It appears that I was hasty in my earlier post. I had completely forgotten about the scene from book one where Charlie's Archons ended turn in the Airspace of Gobwin Knob. They were unable to engage any unit that was not in Gobwin Knob's Airspace. Breath attacks probably wouldn't work while the units are up in the air. The Atrium's building probably counts as being on the ground.
So, it looks like the fall and decrypt strategy is the only thing that will let the dwagon armada attack the ground. Perhaps I shouldn't post at 2 AM in the morning.
I think I should probably edit the wiki and add the information from text update 25, to mention that a courtyard can be enclosed in a building instead of the garrison walls, and that such a zone is called an atrium by Jetstone. This is kind of important information missing from the wiki.

I'm pretty sure if GK takes all three of these, then Jetstone is either already neutral or Slately is learning how to use a jetpack the hard, fast, and fun way.
Actually, Spacerock does have a dungeon. It just does not have any tunnels.
Book 2 Text Update 25 wrote:Most Level 5 cities were designed with some unique or augmented feature. Some designs emphasized outer walls or tower or tunnel structures, often at the expense of other parts of the city. Spacerock had dungeons, but no tunnel zone at all. Instead, it had an unusually ornate and well-defended Garrison. Its outer structure was not merely a wall, but a full twelve-story palace complex of rooms and chambers.
