The Etran Harborage, also known as Trove as a loose translation of its original name, and formally designated as Shield World 0459,[3] was a Forerunner shield world located in the Korinth Prior system. A conservation sphere,[2] it was intended to protect sentient lifeforms from the effects of the Halo Array and the Flood. It also served as a military outpost housing the Apex Site, a port for a fleet of Sojourner-class dreadnoughts.[4]
Despite shield worlds being created as a haven from the Halos and the Flood, the external surface was heavily infested with Flood biomass, with forms of various types freely roaming across the surface. Sentinels were a rarity on the outside, but this changed within the center, where the many Forerunner constructs worked to prevent the Flood from claiming the interior as well.[5][6][7]
The Etran Harborage was discovered by the Covenant sometime prior to 2531. It was subsequently destroyed at the end of a battle in February of that year.[7] Though a debris field persisted until 2557, it was destroyed by a UNSC fleet following its discovery.[8]
Overview
This shield world's main structure consisted of the outer surface, the superstructure and tunnel system inside the crust, and the inner miniature Dyson sphere, along with its own miniaturized artificial sun to provide illumination. A series of latitudinal support ribs encircled the megastructure; these were clearly visible on the inner surface. The outer surface, as well as parts of the superstructure, were largely infested with Flood forms. Some of the Flood even reached the interior of the world through openings such as vents, but because of the larger numbers of Sentinels, never managed to fully infest it.
The ecosystems of the interior and the exterior were radically different, the outer surface being a rocky wasteland with large bodies of water and Flood biomass in some areas. The atmosphere was thick with dust, which may have been a defensive measure to disable starships and prevent them from carrying the Flood off-world.[9] Parts of the superstructure could be seen on the surface, with chasms reaching deep down into the interior.
The inner Dyson shell was completely terraformed and full of plant and animal life, much like the Halo installations or the Ark. It featured different types of Forerunner structures, ranging from spires to various walls or embankments and rifts leading into the interior of the structure. Like many other Forerunner installations, the Etran Harborage possessed a translocation grid in form of a network of teleporters.[5]
Access tunnels
The surface of the Etran Harborage had multiple access portals, which could be used to gain access to the interior of the planet. Most of them were likely hidden; for example, the portal through which the UNSC Spirit of Fire entered the interior was covered under a large body of water. The AI in control of these access portals would activate docking sequence when a ship passed over one, forcibly dragging the vessel inside by way of a series of field-projecting pylons on the outer surface.[10]
The tunnels inside the structure had a cleansing system which prevented the Flood from entering the interior. This quarantine system consisted of several "cleansing rings", which generated energy fields within their diameter, which would destroy any Flood biomass on a passing ship.[11] On the interior, these portals had six interlocks that needed to be opened in order to unlock the access to the tunnel, and like other significant systems on the installation, they could be operated only by a Reclaimer.[7] However, these interlocks only appeared to be triggered by the presence of the Flood nearby as the Covenant were able to enter and exit the interior shield world at will.
The Apex
- Main article: Apex Site
The Apex Site was an installation comprised of a control center on a platform high above the inner surface of the Etran Harborage, and numerous docking towers containing a fleet of Forerunner Sojourner-class dreadnoughts. The control center was accessible from the ground by a teleporter at the Apex Base Site, which was situated on top of a plateau with a series of ramps leading up to it.[6]
History
Construction
Etran Harborage was constructed during or prior to the Forerunner-Flood war to serve as both a military outpost to combat the Flood, and to preserve the lifeforms within from the Halo Array's pulse.
At some point, suspected to be relatively recently as of the 26th century, the installation became heavily overrun by Flood.[3]
Human-Covenant War
- "This world shall be the birthplace for an invasion fleet beyond imagining!"
