Kessra Deep

Kessra-9 needs miners. Halberd Extraction pays for everything you bring up.

You are Contractor no. 7. Your pod has a drill, a small fuel tank and a hull that does not like falling. Dig into the moon, haul ore to the surface, sell it at the refinery and spend the money on a better drill, a bigger tank and a hull that can take the heat. Then go deeper.

Your supervisor, Vell, is always on the radio with tips, jokes and a few words about every new mineral you find. She is very encouraging. She would really like you to reach the core.

Six contractors went down before you. None of them came back.
