Does this mean the end of the Kor'kron? It appears so. Kor'kron guards in Orgrimmar have been replaced by representatives from all of Kalimdor's Horde races -- Darkspear Guardians, Thunder Bluff Protectors, Orgrimmar Grunts, and even a few goblins wearing the Orgrimmar Bruiser label. The Cleft of Shadow is back to normal, with no signs of any of the events that took place during the Siege. Gamon, for now, is nowhere to be seen -- which makes me wonder if he survived the events of the Siege or not. We'll have to wait and see on that front, perhaps he'll make an appearance in our garrisons on Draenor?
In Grommash Hold, Vol'jin has now taken his proper place as Warchief of the Horde, handing out low level Ragefire Chasm quests and dispensing advice. However, players shouldn't expect any kind of complete quest overhaul in areas that heavily featured Garrosh Hellscream. Silverpine Forest still plays out as it always has, and the heated exchange between Garrosh and Sylvanas remains intact. Let's face it -- overhauling Silverpine, Stonetalon, the Barrens, and every other area that was heavily touched by Hellscream's influence would be a project the scale of Cataclysm ... and frankly, I'd rather see brand new current-level content than another major revamp of leveling zones.
Whether or not that quest content will be re-worked in the future remains to be seen, but it's not really necessary at this point in time, particularly not when the focus of the story has shifted elsewhere. Maybe if we see an expansion featuring the Forsaken in a more prominent fashion, we'll see more changes on that front. Until that point in time, Forsaken players can rest easy -- Hellscream's eyes, it seems, are no longer upon them.
