The huge elevator sinks down into the darkness under the red sands of oxide. After what seems to be a whole life of descending, the platform stops with a deafening screeching sound. In front of the group, there is a huge cavern excavated in the rock, far bigger than the dome itself and almost as big as the whole complex of the surface.

The air is heavy and humid down here, filled with the bitter and metallic smell of blood and charged with the sweet aftertaste of rotten fruit. Row after row of old and rusty mining wagons are lined up facing towards thousands of mine holes scattered around the underground vault.

LIV looks around
-According to the map, this is the extraction area. Both the geolocation of the missing troops and the source material for the compound P1-10 known as “Pixie dust” are located down main tunnel C23-

The group looks around the thousands of signs located on top of the mouths of the different mines until they reach section C a couple of kilometers away from the entrance. A long and twisted stair connects the hundreds of small openings numbered from 1 to 100 dispersed like holes on a cheese block, and it's not long before doctor Bast sits down unable to go on.
-I'm… not used to the exercise...-

After a brief rest, the group finds opening C23 at ground level. Probably the biggest corridor in section C, C23 starts with a straight passage with an increasing ramp down, but not too steep nor narrow to cause discomfort in the claustrophobic Anya. In fact, the tunnel is big enough to allow even a scout titan to move around at ease.

Soon, the brightness of the extraction area is left behind and it's substituted by the faint shining of the sporadic mining lamps. Commissar Bryce and Thanatos take out some hand flashlights, but they don't turn them on yet.

Finally and after what seems like hours of wandering down the tunnel, the corridor abruptly ends into an underground mine vault. The wind howls indicating the huge size of the cavern in front of them. The weak light shows the start of another tunnel to the right and a metal stair heading down the abyss to the left. Far down into the pit of darkness, some screeching sounds can be heard here and there.

LIV finds a small cogitator on the wall next to the entrance of the tunnel.
-Commissar Bryce. The common geolocation of both objectives finish here..
-Ref 1- The right corridor heads towards the P1-10 compound`s source material location.
-Ref 2- The left stairs head to the missing troops location.
