Feldon 
From the EQ2 Forums:
The minions of Lord Vyemm call the Halls of Fate their home. This fortress is one of the most important places to The Awakened. As such, the Halls of Fate and the treasures within these walls are guarded diligently.
Within the walls of this massive fortress, the Doomwing Legion toils to create draconic weapons. Hidden within the laboratories of this dungeon, you may find the secrets behind the creation process of the weapons. But beware! Dragons do not respond well to intruders!
The Fabled version of the Halls of Fate dungeon becomes available to players starting Thursday, January 23, 2014. Gather a group of the top adventurers you know and get ready for this upcoming heroic dungeon. Do you have what it takes to defeat the Doomguard Legion?
