Yihelli Quadrant is a region.


Yihelli Quadrant is a region in the Euclid galaxy of No Man's Sky.

The region is estimated to be 3.7 billion years old.

It is a tree shaped region located within approximately 8,000ly of the Galactic Hub Project. It was discovered by AGT Traveller zazariins/zazariins during the final months of the Atlas Rises era and is the result of an agreement between the Galactic Hub and the Alliance of Galactic Travellers, whereby both civilisations agreed to co-locate to within a 20,000ly radius of each other within the Gamma Quadrant. This was designed to further aid collaboration and diplomatic relations between the AGT and the Galactic Hub and was effective from the beginning of the NEXT era.

It is observed to contain 513 normal star systems. Phantom stars start at solar system hex code 202.

Note: Pre-Expedition pages that have an updated Expeditions or later page for the same systems/planet/moon etc are NOT counted in the pre-Expedition columns.

Discovered systems[]

The region is estimated to be 99% discovered.

Documented Systems[]

Note: Approximately 30% of the systems names listed in the wiki for this region may be obsolete now due to the post-Expeditions universe name discovery consolidation. These system names were documented using the PC names pre-Expeditions, however surveys indicates most PS4 discovery names are used due to their slightly earlier discovery dates. The AGT is working to correct the records but it may take considerable time. We anticipate completing the updated records for all 513 non-phantom systems by Sep 2021.

Neighbouring Regions[]

Civilized Space[]

This region is home to the Alliance of Galactic Travellers and serves as their capital region for the Euclid galaxy.

Defined by the presence of a permanently occupied base build, the region is currently home to a large number of AGT travellers. About 50 are based in AGT Nexus, but others are scattered across the region.

A number of other civilizations have sent ambassadors and established embassies within the Yihelli Quadrant. These are counted within the region's occupancy count - but are not counted within the overall census for the Alliance of Galactic Travellers unless specifically agreed with the individual.

Additional Information[]

  • Zazariins is the first known explorer to document in this region.
