apart from the referenced female being Azhara or Sylvanas or Alleria (strongest contenders imo) or some other outsider ( Xalatath ? Moira? Chromie? w/e place it here).
apart from the boy king being Anduin or Bolvar or Wrathion or w/e.
Xalatath boldly states that for millenias void forces been seeking access to the realm of the seat of the pantheon and now they have gained it. And Argus during Magni scenarios and when he awakens is all but fel corrupted. What he mentions sounds like words and thoughts of a void corrupted soul.
And the whole bunch of the titans are imprisoned in the seat. Hell that was some strong victory for the void and noone noticed it.
