I think the Seanchans have divided their forces into two. One Heading for the White Tower (over that plain in the norht) and the other going for Gheldan and all the other lands in the south. The force in the north is probaly going to "get" the WT. Remember AH didnt manage to take them, but the S are his precessors. They will probably win (Mins viewing), they are better prepared than AH, they have Suldames, all those beasts and besides 50 Aes Sedai are going to attack the BT. This will make Egwen the one and only Amerlyn seat. The force in the south are going to face Perrin! And later probably Rand too. The outcome there will be a standoff (I belive). Then Mat will solve it diplomaticly (marrige, the old way). For our dear Tamerlyn who dont belive in fairytales and think there will be mor chaos. Look at all the other places Rand has bean, there will be Seanchan darkfriens and rebels! But Rand and the Seanchans will unite!
