Exploration Ship #12/7 relaxed its space-time bubble and fell back into normal relativity. Behind the thick disk-like plate that divided the craft in two, various pieces of equipment glowed bright electric colours, gradually fading as the seconds past. Thermal-dump panels then became more noticeable, glowing red hot against the star-speckled background. Meanwhile the front of the craft basked in the golden glow of a nearby star, which was now just a light-hour distant. There wasn't much to see from (what passed as) the ship's bridge. Admittedly, the crew were more used to visiting smaller, dimmer red stars, but they had seen it all before. After years in space, the procedure was drilled into them. Various systems had just failed, as they always seemed to after a 'run'; the ship's interface hummed various warning sounds at low frequency, something the Satellian crew regarded with none of the intended urgency - it had become the familiar heartbeat of the ship.
It was #12/7's turn to play the lead - one of the most space-worthy ships would skip ahead of the others and lurk on the edge of the target system, while recharging its drives and making preliminary observations. By the time the rest of the ships arrived, the lead ship would already be sending data about the nearby planets, and would be able to run to the assistance of any ship in difficulty. Or at least, that was the idea.
Eventually, the astrological sensors were activated, confirming the ship's position against the most obvious stars. But the planet-finding sensors had failed again, as had the communications equipment. The ship's basic optical sensors and anti-collision radar could not detect the multiple large alien craft, nor could the crew be aware of the radio chatter from numerous alien habitats in the system - the crew were fully occupied dealing with a coolant leak in the bowels of the ship, while the Captain had coated herself with an EVA membrane and had crawled outside to tie down some equipment pods that were in danger of floating loose again. Meanwhile the ship's faulty communications equipment began randomly broadcasting detailed real-time data on the ship's temperature control system into deep space on a variety of frequencies...

Exploration Ship #6/7 returned to normal relativity and immediately began to pitch and roll wildly as its stabilizers fired uncontrollably; just one symptom of an auxiliary power unit explosion. Inside, the crew struggled to reach various override switches against the constantly-changing forces of acceleration. Distorted warning sounds and flashing flights added to the sickening disorientation. The holographic 'avatar' of the ship's computer appeared at random intervals, orating less-than-helpful speech bubbles of garbled computer code. It was an embarrassing sight, as seasoned space travellers flailed all six limbs like first-timers in zero-g; there was just a hint of panic amongst some of the younger crewmembers, including a certain communication specialist by the name of Murrumue Ulunn, who couldn't help but close his eyes and retract his mouthparts as far as they would go. But in the midst of the chaos, something bothered him, something he had just seen in at the edge of his vision... The special signals display was ablaze with top-priority alerts.

Engineer Ship #1/7 had a comparatively smooth re-entry into flat space. The Fleet Captain, a venerable quadruple-centenarian by the name of Jurninn (Satellians tend to lose their miscellaneous family and regional names as they climb in reputation) delicately stroked his antennae as he read through the Ship's status report. The fleet currently had no method of faster-than-light communication, other than using the ships themselves to form a relay. It would be about an hour before the status of the whole fleet could be known. Procedures were lax, and the fleet had become badly scattered in the previous months - some ships had already begun the long journey home, plotting a course to intercept and cannibalise the various probes and automated facilities that had been left in their wake.
#1/7 was the newest and biggest ship, almost a third of a kilometre long, carrying a forest of robotic arms and stockpiles of replacement components. But there was only so much that could be done out here. Every ship was in need of a full mechanical overhaul at a proper engineering base. The nearest of these was now over three thousand light years away. It had taken a special effort to regroup the remaining ships for these last few rolls of the dice, before heading back. Yet, belatedly, the fleet was starting to act like a single Kinship, with a single purpose. The great mythical 'Signal' had yet to be confirmed, but at their last stop they had detected something else - faint, anomalous radio signals from a nearby star...
So here they were. Several of the nearest ships called in within a few minutes - most had minor technical problems, which was nothing unusual. What was unusual was the omnipresent background chatter, corresponding to no known encoding protocols.

The crew of #6/7 had managed to halt their ship's erratic manoeuvring, and were now struggling to tidy up the various boxes and pieces of equipment that had gone flying loose about the interior. One unfortunate crewmember was receiving treatment after being impaled on a large screwdriver-like implement; her inner skin had not been pierced, which all were thankful for, not least because bodily fluids made an unpleasant mess in micro-g. Meanwhile, crewman Murrumue Ulunn was literally glued to his special signals console, his body slowly oscillating with excitement. The display was, however, blank - save for a few smaller screens, rehashing a corrupted version of the last received alien signals. Power had gone out to various core systems, and the Captain was quite clear that the inter-fleet communications should be brought online first.
The communications dish focused on what was believed to be Engineer Ship #1/7 - the largest ship-like object in the vicinity - and broadcast a rather blunt request for various spare parts and the assistance of an extra engineer team. It was however broadcasting to an alien vessel.

