Garret moves as far up as possible. If it's the second turn, he moves again.
Gillon eats the emerald and moves 2 spaces up. If it's the second turn, he moves 2 spaces to the left.
Kilika uses Fire Rain to attack the entire area north of Garret, at least 1 cell away, including the airship (I assume this won't create Fire Ground, since it's snow, and so on?).
