The communication from moran is distorted. He says something about one of his droid units (which he is using because they cannot be mind tricked) found them at one of his checkpoints. Then the communication fizzles and goes dead.
BTW, there is no-one in the room by the lift (which is to say you cannot sense anyone in there; there is a door between you and reception). Majora must have entered the lift with Ascar.
There is danger here. You can sense movement beyond one of the other doors out of this room.
BTW, remember that the astrolabe is half as high as a man and very heavy
You can't use the lift while it is still taking Ascar down, Xeth!
You can hear the sound of many footsteps coming this way.
For reference, if you look at a plan view of Ascar's office:
Reception is throgh a door at the top right. The museum is at the bottom right. Ascar's desk is at the top, his bar at the top left. The windows overlooking Malastare are at the top. The doors you can hear movement behind are at the bottom left.
Gundark and Mah are currently in the museum, looking at the astrolabe.
Xeth is in through the door in reception, where he has found out the lift is still in use.
And I will say that Sierri and Lance are by Ascar's desk.
There is a loud noise as suddenly three hover-cars pull up by the windows outside- two for the main room and one for reception. Each has three men, one wielding a large repeating laser gun mounted to the vehicle.
They start to spray fire into the room. The windows shatter instantly and an enotmous barrage of laser fire starts to sweep across the room, each gun taking a different third.
Kellan pushed mah down to the floor and threw herself alongside him, drawing her sabre. "I sure didn't invite them," she hollered back to Xeth over the noise of the laser fire. "And I don't think they're Ascar's cleaning staff." She looked at mah. "We can't drag the Astrolabe out of here," she shouted in frustration. She half crouched on her knees, adjusting the workings of the Astrolabe and trying to make sense of what she was looking at without getting her head blown off.
After the first sweep has finished, blowing most of the office apart and leaving you guys prone and sprawling, the doors at the bottom left burst open. People dressed in what seems like military uniform and bearing a variety of weapons start to rush in, the hover-cars giving them covering fire.
Lance and Xeth (as the warriors of the group you get these insights), you are up against professionals here. This was planned well.
