A fully operational map of the universe that updates itself on current astronomical data by a highly advanced algorithm. This map is the total territory in which the Precursors have explored. The mapping system is housed in a gigantic ship which the species of the Milky Way have come to call it “The Cartographer”.
An Order member while on a mission on Versuvian managed to collect a scan of the mapping system and the ship itself before PRAXIS’ armada attacked. The ship at the time was buried underground, but has since been recovered and has been seen being commanded by Mareth.
