Probably fair to say that the quote:
Seems to be straightforwardly a command to The Watchers from Alexstrasza during the time of her departure though, no?"The world has been sundered. It cries out in pain. We must go to it's aid. We entrust our ancestral home to you, The Watchers. Let the land slumber. Hidden even from our own eyes.
You will feel our return in the waking of the land. Then, you must light the Beacon of Tyrhold, lest the path home be lost to us."
and that's why the end is awkward because I think, who is she talking to?
But I definitely don't rule it out that the Isles could be Isles to begin with though. Could be a neat idea for sure.
