Star map

A star map is a map displaying various locations in and beyond a galaxy.

Operational history
On February 4, 2531, Professor Ellen Anders activated the Relic which displayed a map of nearby star systems. This star map led both the Covenant and the to Arcadia.

On November 3, 2552, following the aborted firing of Installation 05, the display in the Control Room showed a star map depicting the various locations of the Halo Array as 343 Guilty Spark explained that the Array was now in standby mode to be activated at the Ark.

On December 11, 2552, Spark accessed a star map through the Ark's Cartographer which revealed, much to his surprise, that the Ark was actually located in intergalactic space.

In February 2556, Alistair Estrin used a star map to show what had been discovered from the tug that had transported the mystery element to Sedra that was used in a terrorist attack, revealing that it had been sourced from a fragment of Installation 04. After Private First Class Talitha Macer theorized that the element was created by the supernova-level explosion of the that destroyed the ring, Commander Jameson Locke had the star map perform a scan and locate the element and then scan the rest of the known universe for it, coming up with no results. However, the star map detected another approaching the Halo fragment.

In August 2558, the crew of the Ace of Spades visited Installation 07 where Spark used the Librarian's coordinate key on the Halo ring's Cartographer. After Rion Forge added her touch as a Reclaimer, the Cartographer displayed a star map leading to a specific location on New Carthage where the third piece of the key was located.
