Chapter 1 – Black Isolation

Frozen water fell as heavy, wet puffs obscuring the path Lykrosis was currently following in this unknown area of the Forgotten Shore. His stealth was still up as he ran swiftly through the rock outcroppings, but he hadn't seen any other creatures since the battle that had separated him from his crew. Three nuur'khu had ambushed them scattering the unit, and effectively isolating him as they took cover behind ancient rubble littering the valley. His stealth had destabilized during the first wave due to an armored round piercing his lower left arm, and by the time it was back up the fight was over.

Most of his crew had escaped as they had been on the far side of the battle and moved swiftly when the captain trilled a retreat. He had been left behind with only the nh rv'aan lying forgotten about his greaves. Bright, blue lifeblood was spattered across the area, and his own had mixed with theirs as it dripped profusely onto the dry soil below from his burning wound.

The sounds of distant fighting toward his destination and his wounded state had caused him to reconsider returning to the home caves immediately. Instead, he had decided to find an area to rinse and bandage his wound before taking a longer but well hidden route to the remaining crew.

Lykrosis had been running tirelessly heedless of the growing ache in his arm while searching for a secluded pool to tend himself. Simultaneously, he was leading the easily detected trail of lifeblood away from the home caves just in case nuur'khu decided to track him. There were many recounts of Fallen wounded being captured, interrogated, and tortured by nuur'khu in the hopes of finding their house leadership. He would not be one of them.

Finally, he caught scent of fresh water on the air and it was coming from an area only a little ways ahead and to the right where the land sloped downward between two massive sets of darkened rock. Moving silently forward, he scanned the area and listened intently, but could not detect any activity in the immediate vicinity.

The path between the cliffs was wide but partially blocked on the right side by the remains of a crashed ship of unknown origin. The land had begun to take it back, the local flora surrounding and breaking it apart as they sprouted upwards through the hull in their search for energy. Further down, he could see a set of shallow pools enclosed on all sides by the ravaged cliffs.

Lykrosis crept along the base of the downed ship toward the water when he suddenly froze, the barest of sounds catching his attention. It disappeared, but he waited. There. Again there was a slight scraping. When it came a third time, he realized it was coming from above and barely had time to hide among the vegetation when a figure came into view. Lithe and agile, it leapt off the farthest cliff edge and landed silently in front of the nearest pool facing away from him. Nuur'khu, he thought immediately with disdain, and sure enough a nuur'az followed it down.

He thought it best to leave as even a lone nuur'khu could still be deadly, but its unique form attracted his attention. It was adorned strangely with no visible armor or protective helm like most, only flexible, black fabric covering its seemingly vital zones. Foolish, he thought at the impractical covering. Even more foolish was the fact that it was stripping its only protection off until it stood before him in nothing but its flesh.

He had never seen the flesh of a nuur'khu before, but it seemed similar to his own in that it looked soft yet stretched taught over the underlying musculature. However, unlike his flat gray, it was pure white in color and refracted energy like the frozen water that fell from the skies. He also did not see any sort of exoskeleton or armor plating that would indicate a natural defense.

It slipped into the pool as if to clean itself and kept its back turned, which presented him with a dilemma: attack or leave. He had the element of surprise and this nuur'khu seemed to lack even a hint of intelligence, not that the lowly lifeforms had much anyways, as it had left itself so vulnerable. Although, with only blades at his disposal, his pistol having been lost during the previous fight, he would have to get in close to make the kill.

Cowardice is weakness. His decision was already made, but before Lykrosis could strike he froze for the second time.

Heavy footsteps sounded behind him and he crouched lower into the vegetation surrounding him. His arms flexed readily in anticipation, pain forgotten entirely, and his body thrummed with energy as he prepared himself for a fight. As the footsteps came closer he could see that it was a sdee'al, and he knew that he had lost his chance.

Or… perhaps not.

It moved toward the nuur'khu with its massive blade held at the ready across its front, and its intention was clear in Lykrosis' mind. The two would fight and whichever was left standing afterwards, he would strike down as it would surely be momentarily winded from its exertions. To best a sdee'al or nuur'khu by himself would only increase his prowess and perhaps be enough to alleviate his previous shame.

