by you and as you kill mobs, your health increases to enable you to kill epic mobs solo at the end! 
Attackable shinies harvest a holiday collection; they become aggro upon harvest! There are a few chests hidden within the maze, and an optional quest-- click to show the walkthrough below! 
==Notes==
#In order to kill the last epic mob easily, you must kill most of the mobs in the zone! So, unfortunately, it's not a good idea to invis your way through the whole thing, even though you can.
