He doesn't swim naked, so he takes the summon anyway.
Cam takes to the air, takes pictures, disintegrates industrial complex bits, and looks for where the aliens may have scurried off to.
Luckily, Cam can fly, and the lack of anything else whatsoever makes it really easy to spot the two other portals available. Presumably the aliens went through one of those.
Of course someone does! That's promising. Cam hauls the rest of the way through, takes a few pictures, disintegrates weapons.
Cam wonders if they're made of Real Physics or Actual Substances, but doesn't let this wondering distract him too much from indirectly blowing shit up. These aliens are really fond of their self-destruct mechanisms.
Cam is going to need to make a map. He starts a map. He goes back and sticks his head through the other fork out of Ex-Industrial-Park.
Do these aliens want to talk if he makes a speaker and yells at them?
How many portals out of here?
He thinks he's cleared enough of a buffer zone to go back and notify the clam planet people though.
He makes a new comm. "Hey there!"
"Hi! So the aliens really, really don't want to talk. They want to shoot ineffectually at me and then blow themselves up. A lot. There's a maze of spheres past the next one - it forks into two, and then one side's got five and one's got six, haven't gone farther than that yet. Do you have anything resembling a guess of how long it would take me to convince all these aliens to self-destruct?"
"That's likely to depend on how many there are, and we've never been able to determine that beyond 'always more'," says Azair.
"I mean more like how long would it take me to navigate the entire infested maze of Spheres. How many portals is it customary to have."
"Anywhere from a handful to hundreds. It's a very individual thing. And I have no idea what state these Spheres were in when the Enemy got to them - it's possible their owners tried to close as many portals as they could... it's also possible they didn't get the chance."
Cam makes a wired hookup between a thing and another thing on each side of this near portal and goes to the far side and says, "Testing."
"Okay, I'll just leave a trail of these relays as I go. You will probably hear explosions. It turns out when their weapons and industrial parks disintegrate they often blow up. Deplorable workplace safety standards."
"It'll get really tedious eventually but I do like being helpful and these aliens are really emphatic about being unwilling to entertain the possibility of receiving help, so it's all you guys."