Fleet Captain Jurninn folded his front two limbs together in front of his eyes, a gesture of both contemplation and an acknowledgement of forces beyond his control. Big questions remained over the status of the fleet, but it was clear that some ships had life-threatening problems. Perhaps the last run has been just a little too long and taxing - but shortening them meant more stops and starts, which was equally bad for the fleet's bubble drives.
The biggest concern, though, was the visual and infra-red detection of various large, artificial objects on an intercept course... And preliminary analysis of the background chatter suggested that it was indeed some kind of deliberate broadcast, containing both numerical patterns and what seemed to be... alien speech. Jurninn's limbs stiffened, raising his torso slightly, as he heard the distorted sounds played over the ship's intercom, shifted lower in frequency for the benefit of his internal Satellian ears. The accompanying crewmembers were likewise frozen in place, save for their mouthparts and eyes, which turned to face each other. Jurninn was a comforting presence for all of them, exuding an aura of determined tranquillity. Even the ship's cheerful system's avatar maintained a dignified silence. For a moment they allowed themselves to bask in the significance of it all.
The spell was broken by a sudden warning-rumbling from one of the computer consoles. A younger crewman overcame his discomfort to suggest there were signs of... weapons... being trained on the fleet, a suspicion soon reinforced by the nearest ships. Who would put weapons on a spaceship? Was this a test? How should we react?
They had expected any aliens they met to be older, wiser, benevolent - looking upon them as innocent children, or at worst, ignoring them as insignificant. They would be holding all the keys. They would have no need for violence. No aggressive or ignorant species could ever develop true sentience. But of course, Jurninn thought to himself, ever since we started venturing into space, these things had not been turning out according to expectations.
Jurninn lapsed back into stroking his antennae, leaving his crewmembers to exchange opinions, while he used one of his free rearward limbs to dial up a list of the fleet's heavy-duty tools on the main display. He should at least give a courtesy consideration to the prospect of defensive manoeuvres, he told himself. Each ship was fitted with welding gear, that was a start. Most also had a workable mining laser, able to bore holes in non-manoeuvring space rock. Several ships including the #1/7 had stockpiles of nuclear explosives totalling several megatons, again designed for asteroid modification. But they needed to be delicately placed by drones, or EVA teams. Perhaps the most effective weapon would be the ships themselves - the core hulls were armoured to resist energetic collisions with space rocks, or each other.
No - It was all too surreal - too sudden. Nothing in his 449 years had prepared him for this. What he knew was rationality - the politics of entwining individual interests for the greater good. Logical progression. Enlightenment. Self-realisation and expression.
Semi-consciously, he had been listening to the chatter of his crew and the nearby ships. It all added up to the same conclusion. He provided a welcome interruption with his authoritive voice.
"Our priority is to raise #6/7."
"... #6/7 is still not responding. Long range visual suggests multiple system failures."
"Keep trying. The universe help us..."
The crew turned to face him once again, their lower body postures suggesting confusion and anxiety.
"This is the moment we put our communication specialist to the test."
Some of the crew nodded their front ends in a gesture of confidence. Others did not.
"For now, all other ships hold position. No sudden moves, or power flares. Every gesture counts now. We must assume they are watching everything."
"What if -"
Jurninn fixed all limbs to the floor, momentarily bouncing in the feeble artificial gravity provided by the ship's spin. He took a moment to gather himself.
"If, then, our contingency is #12/7. If we are... on the receiving end of hostility, our contingency is to detract attention from #12/7, by any means. We still need hours to recharge our drives. We can't run yet, but they can. If the worst happens... We protect them. Someone must get home."
"... #12/7 is also not -"
"Yes... We have no choice but to hope."

Still around twenty light minutes from the rest of the fleet, and offset some distance above (or below) the system's orbital plane, the Captain of Exploration Ship #12/7 was finishing the last of her repairs to the outer hull storage compartments. It had taken longer than expected. The oxygen belt was running low. The magnetic feet pads seemed a little too strong today. She was tired, and perhaps slightly delusional - extended sessions in an EVA membrane tended to do that to her. She had to do a reality check when she saw a fellow crewmember crawling out to greet her, covered in a similar bright turquoise membrane. Apparently even the local intercom was offline. Through standard sign language, she established that her presence was urgently needed inside, something to do with coolant fluid seeping into the core electronics - not good. She had just started for the airlock when space suddenly got brighter. The hull was now bathed in blinding light. Above, something very big and shiny was coming closer...
