The leader is scared of you and trying not to show it. Barker is all the Intimidation you will ever need, being a growling and watchful Wookie. Navir is just keeping his guard up, blaster ready.
And yes, Bart is correct.
The radio tower looms ahead of you. You are somewhat surprised that it is broadcasting as nothing appears to be powered on this part of the planet. More Maltites appear from the ruins, similarly armed, and watch as the group escorting you passes through. At the doors of the radio tower, guards appear. They do not stop you.
The inside of the radio tower is ruination. Upkeep has been totally ignored as evidenced by peeling wallpaper, fallen panels, frayed and disgusting carpet, water damage, signs of fighting. The Maltites are leading you deeper inside this foul-smelling building.
