The Neptunian world Harvey
The Aristotle system was colonised in 691 AT. This system contains Darwin, the closest Garden World to Sol. After the Battle of Darwin, this life-bearing world has been off-limits for colonisation, and only scientific expeditions may land there.

Mendel, a Mars-like world which has been terraformed and is now one of the main centres of population in this system
The Arean world Mendel has since been terraformed, and is now one of the main centres of population in this system. Part of the biosphere of Mendel is derived from Darwinian templates.

Empedocles and Pliny

The relatively new McKendree cylinder known as Empedocles is eight thousand kilometres long, while the older cylinder known as Pliny is only five thousand km in length.
Other major centres of population include the McKendree Cylinders Empedocles and Pliny, and the Origen Band of habitats around Darwin.
