Archimedes' mirror

Exploration Stage: City Hall
From: Helen
Description: Next is the all-important reflector. It is needed to see the sky without being disturbed by fog. The collector's projector will be ready soon. Then we will be able to look up at the starry sky for the first time in years! I can't wait! Now, let's find the faceted mirror.
Completed: Yes, this is a faceted mirror made from a collector's blueprints. Perhaps it was he himself who made it. But he did not invent it. Archimedes used such a mirror long ago. It is said that he used it to set fire to the Roman fleet during the siege of Shrakusai.
