Inkor'sea

Overview

The Inkor'seans are a species of unknown origin. More recent observations show that they are not of one species, but of many. Most of them are of a humanoid nature and appearence, but also a lot of specimen with four or more limbs or up to three heads or eyes or whatnot.
They appear to be out of bio-organic and synthetic materials like implants infused into their bodies for whatever reasons: conditioning, enhancing, control or more darker undertakings.

History

It is not much known about the Inkor'seans. Scholars, scientists, scouts, military leaders and even the Einherjar are trying to find more and more evidence, hints, clues, and intel about them.
It is clear that they are old. Really old and their technology varies from old ballistic weapons like Humanity uses to laser- and solar-powered weapons like the Lyranians and Anthraxian uses.
After the latest armed incidents it is clear that the Inkor'seans are not from one species, but consists of assimilated worlds and their biomass, meaning animals and the inhabitants. However they have done it, the Inkor'seans created - willingly or not - the Tomb Worlds.
Scouts, explorers and other parties are now diving deeper into the history of those foes. To know the enemy is the first step to defeat them.

"How secret do you wanna keep this?"

"Very." Valeria nibbled at her lips and Alira kissed her to distract the Empress. "Thanks, love. What is your thought on this?"

"Well" Alira sipped at her tea "the Inkor'seas are our foes, right? We should gather information, lock them away until a specific time and then hold a press conference. We already lost three worlds and can't withhold those information any longer. Freighters are bringing rumours, pictures, scans. Privateers are commencing scout operations and you know how good the private sector is with tech-dev."

"Yes, I know..." Valeria looked at John who was hovering in front of the large front of windows, surrounded by a few dozens of holographic fields. Every field displayed different things; some were databases, others news sites, some had Deep Web pages open, CCTV feeds, military reports or various frequencies of... well, data transmissions. "John? What are you thinking?"

"I think we should publish at least a few information before the rumours are taking over and more people doing their own research." He waved with his hand and the holographic fields folded themselves to a neat stack like they were folders. Then John turned, still hovering, to his wife and his partner Valeria. All three had changed into something more comfortable and looked like they had a sleepover-party. "I'm going to design a high security server cluster for this. We store all of the information there and only release a few. And we should create a taskforce or maybe an entire department for that."

"Agreed.", said both women, grinned at each other.

Goals

The goals of the Inkor'seans are relatively easy to explain, but hard to contain. The goal of the entire species consists of three steps. At first they want to ██████████████████████████████, then they need to perform ███████████████████████████████████ with enough ███████████████ to ██████████████████████, so that they can ██████████ and ████████████████████. Which is presumably our █████. From what we know, ██████████ and ██████████ want to ██████████████████████████████ and ███████████████.
If you wanna read this, do it, but this is the same paragraph not redacted. You are warned, heavy plot/lore spoilers!

The goal of the entire species consists of three steps. At first they want to gather a lot of biomass from every species, then they need to perform a Ritual of Dimension Piercing with enough biomass to open up a rift between dimension, so that they can bring over their Unspeakables and let them rule over the galaxy. Which is presumably our final death. From what we know, Julitharexa and Julitherdona want to divide the Milky Way between them and dominate every other species.

Weaponry

The weaponry of the Inkor'seans consists of the parts they have assimilated from other species. So one can find ballistic weaponry from the Humans, solar-powered weapons and generators from the Lyranians, Pinchers from the Anthraxians, Chronomancer technology, Sylphid filtration systems, Naiad water-pressure-weapons, Simiiforc blades, axes, clubs or Carabellan armour.
Their armour - if one could call it that way - consists of everything the specific being of an Inkor'sean can attach to their body. Quite literally sometimes, since they don't care about pain. If it fits, it gets attached or infused into the flesh.
In addition to their exo-skeletons, their implants, their portable - or built-in - generators and their sometimes into the arms or legs infused weapons they are mostly stronger, faster and more accurate than every other species.

Travel & Warfare

Just like their armour and weaponry they travel with what they can assimilate from the worlds they conquer. Some of the vehicles like human armoured trucks or Lyranian Hor'An Hal'ha are either to small or not significant enough to operate on their own, so they are either deconstructed and their parts used in other ships or just integrated into other ships.
To cross the vast distances of space the Hivemind of the Inkor'seans had developed a similar method as Humanity to travel with FTL: they rip a hole into the fabric of space, rush through it and come out on the other side. Since they've disabled - or haven't cared - for the security measures a good amount of their species dies through the entire travel and screams in not-ignorable pain, they call it "the Screaming Void". Humans call it a "Scream Jump".
If they land on a planet, they do it with drop pods to surprise enemy forces and overwhelm them with their mass. They don't care if they die or live, the mission comes first. If the defenses are broken, larger drop ships gather the inhabitants of the planet, the animals and a lot of plants from the surface before bringing them up to the fleet.

Assimilation & Tomb Worlds

Once they have gathered everything, they deploy something which is commonly known as a Burner. This thing is basically a radiation bomb which destroys every living cell on a planet and creates a Tomb World. What remains are empty buildings, rotting soil, hot winds, dust, and silence.
The animals, plants and people are brought to the homeworld of the Inkor'seans, before the Hivemind and from there into the labs. There they are stripped of their clothes - animals of course not - and tossed into a huge bassin where a corrosive liquid melts them together into a bloody mess of goo.
This liquid is put into another bassin where it is stored away for safe transport because the Homeworld is not large enough to store that amount of biomass. That biomass is cared for, stirred, frozen, heated up, depending on the world it is stored, waiting to be used in the Ritual of Piercing Dimensions.

War Tales

"Nothing."
"What do you mean with nothing?"
"Sir, there is nothing here."
"I can see that."
"No, Sir, you don't understand: there is literally nothing here. Not even germs. This entire planet is dead. Wouldn't be surprised if the core is dying either."
"So it is true that the Inkor'sea were here?"
"Just so, Sir."

— Scientist with the military leader on a Tomb World excursion

"We've sent in the heavy artillery. We've sent in the heavy tanks. We even sent in napalm, clusterbombs, railguns and a barrage of MOABs. They wouldn't stop. We couldn't hold them off. And if you haven't seen them, you wouldn't believe how...how... a horrormovie coming to life. Flesh with metal and instruments and blinking lights, howling and screaming while firing at us...
We threw everything at them. I even had to change my weapon because the barrel overheated and I couldn't shoot anymore. We were lucky that John Roland René Sullivan was scheduled for a conference, otherwise... he ... I don't know what he did, but after the blindling light and the heat the Inkor'sea were just gone. There was nothing left of them but dying embers."

"This is madness."
"Hm hm."
"How are we going to conquer that?"
"Correct question...so much death. What can men do against such reckless hate?"
"Don't you quote Theoden to me."
"Sorry. But the question still stands."
"We have to find their leader or leaders."
"And then what?"
"You go full Bomberman. We can't negotiate with them."
"Agreed."
