Ariel follows Asari.
4 She sends her searcheyes and quickly finds the small nodule of floatstone, buried around two meters deep. It seems to be the size of two fists, and traces of cracks and scratches in the rock around it tell her that it was artificially implanted, confirming it as their objective. She tells Eric.
Falken walks up to the wall Asari's searcheyes are floating around. He kicks the ground and watches little dust motes float upwards. It seems that is floatstone. The bluish particles slowly slowly rise up, from his legs to his chest-height, to his eye-height, to over his head, and eventually stick to his lightcube. It feels quite calm right now.
Eric 4 slowly digs into the rock, ordering his sentry to man the gun. It will take two turns to mine all the way to the floatstone. The rock shrieks as the metal bits of the drill spin and chew into it. Rock powder mixed with water is spewed out from the hole. The monotonous sound of wrecking rock echoes through the cavern.
On the other hand, it feels like there's a rumbling that isn't caused by his drill. It's slowly growing in magnitude. Feels like a train underneath the rock. It might just be him, but the shadow around the light bathing them seems to shrink, or tremble, and the night is looming, oppressive, dangerous. It might just be him, but his lightcube dimmed. It might just be him, but the drill's sound has taken on an urgency, as if the mechanical, magitech circuits of the sentry detect something the dull humans haven't have.
Falken, Ariel, and Asari feel something like a hand gripping their chests, tightening and threatening to burst.
Jurial looks around. They are in multiple pools of calm yellow light that is illuminating a smooth rock floor. There is a wall, where Eric's sentrybot is working to extract their objective. The space around them is roughly open, with the wall being flat. The cavern seems to widen here again, become a T-junction, or maybe end.
