...around Merrilor and around Thakan'dar. They cannot Travel.

All the Light's channelers are now free. They need some rest, but the Shadowspawn won't get very far within a week or two, and with the new tricks with Gateways, they can be monitored.

Both armies of Shadowspawn are in a predicament. The former Blight has been all but emptied by now. It can't sustain them, they'll be forced to go on the offensive. The other army at Merrilor is similarly caught. Shienar has burned, South there isn't much of anything before the region of Tar Valon. There's only Arafel.

The Trollocs at least are a fairly minor problem. Within weeks at most the males will have been largely exterminated, the rest is a matter of locating their breeding camps in the Blight, which can now be done with Gateways. Fades can get away (if the Bore being sealed still let them travel through shadows), but they're sterile and the Trollocs gone there won't be any new Myrddraal. The Dark Hunt has been dealt with. That leaves residual Draghkars, and the other creatures of the Blight.

Not that big a problem. A few will probably survive, pockets of Shadowspawn might surface for years, but it's nothing that can't be dealt with.
