Chapter IIb: On Your Own

It's possible to enter your specific life signs into the computer to make an exception for them when scanning for people. If you do that, the computer will not detect your location when scanning for you but the pirates can very quickly remove this block if they discover it.
You could also try to reboot the whole sensor array, taking it offline for an hour or two. You would need authorization by a Verdun Engineer, however, or you would have to hack your way into the system

Alex, you don't have to roll for that. He's not resisting

Lorq, you set it up so that the information gets transmitted on repeat and you manipulate the sensor so it won't pick you up. If you're lucky, that will keep them from finding you at least for a while.
But they will notice the beacon and they will probably send someone down to Engineering to check it out. You should probably hide

Lorq, you check Engineering for alternate entrances and find that there are many. While there is only one door, access tunnels lead from here to.everywhere on the ship. If the pirates are willing to climb through them, they would easily find their way to you.
Zephyr, you try to access the intercom but accidentally set off a hacking alert.
The three of you, as well as everyone else on the ship, hear the ship explain how there was an unauthorized access to vital systems from main engineering.
Now they definitely know where you are
