Core-Worlds

Core worlds are simply the name given to quite a few of the colonies which form the 'center' from which humanity began colonizing the stars from. If Earth were to be considered the very center of it all, then those colonies which were generally nearest to Earth would be considered some of the core-worlds. Generally those colonies which are closer to Earth, the genesis of all humanity would be among the oldest and best established of the colonies, meaning that quite a large amount of the advanced materials and technologies tend to come from them. However, much of the drive for need of efficiency is gone, and while the core-worlds tend to preserve technologies, memories, history and quite a few other such important things they tend to be much less innovative in comparison to border-worlds.
