Eh, I think Razsageth's story is over. Her purpose was to introduce and free the other three, mainly Iridikron. If we run with the idea of Khaz Algar being a part of or near Avaloren, I imagine it's a possibility the "storm" is part of whatever has stopped sailors from going to the other side of Azeroth.
@Arafel, maybe it's time to give that hype train a ghastly green hue.
