Just a note about the Archons: I don't think they're going to survive this fight.
From a strategy point of view, I cannot see them escaping from Spacerock's Tower defences. We've been explicitly told that if you're in the Airspace, you can be hit; there's no way to dodge, the best you can do is change the order of who will get shot by which attacker. So if they remain in the Airspace, they cannot get out of the line of fire. It's not possible.
What's more, I also cannot see them getting out of the Airspace. They don't have mounts, so
The Banana Exploit won't work. And they absolutely cannot move from one Zone to the next, which is the whole point of their current predicament. The only loophole that's even remotely plausible is that they can "stop flying" and let themselves fall, at which point they can "start flying" and catch themselves. Even if this is possible, and I see nothing to suggest that it is, it still won't work - if the barrier between Zones is the ground, then you're still in the airspace until you touch down. And if you "stop flying" until you touch the ground, that's something generally known as "falling". That'll dust 'em.
And yes, they could join all the Gobwin Knob units in a power-dive toward the holes in the Atrium roof, to lessen the height of their fall. Of course, when he sees that, and if he has more brains than a week-old ham sandwich, Tramennis is pretty much just going to order the Tower to fire everything they have at the diving Airforce. The Archons don't have armour or strong defences, they've (presumably) got fewer hits than the dwagons, and of the entire Airforce, they're the least valuable - decrypted Warlords that can't be resurrected twice, and of course the two casters, are more valuable. So the Archons will pretty much be the outer layer of the meatshield when those defences go off, which means goodbye to them.
And then there's the story point of view. If Spacerock falls, and Slately croaks, Jetstone is finished unless an Heir is named. And most of us seem to be in agreement that Tramennis will
probably survive. And how could Jetstone suddenly get all the schmuckers it needs to promote Tramennis to Heir at the last possible second? Why, croak all those Archons, of course.
Either way, while I don't think we can discount them from the fight entirely, I sincerely doubt that any tactics involving the Archons' survival needs to be debated.

But of course that's just my opinion.
