Speak with Nozdormu at the End Time.
Nozdormu, the bronze Aspect, has asked for help from the champions of the Horde. You are on his short list. I can share few other details.
It is uncharacteristic of my master to request the assistance of mortals, but I suppose that all things change with time... even the Aspect of Time himself.
He awaits you at the End Time, in the distant future. I can help you to travel there, if you so choose.
