Think that might require a pretty heavy investigation of Realmgate War series, but basically anyone that got tied to one of the Winds of Magic in the End Times "survived" in the sense their soul seems to have become bound to it. Allarielle didn't magically travel through space to wind up in Ghyran, the Jade Kingdoms, she awoke and created it, and unless Nurgle or some power completely overpowers and absorbs it into the Realm of Chaos, she will exist as long as it presumably does.
