The Hedge Maze flags the raid for The Lair of Terris-Thule. Keep Thelin Poxbourne alive while he walks the maze and collects dagger pieces.
Access
In Plane of Tranquility Sick Bay, hail Adroha Jezith and say tortured by nightmares.
Find Thelin Poxbourne in the northeast of Plane of Nightmares, across the river inside the hedges. Each room holds 24 players. Group leaders say I am ready to port in. Once everyone is inside, hail Thelin and say I am ready again to start the walk. Thelin gets Spirit of Wolf when the event starts. Unstarted rooms warn, then clear themselves. Success and failure remove players, pets, and leftover hate.
Rooting Thelin and mem-blurring him keeps him from aggroing or wandering.
Path
Thelin collects dagger pieces around the maze. Waves get larger as he goes. When he reaches the fountain in the center, A Construct of Nightmares spawns.
Loot the Dagger Blade Shard from the construct and give it to Thelin. Hail Thelin to zone out and receive the flag. That flag opens the Lair of Terris-Thule portal in Plane of Nightmares.