- — Prophet of Regret
The Etran Harborage was discovered by the Covenant at some point before 2531, but then-current Covenant technology could not unlock its secrets. The Prophet of Regret sent Arbiter Ripa 'Moramee to the planet Harvest to investigate a Forerunner relic there that could have held the key.[12]
With the Human-Covenant War ongoing, the Covenant hoped to use the shield world's stored warships to crush the UNSC quickly, rather than wage the protracted war. However, they soon discovered that while they were able to access the installation, they were unable to reactivate the fleet.[13]
After the Covenant had observed Professor Ellen Anders activating the Forerunner relic on Harvest, the Prophet of Regret ordered the Arbiter to go to Arcadia and capture her, as she seemed to have valuable knowledge about the Forerunners. The Arbiter returned to Arcadia on February 10th, captured Anders and brought her to the shield world. Captain James Cutter, commanding officer of the UNSC Spirit of Fire, to which Anders had been assigned, ordered immediate pursuit out-system.[14]
- Main article: Battle of the Etran Harborage
Spirit of Fire arrived in orbit over the shield world, which appeared to be a normal, albeit desolate planet, on February 23rd. Ground forces were dispatched to the surface, where they discovered the Flood. Many of the reconnaissance teams were infected and it was discovered that Anders' transponder signal was being duplicated by a Proto-Gravemind; eventually, the Proto-Gravemind was killed in a concerted attack.[15] A few hours later, the Spirit's shipboard AI Serina scanned the planet for the professor's signal, which seemed to be originating from an ocean; the ship was suddenly pulled into the shield world's internal docking mechanism. After passing the tunnels inside the installation's superstructure, the Spirit of Fire emerged within the internal Dyson sphere.
Some time later, the Arbiter used Anders, who had been kept prisoner at the Apex Site, to activate the fleet of Forerunner ships. However, as the awestruck Sangheili watched the fleet's activation, Anders managed to escape via the installation's teleportation grid and regroup with the other humans.[5] She then created a plan to prevent the Covenant from using the Forerunner fleet which involved transporting the reactor of the Spirit of Fire's Shaw-Fujikawa Translight Engine to the Apex Site and from there into Etran Harborage's artificial sun.[6] Once the Spirit of Fire opened the door interlocks blocking the Spirit of Fire from exiting the shield world, Sergeant John Forge detonated the reactor inside the sun, causing it to go supernova. The supernova obliterated the Dyson sphere and caused the outer planet to blow up in an immense explosion that left a massive debris cloud.
The destruction of Etran Harborage destroyed the Flood and Covenant forces on the planet as well as the Forerunner fleet, depriving the Covenant of their planned advantage over the humans using the ships. However, using their Slipspace drive to destroy the planet resulted in the Spirit of Fire being stranded far from human space with no way home.[7]
Remnants
After hijacking the UNSC Rubicon in 2554, 343 Guilty Spark intended to take the ship to the Etran Harborage to get an upgrade seed to better prepare the ship for his planned mission to find the Librarian. However, the ship was destroyed before he could complete the journey and as Spark had been unable to connect with the ancilla of the shield world for some time, he was unaware that the planet had been destroyed.[16]
The debris field that was left by the Etran Harborage's destruction was eventually rediscovered by the Ace of Spades in 2557 with the ship's captain, Rion Forge, searching for the UNSC Spirit of Fire and her missing father John Forge. The ship was able to recover Little Bit, a fragment of the shield world's AI and learn of what had happened.[17] The crew was later forced to turn over what it had learned to ONI along with Little Bit.[18]
- Main article: Mission to the Korinth Prior system
Using the data from the Ace of Spades and Little Bit, the prowler UNSC Taurokado embarked upon a mission to the debris field where it encountered a Covenant battlegroup led by Gek 'Lhar. The Taurokado retreated from the system following the encounter while the Covenant forces began harvesting the remnants for their own usage.
At the same time, to complete his mission, 343 Guilty Spark brought the Ace of Spades back to the Etran Harborage to get an upgrade seed for the ship, unaware that the planet had been destroyed. As further incentive for the crew to help him, Spark offered access to the wealth of Forerunner technology within as much needed salvage. As the salvage ship struggled to evade the Covenant, a massive UNSC fleet emerged from slipspace and opened fire on the debris field with nuclear weapons to deny its assets to the Covenant. The nuclear weapons would blow the debris to bits and disrupt its gravity around the system's dwarf star. Whatever survived would likely be pulled into the star itself, completely eradicating the shield world. The Covenant fleet retreated into slipspace to avoid being destroyed while Spark managed to get the Ace of Spades into slipspace in time to avoid destruction as well.[8]

Trivia
While in the pre-rendered cinematics the lines on the inner surface of the shield world are latitudinal, they are longitudinal in-game in the level Repairs. The appearance of the surface is also different, which is likely due to the disparity between the in-game graphics engine and the pre-rendered cutscenes.
