Namek
The drone carrier dispatches 6 stealth drones which seem to be kitted with heavy equipment towards the location of the site. As they approached, they split into pairs and activated their special equipment used to disguise them from varying detection methods, rendering them invisible. They find a hidden spot nearby the facility and slowly land, releasing their cargo. Several minutes later, after all preparations ar ecomplete, they began building something out of it, assembling it all together into a 3 meters tall and 2 meters wide object made of black, metallic material. After working on it for some time, they finnaly finish it. With their task completed, 4 of the drones land at the base of the machine and attach to it, draining their power and giving it to the mysterious machine. Soon, a fain sizzling noise could be heard as sparks start to appear randomly in its immeadiate vacinity, with the remaining two drones occasionnaly circling around. Soon, a part of the machine reveals itself to be some sort of sliding door, as something slides it to reveal a what was inside:
The figure stepped out, breathing heavily. They looked around a bit and then closed the door behind them. Some dozen seconds later, another noise was heard, and the door was opened yet again to reveal another man inside:
The figure stepped out again and nodded to the one that came before it, then they closed the door and the cycle repeated.
When it ended, there were 6 of them that looked like the second figure, and one the sole recon specialist. They made several prepparations, and lastely checked their specially kitted watches that could grant them full invisibility as well as some other tricks that would certainly become very, if the right situation presents itself.*
