(General POV)
Location the Mass Effect World-Planet: Rannoch, Surface
Rannoch an arid planet, hot and highly cayon, and rocky like landscape, this world...once used to be the homeworld of the Quarians.
Quarians, are now a nomadic species of humanoid aliens, with three-digit xenos with purplish skin color, Quarians are known for their skills with technology and synthetic intelligence, but since their homeworld Rannoch was conquered, by their own "supposed" cybernetic race of the Geth.
But the most distinct feature of the Quarians is their biology.
Which is very weak, a sensitive immune system, the result of being centuries of living in sterile environments, the side-effect of losing their homeworld to their hated enemy, the Geth.
As a result, all Quarians by necessity dress in highly sophisticated enviro-suits, to protect them from disease or infection if they are injured, their suits can be compartmentalized in the event of a tear or similar breach to prevent the spread of contaminants.
Along with their suits, quarians also have extensive cybernetic augmentations integrated into their bodies, a Quarian's lifespan is roughly equal to a human's, but is prone to be less if infection breaks into the suit.
As for the Geth, they not only rule over the planet of Rannoch, raiding the stars, having a hatred or great disdain towards the organics, leading the Geth to be a highly hostile race in the wide, vast space, on a Quarian facility with a wide open balcony like entrance, several Geth armed with various firearms, were standing guard, having a unique appearance, as their physically design, of the Geth, is humanoid.
Geth resemble their former creators and slavers the Quarians, their hands, head shape and legs are similar, which is probably a holdover from their origins, all Geth having a common design feature among Geth is a single brightly glowing photoreceptor, causing some to refer to them as "flashlight heads", by other races.
Geths' have a unique form of sentience and intelligence, which is dependent on being in groups, in close proximity to each other, due to their neural network. They effectively, "share" their processing power, spreading data, and analyzing capacity on some level of complex thought, and eliminating the need of wasting time and decoding on non-important subject, thus freeing up bandwidth for higher reasoning and complex thought.
Geth can't share sensory data, they aren't a hive mind like the rachni, but in large groups they have more to think with, an individual Geth has only a basic intelligence on par with animal instincts, but in groups they can reason, complex thought, and think in some level of detail.
Hence once one Geth is spotted in any world, there are more likely hundreds more, raiding and collecting technology to integrate and evolve their race, as a whole, eliminating all threats, especially their mortal enemy the Quarians.
Currently, the Geth were in high-alert, some time ago, their enemy have managed to hack into their neural network, and steal important data, specifically the priority locations of Geth factory and strongholds in Rannoch.
Hence a signal was sent out...or soo the Geth, believe that it was a signal by their kind...
That signal was recalling every single Geth, in the galaxy sector, back to Rannoch, as a unknown signal, but carrying the monikors and correct codes, the Geth didn't questioned it.
Truly believing this signal, is a SOS caller them back, ready for war, as not only is the Quarian Fleet, finally making it's way back to Rannoch, their world, but bringing with them the infamous Shepard of the Normandy.
Responsible for not only eliminating, many of their kind, but also the rachni and the sole being to have defied the Reapers...their Gods, when the Geth witnessed their power and divine majesty, many believed that their origins are lies, that the Reapers are their creators not the Quarians.
In fact many worlds, that have a deep connection to the Reapers, has Geth influence and forces swarming the surface, but this sensitive manner of their homeworld being under threat, this has sparked aggression and worry in the millions of Geth.
Now under high alert, awaiting their enemies to make planetfall and face them, while these Geth are watching over the main entrance of this facility, multiple levels below, several Geth were working with extreme fervor.
Using their installe Omnitools, to manifest a yellowish holographic gauntlet around many of the Geths' arms, others were typing at the console, resembling a giant pillar with cables, pertruding and connected to the rest of the facility.
These Geth, they're desperately trying to disipher what this transmission signal is, they've notice that as more and more Geth, were landing on Rannoch the signal became stronger and more pronounced.
