Star map

From Halopedia, the Halo wiki

A star map of the Epsilon Eridani system on a holotable onboard UNSC Spirit of Fire.

A star map is a holographic map displaying various locations in and beyond a galaxy.[1] It is typically used for astrogation.[2] The Forerunner employed a similar technology known as star charts;[3] various Forerunner technologies, like the Luminary and the Janus Key, use star maps to indicate key locations.[4][5] The Covenant reverse-engineered the Forerunner star maps to develop their equivalent[6]—interactive holographic star maps known as a kelguid.[7]

Operational history[edit]

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 UNSC Spirit of Fire to Arcadia.[8][9]

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.[10]

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.[11]

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 UNSC Pillar of Autumn 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 Bactrian-class freighter approaching the Halo fragment.[12]

In February 2558, Fireteam Crimson encountered a star map at "the Refuge" on Requiem and helped Jared Miller download the data.[1] Combined with earlier intel on Covenant archeological teams, it led to the slipspace artifact located at "the Cauldron."[13]

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[14] where the third piece of the key was located.[15]

Non-canon or dubious canon appearances[edit]

Silver Timeline[edit]

Main article: Silver Timeline

After Makee activated the Forerunner Keystones together, they began displaying a star map leading to Halo ring. However, after Makee was apparently killed by Kai-125, the star map disappeared before it was complete.[16]

Cortana later attempted to help Makee pinpoint the location of Halo on a star map, suggesting that they could use the stars in Halo's sky from John and Makee's shared vision to find it. While reporting to Admiral Margaret Parangosky, Cortana revealed the location of the Covenant fleet on a star map.[17]
