Greatmother Ankha has asked you to collect enough Gjalerbron Cage Keys to free 10 Gjalerbron Prisoners. Return to her at Camp Winterhoof when you manage to do so.
10x Gjalerbron Prisoner Freed
From the little we know, the vrykul are conducting unnatural rites in an 'awakening' ritual to the west in Gjalerbron.
They're using living sacrifices to fuel their rituals.
[player], you must stop this. It matters not who or what is in those cages, they must be freed. I would guess that the vrykul hold the keys.
The last thing we need is more of those strange vrykul threatening us, or worse, them wakening something even more evil....
