The relay network is composed of clusters and superclusters.

Clusters: Clusters are small areas of space connected within a super cluster by secondary relays, while some clusters contain primary relays connecting to other superclusters. Clusters are commonly dozens or even hundreds of light-years away from each other.

Superclusters: Superclusters are large areas composed of 1 to 8 clusters and are connected to other superclusters by primary relays. Super clusters are thousands or tens of thousands of light-years away from the nearest supercluster. Without the primary relays it could take decades for civilizations to reach one supercluster from another.

Orion vault supercluster: The Orion vault is The home supercluster of humanity and where they are most concentrated. The systems alliance has created legislation strictly controlling colonization in the Orion vault to ensure no situations arise that may threaten humanity and its major colonies.

Clusters: local cluster, arcturus stream,Garden of Eden (centered around the first 100% confirmed habitable planet discovered in 2053 by space telescope), Corona australis (Location of closest neutron star), Pleiades cluster.

Primary relay connections: Orion frontier, Olympus/kraskradiv (" Masters palace" disputed name between systems alliance and batairan hegemony)

Orion frontier supercluster: The Orion frontier superclusters is one of the two super clusters connected to the Orion vault by the relays in arcturus. It was the first Super cluster explored and colonized outside of the Orion vault by humans and is one of the most populated. It resides at the edge of the Orion arm and crosses over into neighboring arms and the void in between. It is sometimes considered part of Council space. Commonly considered the more civilized arm of human expansion for its significant lack of slavery and piracy compared to territories closer to the hegemony and the terminus systems.

Clusters: Exodus cluster, Horse-head nebula, forsaken cluster, travelers rest(both previous clusters sit between galactic arms),valsoreae ("people's home" Home cluster for the valsor protectorate under the systems alliance)Xìngyùn cluster,

Primary relay connections: Orion vault (human home supercluster),proverdexae (recovered prothean name translated to "Heart of the empire"),zalvetris (turian colonized supercluster translated to "outer dominion" [Has direct connection to avaetris "Home dominion" Origin cluster of the turians])

Olympus Supercluster/kraskradiv: The Olympus relay was opened three years before the beginning of the first contact war, it is commonly speculated by historians about how first contact would've happened if it occurred in Olympus as the primary species in this territory besides humanity is the batairan hegemony. The super cluster is heavily patrolled by both sides but neither attack their own sponsored privateers or slavers. The only reason both sides haven't gone to war is the crippling economic damage that would be caused by the disruption in movement through the jointly controlled (and unguarded because of dispute and both sides wanting their privateers and slavers to be able to enter the verge without interception) Skyllian alpha and beta relays.

Clusters: Argos rho, hades gamma, Gemini sigma, Artemis tau, Voyager cluster, attican beta,varkrivolk ("conquerors triumphs" Home to 2 hegemony slave species),

Primary relay connections: Orion vault, Skyllian Verge beta, zakavasher ("higher homeland" batairan home supercluster),Skyllian Verge alpha.

Skyllian Verge beta Supercluster: The verge beta is a constant battle ground with no end in sight. Due to treaties between The Systems Alliance,Narn Regime and the Hegemony all sides can only send minimum amount of military ships Into the verge. This situation has led to all sides deploying privateers to protect their assets and attack the opposing side's assets while the hegemony also deploys slavers to capture humans and narn. The territory is a nightmare that has not had a positive birth-death ratio In 20 years and has only grown in population because of immigration to exploit the plentiful resources of the verge.

Clusters: Armstrong nebula,Kepler verge, maroon sea, shadow sea, The divide, Crimson sea (center of narn colonization in the Supercluster)

Primary relay connections:Olympus/kraskradiv, greater Attican,saldovorgres ("Virgin wasteland" asari name for a Territory mostly destroyed by the rachni in their initial onslaught and now controlled by the terminus systems)

Skyllian Verge alpha Supercluster:. The territory is significantly safer than the verge beta due to significant upper caste Hegemony population making escalation in the area unpalatable to the hegemony . This allows all partys to exploit the plentiful resources of the verge with less fear of death until this blitz where the hegemony used the alpha relay to bring in pirates and slavers from aztrovlekov ("freedom's temple" One of the core super clusters of the terminus)

Clusters: viper nebula,Petra nebula, Longbow nebula,

primary relay connections:Olympus Supercluster/kraskradiv,

zakavasher: The core of the hegemony, zakavasher is home to over 45 billion out of the 64 billion hegemony citizens of witch 20 billion are slaves and most of the rest are of the lower castes. Out of the population under 1 billion are of the top three casts Who control over 95% of the wealth. The super cluster is home to over 2/3 of the hegemony military meant to protect the High cast citizens from any harm.

Clusters:kite's nest, Babylon's tragedy (Home to the first hegemony slave race[hello minbari ), demon's sanctum.

Primary relay connections:Olympus/kraskradiv (Calling the Supercluster Olympus is punishable by death in the hegemony),proverdexae,saldovorgres

proverdexae: Home to the citadel, if Thessia is the heart of galactic civilization then proverdexae is the vains. Circling the citadel are the most amount of mass relays in a single spot in the known galaxy. The citadel and its home supercluster is the core of galactic civilization and every species with over a dozen planets recognizes the council who controls the citadel as the masters of the Galaxy.

Clusters: serpent nebula

primary relay connections:saldovorgres, Orion frontier,zakavasher,athaldoras (Asari and elcor home supercluster),soorkelltis ("Hidden sanctum" salarian home super cluster)ireltise (volus Home supercluster), Perseus edge (quarians home supercluster now mostly controlled by the geth), Kogan demilitarized sphere (krogan home supercluster)

Author notes: these are all the Superclusters that I am currently listing. also there is an alteration to the timeline, cruiser groups consist of one light carrier , three cruisers, and eight escorts now.