With that plan in mind he stayed hidden, and with his keen eyes trained on the scene, waited to see how it would unfold. Sdee'al were formidable opponents, just as dangerous as any nuur'khu, and this should prove to be a display worthy of attention. Hunters knew their prey, warriors knew their enemies, and Lykrosis was both of these. Scrutinizing this one on one battle between both his enemies was an interesting learning opportunity. Those who learned and excelled in combat were useful to the Fallen, and he was determined to prove his worth.

This sdee'al was slightly different than others he had seen being deep red in color with numerous black patches, and it was noticeably larger. The traditional full-body armor was battle scarred, and there was additional plating covering the normally exposed mid-section. This one also seemed to have adornments on its armor in the form of shoulder and forearm spikes.

Lying in wait for foolish prey to wander by was instinctual to him, but never before had Lykrosis felt so ready to pounce and make the kill. Electrifying energy roiled throughout his body causing his lifeblood to pump faster through his veins. His upper arms flexed again and his claws tightened around his blades while his lower claws tested the soil beneath his feet. It was wet and heavy from the frozen water but not slick and would provide excellent traction for his short sprint. Seasoned hunters always surveyed their surroundings, and in addition to the footing, the wind was also in his favor. Now was the perfect moment to strike, and yet he stayed frustratingly still.

Why was the sdee'al moving slowly forward instead of charging ahead with its massive blade raised while the nuur'khu was still turned away? It also wasn't being quiet in its advance, and yet the nuur'khu hadn't risen from the water nor turned on its enemy. The behavior of both his enemies was strange and it caused his energy to stutter momentarily in confusion at the scene.

His attention turned from the two to the nuur'az, which unlike its partner, had immediately faced the approaching creature and backed away slowly in obvious fear. The small machine's whole body vacillated as it flicked its gaze between the sdee'al and nuur'khu nervously. He heard it speak, "Hey, you know he's here right?" and although he was unaware of what the words meant figured it was addressing the nuur'khu.

There was no response but the nuur'khu rose from the pool and turned so that it was facing them both.

Lykrosis couldn't help but be distracted by his first glimpse of a nuur'khu without a protective helm. Long, black tendrils sprouted from its head and fell haphazardly around its face and shoulders. It had eyes that were similar in shape and color to his own, but there were only two and they were much larger, dominating its angular face. The nuur'khu mouth did not have mandibles nor visible teeth, which seemed disadvantageous, and he vaguely wondered how it consumed food.

The body was soft and curvy, more similar to his own than the sharp angles of the sdee'al, and its claws were so short to be almost useless. It had two large, unidentifiable mounds on its chest and no visible waste elimination organ.

Its body was lax not tense as if it did not feel threatened by the other creature. Lykrosis looked to its face again and found that its mouth had pulled up at both corners in an expression he was unfamiliar with.

The response from the sdee'al was a low growl as it dropped its blade and grabbed for the nuur'khu in one swift motion. The nuur'khu saw it coming though and jumped out of the way causing the sdee'al to roar. It charged this time, sweeping its claws outward, and missed again when its prey dodged to the left.

The nuur'khu did not attack but continued to jump, sprint, and roll around the hollow with the sdee'al in constant pursuit.

Eventually the sdee'al backed the nuur'khu into a corner and Lykrosis lent forward in anticipation of the final strike. Right before the sdee'al lashed out, the nuur'khu mouth pulled up even farther at the corners and then it dove between the other's braced legs. It hit the water with a loud splash, and then was up on the side of the pool closest to him glancing over its shoulder at the sdee'al.

Then the nuur'khu did something he did not expect; it lowered itself onto claws and knees offering its backside to the enemy in what was clearly submission.

Foolish, he thought again at the display that would surely bring death upon it.

The sdee'al let out a full body roar, its three eyes taking on a bright yellow glow.

Lykrosis thought it would strike, but instead a panel at the apex of its thighs slid back revealing its waste organ. It appeared to be soft but rapidly lengthened and became more rigid as the sdee'al approached its prey until it was a sizeable shaft.

His attention was stolen from the scene by the nuur'az when it spoke again. "Yeah, I'm just going to be over there."

The little machine moved toward him and Lykrosis immediately crouched lower into the underbrush. He did not want it to detect him before the sdee'al had dispatched the nuur'khu.

