Evidence in the Aya vault shows the network of Remnant vaults across the Heleus Cluster is controlled from a central point known as "Meridian". When properly Connected to Meridian, the vaults function as designed, terraforming and maintaining planetary conditions to make planets suitable for life. When disconnected, the vaults appear to either go into standby-as seen on Eos or malfunction as may have happened on Habitat 7 with disastrous consequences for their planet.
This proves Meridian's Central importance to Remnant vaults and the planets of the Heleus Cluster. Whoever Controls it can theoretically affect vault function, meaning they could control-or disrupt-the ecology of entire Worlds.
