- "What happened was, you had drifted right through the Core Systems, and it's really just blind luck that a deep salvage team found you when they did. It's one in a thousand, really."
- ―Carter Burke to Ellen Ripley (from Aliens)
The Core Systems covered a central region of space bordering the Outer Veil. The region contained the New Eden Sector and Sol Sector, and was a major territory of the Independent Core System Colonies and the Three World Empire.