It passed near him using beams of nuur to scan the ancient ship and spoke quietly although, to whom, he did not know. "Great, now I have to find something to occupy me while I pretend that she isn't having sex with the knight… again. Hmm, let me scan this ship for the thou—" but it abruptly cut off and backed up with its eye trained on him.

The reaction was telling; it had discovered him. However, it didn't do anything other than hover just out of his reach before it moved away to scan something else.

Lykrosis waited to see what form of trickery it was up to, but it paid him no attention. Aware that it could still be a ruse, he left his audio receptors trained on the nuur'az, but focused his eyes back on the pair.

The sdee'al was on top of the nuur'khu now practically crushing it into the ground while its claws grasped at the soft body. Light scratches and trails of lifeblood appeared wherever the claws swept over the flesh, and the nuur'khu made small noises in response. The larger creature bit at its prey's neck and the nuur'khu claw slipped behind its head; he thought it was to ward it off, but it only pulled the sdee'al closer.

Lykrosis did not understand what was happening between the two. It was the strangest form of fighting he had ever seen and neither seemed to be trying to win. The sdee'al could easily tear its prey apart in this position, but the claws never bit deeply into the flesh. It growled ferociously but handled the nuur'khu gently almost as you would while polishing a savored blade.

A strong gust of wind blew various scents up from the pair, some familiar such as the intoxicating smell of lifeblood, of wounded prey. There were others he couldn't identity, so he rose up on his haunches and took in the scent more fully. Whatever it was, it was also pleasant, and the combination caused a small stirring within his abdomen that he recognized as desire. Although, desire for what, he did not know.

Eventually, the sdee'al let up. It moved into a kneeling position, and then pulled the nuur'khu harshly back against it so their hips were flush. The nuur'khu cried out loudly in what he assumed was pain, but it didn't try to pull away.

One of the sdee'al large claws dug into its backside and the other wrapped around its middle creating small punctures in the soft flesh. The larger creature pushed the nuur'khu forward, and then jerked it backward, which caused its prey to cry out again.

They started to rock against one another, their bodies moving back and forth in opposing motions, and they slammed together roughly. The nuur'khu gasped at sharp thrusts and moaned almost continually, but it wasn't in pain. With his keen eyes picking up on minute details, he could see that it pushed its hips backwards to meet the sdee'al and its pulse was racing from the exertions. The nuur'khu was… enjoying this; they both were in fact. Each noise that escaped the nuur'khu resulted in an enthusiastic thrust from the sdee'al and an accompanying grunt.

The pair kept at it for many moments, their pace never faltering, always back and forth. Then, something changed. The nuur'khu blunt claws scratched at the ground as its body went rigid, and then it screamed. Long and loud, it screamed and writhed while the sdee'al continued to ram into it from behind.

Another intoxicating, yet unidentifiable, aroma permeated Lykrosis' senses, but this one caused a sharp clenching in his groin in addition to a surge of desire.

The screaming turned to whimpering and the writhing to shuddering as the nuur'khu finished whatever it had done, but still the sdee'al moved. The smaller of the two collapsed against the ground and without its help, seemed to give the sdee'al more trouble moving in this position. It instead picked the nuur'khu up holding its back flush against the sdee'al front, and Lykrosis finally saw what was really happening. The waste organ, still long and firm, was inside of a hole in the nuur'khu that it had either made or was already there.

He did not understand the purpose but was instantly revolted by the knowledge, and the desire he felt disappeared. What was the sdee'al going to do, eliminate inside of the other?

In this new position, the sdee'al now moved the mostly limp nuur'khu up and down upon itself causing the shaft to move in and out over and over again. Its one claw stayed wrapped around the smaller creature's waist while the other moved to grasp at the mounds.

The nuur'khu jolted at that, and then began to moan and whimper again.

There was another period where they kept moving at the same moderate pace, a seemingly unnecessary repetition of the whole process. That was until he noticed that the sdee'al behavior was the one to change this time. Its claws clenched down on the nuur'khu body, tearing the soft flesh as it increased its pace and ferocity. It slammed the nuur'khu down upon itself to the hilt, growling heavily, and causing the mounds to bounce from the force.

The nuur'khu only seemed to enjoy the rough treatment more, its own claws scrabbling at those of the sdee'al. Ragged screams escaped its throat again and the writhing that accompanied them.

