Casters are used to casting in battle, and from what I can tell casters in a thinkamancer link are even less aware of their surroundings. I'm sure Charlie could manage to keep Vanna focused even in the face of a whole wing of dwagons bearing down on her.
Erm... Charlie was woried about Vanna being asked tough questions while she was standing around. I'm just gonna assume a casting is harder then standing and dwagons are more distracting then tough questions.
Charlie´s a busy man--or tuna. He's got a lot of balls in the air. If he is indeed forming a link with Vanna, as would appear to be the case, then it's a tribute to his power and skill--or to the power of the arkendish--that he can retain a good amount of his individuality and handle other varied tasks. What more do you want from the man--or tuna?
Communication with the dish was gone and the archons could not contact Charlie. He was able to delegate to the archons, but Charlie appeared to be out of comision.
At the end, I am reluctant to believe that a spell that affects and entire side, with an effect that in a sense encompasses not only all of Gobwin Knob and Jetstone but any other sides involved in this conflict, across who know how many hundreds or thousands of hexes, has such specific requirements in terms of its focus or target.
The volcano was a powerful game changing spell, as was trioxin. Both had difficult to fulfill requirements to be usable. The volcano spell which wiped an army is almost impossible to use, and apperenlty is usable in a handful of hexes. Trioxin which was easier to use simply required a large number of corspes in one hex.
Just because something is powerful does not mean it is usable freely and easily. Frequently a powerful and effective technique is highly limited in its application.
But you are making one unfounded assumption, that Wanda entered Spacerock from the same exact hex from that ground troops would have to cross.

That's assuming that any Erf units needed to even be in the hex or "at close range." Given the "range," if you will, of the Kingworld spell, I'm not sure I buy the need for the immediate presence of enemy troops. It seems to me that the basic assumption that a parley was needed to either distract Wanda or buy time. That seems improbable. Why not just sock Vanna away in the dungeon, for example? That would surely have bought her enough time. And if it even took so long that it would have roused Wanda's suspicions, why not at least put Wanda inside the tower, as opposed to the relatively visible and exposed parapet?
They need the enemy troops to be able to cast off-turn. Also if they could sock Vanna away some place safer:
why didn't they? Your soon to be attacked by an enemy with foolamancy, who mught swoop on you with out your knowledge and your sitting out in the open? If she could cast from the dungeon thats where she would be.
Actually, I'll even say that the parley was over and what was broken was a truce. After all, they had already ended negotiations...
This makes things better how? Breaking a truce the turn its formed?
