One officer remained in the Alley, their current headquarters. A buzz in his ear, and he received orders.
"G.U.E.S.S. troopers, we need to find the location of Dusk. Send out the jets."
A space marine looked at him.
"You mean the underground base?"
"How do you know it's underground?"
"Because we found it from space."
"... ARE YOU KIDDING ME?"
The officer took the space marines maps, scanning over them. Orbital bombardment. That's what we need.
An hour later, fifty powerful missiles streaked through the air towards the unfinished watchtower, and the ground around it. Stealth technology made them invisible, they had no mind so they weren't cognitive, no investiture to sense, and the stealth tech also prevented scanners from noticing them.