This time, something similar happened to the sdee'al as well. It moved its smaller partner up and down several more times before it crushed the nuur'khu down as far as it could go, and then it let out a deafening roar. Its body gave small shudders and the waste organ pulsed inside of the nuur'khu. They both rutted against one another, screams mixed with roars, claws scratching at each other's flesh, and that organ throbbing over and over.

Sure enough, rivulets of thick, black liquid ran down their thighs and dripped into the water below. Disgusting, he thought as his mandibles pulled back in a silent snarl.

The spasms and noises fell away leaving both panting heavily from the apparently taxing amount of work the display had required, but still the sdee'al pumped the nuur'khu full of liquid.

The sdee'al recovered more quickly than the nuur'khu and moved with its smaller partner still impaled to sit with its back against the left cliff wall. The liquid was now gushing out in thick globs, yet the organ throbbed again, and he wondered how many moments it took to empty, if that was what it was doing. Lykrosis was also surprised that the fluid had a slightly sweet smell to it and not the putrid odor he was expecting.

The nuur'khu stirred with a slight moan, trying to lift itself off the shaft. Both the sdee'al claws moved to its partner's hips and slammed it back down roughly with a growl. Another shout from the nuur'khu was the result as its head fell backwards, eyes closed and arms spasming. Deep, slow breaths racked its body before it twisted to look at the sdee'al with that same expression it had had before the display. Apparently content to stay put, not that it had a choice, it lie backward against the massive creature and relaxed.

The sdee'al waited to make sure the nuur'khu wasn't going to try to get off it again, and then relaxed into its position as well. It seemed like many moments passed before the pulsating shaft slowed, spurting the last of its fluid, and then lie quiet. They continued to rest while the organ reverted to its softer state and slipped out of the nuur'khu.

Lykrosis heard a snick that he figured was the panel closing, which prompted the nuur'khu to rise. The sdee'al followed suit, and then they parted as if nothing had happened. The larger creature picked up its blade before departing back up the long path from whence it came, and the smaller returned to the pools to remove the black fluid and lifeblood.

While the nuur'khu was still cleaning itself, the nuur'az returned and began speaking, "Did you have a good time? No, don't answer that, I really don't want to know. Anyways, we have another visitor." There was a pause before it started again, "Of course you already know. What are you going to do about it?" Another pause and it lasted many more moments that the previous one. "Great. No answer. You know you are the most frustrating creature I have ever met. Sometimes I think I should have just woke another guardian."

The little machine remained silent after that and watched while the nuur'khu replaced its stripped garments. The first fabric slipped on over its head, obscuring most of the mounds from view, but pushing them up at the same time so the visible tops were pronounced. There was cord along the front that followed a crisscross pattern downward and was used to tighten it around the nuur'khu frame. The second covering was a tiny piece of cloth that slipped on through legs holes leaving everything bear but the folds between its legs. The last piece covered its entire backside with long pieces of fabric that fell to the ground but only cut across the thighs in front.

The nuur'khu finished its preparations, gave the little machine that same expression, and then started up the path. It walked leisurely, flicking its eyes around as if taking in its surroundings. When it reached the ship, it trailed its claw tips through the vegetation, brushing individual stems and leaves like it was testing them.

The claw passed close to him, never touching, but it still caused his lifeblood to pump rapidly, an almost electrifying feeling filling him.

Lykrosis watched with interest as it strolled up the path only just realizing he had missed his opportunity to make the kill. He cursed inwardly but for some reason, he had hesitated. His eyes followed the nuur'khu to the apex of the slope, its machine partner trailing closely behind, and then he was alone.

Fallen Language

The information in this section has been completely made up by me. Bungie has given us Fallen glyphs, but no actual words (outside of a bit of dialogue in game that you don't get text for). I have used a system I devised a long time ago for creating new languages and applied it to the guttural speech as well as clicking, trilling, and growling we here from Fallen during gameplay. Listed in order of appearance:

Nh Rv'aan – literally means no soul. This is a term for the dead but it is specific in that it refers to those that are soulless.

Nuur'khu – literally means lightbearers. This is what Fallen call guardians.

Nuur'az – literally means tool of light. This is what Fallen call ghosts.

Sdee'al – Hive Knight

Nuur – guardian light
