Jeapa nods at the fourth helper, smiling grimly but warmly, and she points at Floats on Thunder and then at, lastly making a gun-finger gesture at the door. "Help him cover the othahs, mate," she says, in her strange singsong accent. Eli, who is holding a rifle opposite the door. Awuim, helmet firmly and enviably attached (you can bet his ears aren't bleeding) waits by the main corridor, keeping an eye lookout in case of... well, it's probably a good strategy.
She jogs down the hallway to a system terminal. A laser scanner recognizes her and she sets a security override to open the doors even though the place is on decompression lockdown. Her finger hovers over the touchscreen and she glances your way, making sure that you're all ready. Once AJ's blaster is in place (where his hand was a moment ago), she taps the screen.
The doors part slightly, and a hiss of air jets fiercely into the hallway, covering Eli and Floats with a shower of tiny, glinting particles, like metal filings. After a few seconds, and a loud metallic crash inside, the air equalizes and the doors swing inwards, open.
The room is a machine shop of some kind, full of workbenches, and odd mechanical tools. You can see a number of lathes, grinders and welding kits, and a number of unusual apparati.
There are four people in hard vacuum suits inside, one of them on the floor underneath a large industrial press which has toppled onto him (T1). Two of them are loading a large device, full of electronic readouts many of which are flashing alarming shades of red, onto a trolley (T2 and T3). The fourth (T4) whose back is to you, is madly grabbing at a system terminal to keep him/herself from toppling over backwards on her/his stool. All of them have large guns belted to their legs, except the one under the press whose blaster rifle is in his left hand.
Diego and Eli's actions will occur first, then the thieves, then AJ and Floats on Thunder. Jeapa will spend her action moving.
