Major pulls out his electronic binoculars and has a good look at where they are at the moment.
Uhura stops and decides to analyze the elements of this place to find out what its made from. If Major doesn't see anything dangerous she will follow his lead.
Specific Action: Artemis attempts to create light, using her communicator, and her Electonic Repairs skill
Artemis digs through her backpack, and finds her communicator. Then she attempts to rig it so that it will emit light (It has to have some kind of screen, right?)
If that works, she can secure the communicator to her cap with some strips of cloth from the blanket she keeps vandalizing. If that doesn't work, she'll just hold the comm in her left hand, and the axe in her right.
Using her comm light, she cautiously forges ahead.
Specific Action: Artemis will catch up with Seth so he doesn't plunge to his death.
In Character: : "Look, guys! I've rigged the thingie so it... Hey! Where's Seth going?" Artemis hurries after him. "Seth! Don't go wandering off! You could have plunged headlong into disaster, and...that's... My job."
As long as she's there, she takes a quick look at each doorway.
