Core Worlds (Earth-2356)

The Core Worlds, also known as the Coruscant Core, the Core systems, or simply the Core, is the area of the galaxy that borders the Deep Core and contain some of the wealthiest and most prestigious planets. Coruscant, the galactic capital during the time of the Galactic Republic and subsequent Galactic Empire, is located in the Core Worlds.

Citizens from the Core Worlds are stereotyped as being snobs, rich, and speaking with a clipped, practiced accent.

Core World design emphasize freedom of customization, which is shown in the modular construction techniques of Core-built ships.
