Remnant machines

The Remnant are a synthetic race encountered by the Andromeda Initiative in the Andromeda galaxy. "Remnant" is an umbrella term that refers to the autonomous machines, the structures they're commonly found guarding, and the underlying technology common to their construction. The Heleus Cluster is dotted with Remnant sites and technology, most of which are inactive and yet to fulfill the purpose set by their equally mysterious creators.

Design[edit | edit source]

Most of the known Remnant ground units are named by Pelessaria B'Sayle according to their observed behavior and colored by her personal quirks. The term "Remnant" itself comes from her belief that the synthetics are remnants of something much bigger, only shortened to her liking.

The Remnant machines come in many forms, none of which are humanoid but nonetheless suited for their intended function. They are typically bulky machines, with the smallest the size of a large pet and the basic units about the size of a small human.

Most of the walkers feature jumpjets on their legs that allow them to traverse elevated terrain. The floaters typically have element zero cores to help them levitate. The bots "bleed" a glowing bluish fluid when shot. On standby, their circuitry patterns glow blue and some may even emit scanning fields from time to time. On detecting non-Remnant, their circuitry patterns turn red and they become hostile until the target is dead or out of range.

The bots only have rudimentary programming and are not sapient. However, some units do employ lossless memory partitioning tricks that may be of use to future artificial intelligence designs.

Subtypes[edit | edit source]

Remnant units include:

  • Abyssal - massive wormlike construct inhabiting the deserts of Elaaden.
  • Architect - massive floating wormlike construct that turns hostile when activated.
  • Assembler - basic Remnant unit that can manufacture Breachers.
  • Breacher - floating unit used for immobilizing targets or as a suicide bomb.
  • Creeper - maintenance drone typically found around desolate Remnant sites.
  • Destroyer - heavy weapons platform guarding important Remnant installations.
  • Nullifier - long-range artillery unit that can deploy a barrier to protect itself while it forces targets out of cover.
  • Observer - basic floating unit employed as a maintenance drone but also armed with a continuous laser.
  • Progenitor - more powerful Destroyer variant that can also manufacture Observers.
  • Turret - static defense around certain Remnant sites.

History[edit | edit source]

The Remnant were created by an advanced species possibly native to the Heleus Cluster known as the Jardaan. After some sort of conflict that unleashed the Scourge in Heleus, the Jardaan left the cluster and have not returned since.

Remnant structures found on Habitat 7 have been dated to 300-400 years old, meaning they were constructed during the Initiative's journey to the Heleus Cluster. Carbon dating on the vault structure at Eos indicates the vault went dormant at about a similar time period.

While investigating the vault on Eos, Pathfinder Ryder theorized that the Remnant may have been attempting to terraform the Heleus Cluster. The theory was proven correct when after the vault's activation, irradiated Eos quickly became tolerable for human settlement. Vaults in other worlds can similarly be reactivated by the Pathfinder, improving their colonization viability.

The Archon, leader of the kett force invading the cluster, developed an obsession with the tech believing it would grant him uncontested power over his peers, and thus took over numerous Remnant sites and artifacts for study at the cost of stalling the actual invasion. He has located "Meridian", a place he believed to be key to mastering the Remnant.

Further discoveries reveal it was only the command core for the actual Meridian. Through exploiting Ryder's sibling's connection to SAM, the Archon found and almost managed to subvert Meridian to his will, although the Pathfinder team dealt with him shortly and used Meridian to resume terraforming the entire cluster.

While the origins and general purpose of the Remnant were made clear by the time of the Archon's defeat, several facets of their behavior remained unexplained to Initiative scientists, such as several ships docking with Meridian then going off to destroy themselves at the Scourge.

Culture[edit | edit source]

As the bots themselves are not sapient, they have no culture to speak of other than following their programmed directives.

Technology[edit | edit source]

According to Foster Addison, Remnant technology is actually less advanced than the Prothean technology uncovered on Mars. The main difference between the two is that while Prothean technology is "plug and go", Remnant technology "thinks differently".

Most Remnant technology is found in a "standby" state, requiring an interfacing element composed of an organic mind and an artificial intelligence to activate. Some of the native angara have a natural ability to interface with Remnant tech, although without an AI their skill is severely limited and may require a lifetime of practice for even the simplest commands.

A defining look of Remnant technology is glowing green circuitboard patterns amid angular metallic exteriors, even in places where there are no obvious sources of power.

The massive Remnant structures on many worlds appear to be terraforming mechanisms with planet-wide effect capability. As deciphered glyphs found within the Eos vault shows, terms such as "atmospheric control" show up. Initiative scientists believe that, if it works as intended, it can modify almost all aspects of a planet. As evidence, after the Pathfinder team "rebooted" the main controls in Eos, the storm that plagued the initial settlement efforts was gone, allowing for the third try to become successful.

The Scourge is aggressively attracted to Remnant tech, and actually caused the initial shutdown of all terraforming efforts within the cluster.

Language[edit | edit source]

Thus far there's no spoken language found with the Remnant, only indecipherable machine beeps and a "written" language in the form of glyphs. Such glyphs contain immense amounts of information encoded in a single symbol. Collection of the glyphs in the field plus other research materials recovered by the Pathfinder team allows SAM to provide partial translations if and when needed.

Some Remnant tech are secured with a decryption grid. Unlocking them requires scanning the correct Remnant glyphs and arranging them in a specific order. Remnant Decryption Keys are items that can be used to bypass some of the decryption grids.

Military[edit | edit source]

Remnant ground forces are mostly maintenance drones that can double as intruder repellants whenever the need arises, although they still have dedicated weapons platforms such as the Destroyer. The basic units are deployed en masse and treated as expendable.

The Remnant also field starships ranging from personal fighter-sized vessels to gargantuan structures comparable to dreadnoughts. The smaller craft have a sleek design while the larger vessels look like inverted pyramids.

Remnant bots mostly rely on in-built weapons, although one component that can freeze enemies can be adapted by an omni-tool into the Remnant Cryo-Gauntlet.
