Mass Relays |

| Type: Primary |
| Installation: Base Installation |
Mass relays are feats of Prothean engineering advanced far beyond the technology of any living species. They are enormous structures scattered throughout the stars, and can create corridors of virtually mass-free space allowing instantaneous transit between location separated by years or even centuries of travel using conventional FTL drives.
Primary mass relays can propel ships thousands of light years, often from one spiral arm of the galaxy to another. However, they have fixed one-to-one connections: a primary relay connects to one other primary relay, and nowhere else. Secondary relays can only propel ships a few hundred light years, however they are omnidirectional: a secondary relay can send a ship to any other relay within its limited range.
There are many dormant primary relays whose corresponding twins have not year been located. These are left inactive until their partner is charted, as established civilizations are unwilling to blindly open a passage that might connect them to a hostile species. |
