Just so everyone knows - with a big population like that and on this short of notice, they aren't going to be Shifted in. Or if they are, a decent part of them are going to have Shift Afflictions. Seriously, I've been Shifted out of this barrier for a draft I was supposed to be on from a point other than that thing in the tunnels and I was vomiting most of that day.

So most likely, they're going to be escorted through the barrier physically... so they'll be way out at the edge of the forest. [Or... some will be sick. Both are possible]