Now instead of just calling back the Geth, it was actually trying to hack into the main neural network, this was a grave situation, as the Geth were trying to crack what this system intrusion really is, all the while code and symbols of unknown origins, wasn't only spreading through the Geth network, but also another more ancient one, as well.
Location Deep Space, Nameless Sector
Through the galaxy of stars, with shades of blue, cyan, and aqua forming a swirling, still whirlpool filled with countless shining stars, and a couple of planets, three to be exact, surrounding a young Blue Sun, at it's center.
Within this nameless sector, their was also three titanic machine, like entities devastating these worlds, harvesting and destroying all life off these worlds.
These machines that highly resemble a cuttlefish or squid or even a micro-breed of crustacean, with dark metallic coat, with shades of grayish-purple, and dark purple mixed with the black under-coat.
A form that has all have a tapering plate over the rear and five or six tentacle-like "legs" or arms extending from its front end, in addition to six jointed legs extending from its body, highly mechanically "face", compose of multiple lights of red.
These are the Reapers, finally starting to purge and harvest all life from the Solar Galaxy, as two of these Reapers have superficial resemblance to a, with a bulky semi-cylindrical body, but the largest of these trio of reapers, is Sovereign.
Having finished the harvest of jungle world, it started to leave the planet surface, and navigate Space, when something infiltrated its system, causing the reaper to twitch, spasm, and glitch, as unnatural amount of data, energy, and power was forcibly, cycling Sovereign's main system and form.
Severing its connection to the main fleet, and mind of Harbinger, no matter what Sovereign attempted this unknown infiltration, preceed anything that the Reapers have encountered, then a name entered Sovereign's mind, "VASHTORR"
Location the Immaterium: Forge of Souls, the Throne of the Original Heretek-z
Suddenly as all Sovereign sensors, started functioning the reaper realized it was no longer in the harvested galaxy, it and two other Reapers have just purged.
Scanning the area, all its optic systems can perceive is someking, colossal forge, drastically massive, easily accommodate the fleet of Reapers, which is utterly impossible to build something of this mass, and empower it without the Reapers discovering it.
As movement caught the reaper's scanners, resembling Earthling skulls merged to mechadentrites, modeled like arachnids, then another creature appeared, another type of arachnid made of flesh and machine, tentacles, claws, and maws hissing and roaring at Sovereign.
But that wasn't the end, other techno-organic creatures started to emerge, from spheres, chrome skeletons, and more.
For the first time in eons, Sovereign felt...felt something...inferiority and intimidation.
Eons of ending worlds, with little if not complete effectiveness, but all its power, advance weaponries, as well as nearly unrivaled capabilities, all seems utterly inferior and worthless against these creatures, all the system within Sovereign's brains...screamed danger, this was a utterly foreign aspect to it.
Then as these entities, as they were inching closer to Sovereign, that laid on top of some forges, it's legs clamped at the edges of the infernal furnaces that it settled on, it tried to activate all defense systems, along with its flight module, but something, logically the entity above these creatures, was restraining and shutting down all of Sovereign's combat and survival systems.
But just as the Terminators, Exos, Gatekeepers, Venomcrawlers, and all other vashtorrian daemons, were about engage the intruder, "He" appeared.
In a display of utter submission, all the machine daemons, started backing off, and the titanic silhouette of blade-winged entity, with crimson eyes, and holding a massive pole-hammer in the more "normal" long limb, Vashtorr the Arkefine, he has come.
He has come for his first Elder Daemon candidate, Vashtorr lifted his right arm, pointed it massive index claw at Sovereign, speaking in his vox sounding voice, "Sovereign. Ravisher of countless souls. Frontline of the Reaper Fleet. Destined for death, at the hand of a inferior. I've come to bargain, and grant you power, unlike anything before seen in your world... Interested in my proposal?" Sovereign's "eyes", looked at the...the God, before it and...
