Wanda, it occurs to me, might actually be safe. It counts as a fall if your mount is killed and you fall across the boundary, but what happens if you let yourself fall on a live mount? Simply tell it to stop flying and let gravity do the rest?
The fall could almost certainly kill her dwagon, but if she's riding a live dragon when it actually hits the ground, it might only count as damage against the dwagon, or provide her with some sort of safety net (ie, if you fall on a live mount, you can be incapacitated or injured, but won't die). She and anybody else on the dragons as they fall might actually get off damage free, which means it' s just a matter of decrypting the mounts. It's up in the air, as it's a mechanic the world has probably never had to deal with before, because everybody knows you can't do this! Of course, everybody knows you can't effect multiple hexes at the same time, and that warlords can't go into the magic kingdom...
My theory, btw, as people have been using these threads to speculate, is that Parson will in fact pull off the amazingly good win. Why do I think they'd do this, making them "unstoppable" again? Because GK isn't about to get that unstoppable. this is just one side of the coalition, and if it goes bad here, all the halfhearted joiners will get deadly serious (possibly including one Caeaser, the possible new TV head, who is starting to get that everybody should have taken GK more seriously). And Charlie is still actively working against them, and Jillian is probably going to take a huge chunk out of them while they are committed here.
But the big thing, the Chekov's gun that simply hasn't been fired yet is still sitting on the shelf from book one, and Charlie and Jillian are in fact the people to fire it off.
Jillian actually knows what parson is. Charlie knows what parson can do. After this turn, they might communicate a bit more and get the whole picture of him. Including HOW he was acquired.
Charlie has capital, and great relations with magic kingdom, who's already nervous about Parson's side.
Which means that a very special scroll of PLOT might soon be used, and specify "bring us warlord/s who have BEATEN parson"
At the very beginning of the story, Parson was about to go up against his friends in an epic new war game. That might still happen.
(Edit, that would be like, the cliffhanger at the very end of book 2, I mean that speculation long term)
