Codex Information



Nexus: Pathfinder HQ

The Pathfinder Headquarters on the Nexus is designed to record and celebrate the achievements of the Initiative's Pathfinders, while also providing a space for them to relax and regroup when off duty. The Pathfinder HQ is not normally open to the general populace, but Director Tann has permitted guided tours since Ark Hyperion's rendezvous with the Nexus.

The Pathfinder HQ preserves mission-significant items, mineral samples, and planetary surveys. If and when the initial settlement phase is complete, the Pathfinder HQ will contain a historical record of the Pathfinders' efforts to colonize Heleus. Meanwhile, Director Tann has established his offices here, as part of his duties in overseeing Pathfinder operations.

Nexus: Hydroponics

The Nexus's original encounter with the Scourge caused heavy damage to the station. Reports show that Hydroponics suffered the brunt of the damage, deepenning the resource crisis. In response, Dr. Eliot Camden, the new head of Hydroponics, requested that planets be distributed throughout the station to prevent similar losses.

According to station resource allocation, Hydroponics currently accounts for 38% of the Nexus' water ice consumption. After undergoing reverse osmosis to remove heavy metals, the water is divided into reservoirs for each plant variety and a macronutrient mix is added. VI systems constantly monitor the pH, temperature and dissolved solids count of these reservoirs.

The flora in Hydroponics was chosen by crop varieties and oxygen yield. While most of the Nexus' oxygen comes from electrolysis, its plants improve overall air quality. Psychological reports also show a marked improvement in station morale since Hydroponics' recovery.

Nexus: Culture Exchange The Culture Exchange was created to support the Andromeda Initiative's princples of peaceful exploration in the new galaxy. Given the high likehood of contacting sentient alien life in Andromeda, the Exchange was designed to educate and inform local species about the history and intentions of the Milky Way settlers. The hope was to avoid any misunderstandings which could lead to suspicion or hostilities, and instead foster an air of cooperation beneficial to all.
Nexus: Leadership

As the base of operations for the Andromeda Initiative, the Nexus leadership was always intended to be split between the Initiative proper, station operations, and colonial administration. Jien Garson planned to retain an honorary role, electing the asari Matriarch Nuara as Initiative Director.

Unfortunately, both Garson and Matriarch Nuara are listed as deceased, along with many of Nuara's senior staff. The current director of the Initiative, Jarun Tann, was eigth in line of succession.

Today, Director Tann remains officially in charge of Initiative operations and Pathfinder teams. Foster Addison retains her post as director of Colonial Affairs, managing colonist and outpost deployments. The Nexus itself is administered by Superintendent Nakmor Kesh, who also oversees construction efforts.

In the wake of the kett attacks, Tiran Kandros emerged as leader of a de facto volunteer militia that has taken over station security. Though technically a civilian, Kandros is counted amongst the Nexus leadership.

Andromeda Wildlife: Overview

The nature of life in Andromeda Galaxy was debated at length by Milky Way scholars. Milky Way species show convergent evolution-upright bipeds of a certain height and atmosphereric tolerances-leading some to theorize this pattern might give some evolutionary advantage, despite counterarguments by hanar scientists. Interestinly, the kett and angara continue to fit this pattern.

The wildlife and flora encountered in th Heleus Cluster have adapted to the presence of the Scourge, evolving epidermal layers or carapaces that can cope with ambient radiation, or in the case of some plants, successfully feeding off it. Many use bioluminescence to attract prey, or as a threat ot mating display.

Concerns were raised around the ability of Milky Way species to consume porteins from Andromeda, so seed banks formed a significant part of the arks' cargo. We now know it is safe to consume food grown or hunted here, though enzyme supplements are recommended and have become a social norm at mealtimes.

Remnant: Interfacing 

Remnant technology requires careful reactivation dubbed "interfacing" a process Alec Ryder and I first developed on Habitat 7. Using "gylphs"-dense data packets of remnant code-a working understanding of their language, and the interface capabilities of a Pathfinder implant, I can help you trigger or control Remnant technology from appropriate locations.

Interfacing is the only way to activate certain Remant technology, such as monoliths. Scan and surface damage suggest that the kett have repeatedly attempted to activate these sits by other, increasingly desperate methods, without success.

It is not clear whether Remnant technology is designed to be activated by an AI. There is no evidence of artificial intelligence in the Remnant structures investigated thus far, and Remnant bots have only rudimentary programmning. However the gylphs contain recognition keys analogous to an electroencephalogram (EEG), implying that the system is designed to handle a form of neural input.

Remnant: Creators

An artificial creation must have a creator, but there is scant evidence of whomever created the Remnant. I have consulted the Nexus scientists, scans obtained by Peebee - on the condition that I not rearrange her data - and records of your own investigation, but my conclusions remain speculation.

We can be certain that the Remnant builders are several orders of sophistication above the Initiative's technology. Interlinked cluster - wide planetary engineering is beyond the logistics or budget of any known species. The energy requirements alone suggest a Type I civilization on the Kardeshev scale.

On a cultural level, the builders must have been intelligent and capable of large-scale cooperation. The proportions of the values and devices found suggest a species with similar physical traits to humans, but with no genetic evidence left behind, their appearance - along with their motivations - remain a mystery.

Remnant: Decryption

Most Remnant technology is inert or in a "standby" mode, but some is secured with a decryption grid. Unlocking it requires scanning the correct Remnant glyphs and arranging them in a specific order. The glyphs cannot repeat on any straight line or within a square block of four.

Peebee speculats this could be a safety measure. Even if a method was devised to brute-force hack an interface, it would not work with the decrytion grid. Given the devastating consequences when Remnant technology is improperly activated, her analysis seems sound.

The arrangement of the glyphs appears to complete either a password or a code phrase within the grid as a whole. From the little I understand of the Remnant language, they appear to form an almost palindromic "Sator Square" sentence, but the finer meaning would require detailed explanation from the grid's designer.
