Locator logo insignia showing the galaxy's Beta Quadrant.
The Levintine Expanse was an area of Federation space in the galaxy's Beta Quadrant, where the planet Rigel XII was located. (SA video game: Starfleet Academy; SA novelization: Starfleet Academy)
- Presumably this expanse would include the entire Rigel system, however, only the twelfth planet was specifically mentioned as being located there.
