The FOUR CORE WORLDS are the planets Aphrophine (Your Agency), Dakka (Your Agency), Borauris Ester (Blue Agency), Conus (Coral Agency), and their moons.
The Core Worlds were colonized during the late Expansion Period and their locations, resources, and development potential were a source of ongoing conflict that continued into the War Period. Each Agency established early, large-scale colonies on these worlds and later expansion and development tended to proceed from these points. The most famous of these conflicts were the First and Second Aphrophine Wars, fought between Your Agency and Blue Agency over control of the golden-green planet Aphrophine. Large areas of Aphrophine were devastated, and made virtually uninhabitable, during these two conflicts. The worlds are traditionally thought of as being the physical meeting point of all the Three Agencies and as a result have often been used – with various degrees of success – as symbols of unity between the Agencies.
The term “Core Worlds” is regularly conflated with “Home Worlds” in common parlance. “Home Worlds” is a Fencepost Period term referring specifically to star Sol and the bodies orbiting it.
