2. Great Traction Cities

The undisputed apex predators of the Great Hunting Ground. Their reliance on Municipal Darwinism trapped them in a thermodynamic paradox: the caloric energy required to mobilize such immense tonnage ultimately exceeded the yield of their prey, dooming these apex urbivores to eventual starvation.

7. Architectural Ghosts: The Lost Cities of the Ancients

To comprehend Municipal Darwinism is to study the crystallized ruins upon which it rolled. The Ancients built towering, static marvels that were ultimately vaporized during the Sixty Minute War.
