Eh, then just fly towards the wall and check the area for anything interesting.
Keep telling people to evacuate to the evacuation points and move away from the capital building. Also tell them that this area is now under our control and that any hostiles should surrender.
Edit: If people do surrender or are otherwise unable to fight, destroy their weapons and send them away to evacuate. Having people that survive tell the others that surrender is an option may increase the chances of others surrendering.
If someone is too injured to evacuate, then ask someone else (civilian or one who has surrendered) to help them evacuate.
The wall? Well it's quite large (hey now) and clearly quite old. This wasn't created by the invading former UWM, this was something native they took over. It's been refinished and painted white but the brief and anticlimatic battle has revealed sections of the underlying stone. A stone wall this high must have taken a great deal of time and effort; no doubt the ruling class here wielded a lot of power. Especially considering how seemingly ornamental this is.
Most of the civies are gone, the only ones left are those running out from the capital building itself and they've decided to hoof it across the steep natural rock slope rather than down the stairs your team is occupying. Fair enough, gets them out of the way at least.
Once surrendering people/POW's are gathered together, disarm them if needed, then open pocket dimension to a holding cell and dump them in there. Dump their weapons and stuff into a separate room.
Then check out the gate area more closely. That wall, does it obscure vision much? Could it be used as a good chokepoint? Could cameyes see someone trying to hide behind it? Basically trying to decide if we should leave it be or destroy it, so need some more info for that.
The only people left behind now are civies. No one from this outer area seems to have surrendered. At least no one you can find. No one alive, for that matter.
The wall and gate could be used as a good chokepoint to prevent entrance into the capital compound, and it is tall enough to obscure your view of the entire area beyond it, save for the small glimpse you get through the gate itself.
No, cam eyes can't see through 20 feet of stone.
Gently place down fellow robot overlord Renen, maybe patting him on the head affectionately. Find a good high spot with open sight lines to anyone who might be approaching the fortress from without.
You set renen down. He squirms out of your grasp and shoots off, back up the stairs. Cute little murderous robot.
The best place you can find that has both high ground and a view of the area outside is the gate and the wall itself. You could go land up there and keep watch but that would make you a pretty big target to anyone on the outside.
