Author's Notes: Most vehicles seen in mass effect seem to be of human design, with a few exceptions. So I hope you don't mind me just changing the origins of a few. In this chapter, the Kodiak, and the A-61 Mantis Gunship are of Turian origin.

Matriarch Benezia crossed her arms, the old asari deep in thought. The fleet was awaiting for the dormant relay that led to the Exodus Cluster to finish activating. In just mere moments, the relay would come to life, and the crew would set foot in an unknown and unexplored area of space.

"The verge of the unknown is never an easy place to stand," Nihlus mused, his voice low and calm. "Even the bravest of souls can feel fear at the edge of the abyss, not knowing what lies in wait on the other side."

"I have faith that the goddess will watch over and protect us," Benezia replied, her expression determined and confident. "The crew has proven that they are capable and resourceful. Whatever lies ahead, we will overcome it."

"Your words are true," Nihlus acknowledged, his mandibles widening in a grin. "Your presence alone is enough to inspire courage in the crew. They are ready to face the darkness and whatever else may lay in the stars, with you at the helm, guiding them onward."

Benezia's eyes crinkled in amusement. "The same could be said of you, Spectre. Your reputation and skill precede you. You are an invaluable asset to the expedition, and the crew knows that you have their safety in mind. That alone is worth a great deal."

Before the two could continue their conversation, Drutus approached them from across the CIC, the turian's stride measured and purposeful. His mandibles twitched in anticipation. "We're receiving the signal from the secondary relay," he reported, his voice tinged with excitement. "It's time to depart."

Benezia and Nihlus exchanged a knowing glance, the weight of the moment hanging in the air. This was the culmination of months of planning and preparation, and the beginning of a new chapter in the history of the galaxy. "Send the order to the fleet," Benezia instructed, her voice steady and commanding. "We set out immediately."

Drutus nodded and strode away; his movements filled with the confidence and purpose that came with a seasoned soldier. The command center was abuzz with activity, the crew moving with practiced precision and efficiency. The hum of the engines rose to a crescendo, and the ship surged forward, the other vessels following suit.

As the relay came to life, a shimmering blue light enveloped the fleet, and they were pulled into the depths of the unknown.

Exodus Cluster

Unknown system

The THS Unconquerable shuddered as it emerged from the relay, the rest of the fleet following close behind. The ships formed a tight formation, their sensors scanning the surrounding area for any signs of danger.

"This is the Captain speaking," Drutus announced over the intercom. "All crew remain vigilant. We are in uncharted territory and must be prepared for anything." The bridge was tense, the crew's eyes glued to their screens, waiting for any sign of trouble.

"Have the SNV Nadarth keep pace with the main fleet," Benezia instructed. "Make sure they maintain stealth and are undetected."

"Understood, Matriarch," Drutus replied, the captain's fingers dancing across the console, sending the necessary commands to the salaraian corvette that was acting as their covert support.

"The system we're in seems to have nine planets, all orbiting a single sun." A navigation officer commented, his eyes glued to his screen. "There's an asteroid belt in the middle of the system, but apart from that, nothing else of note so far. Scanners haven't detected any anomalies or strange readings. All ships in the fleet are reporting in that everything is a-okay."

"Good," Benezia replied, her demeanor stoic and unwavering. "Send out probes to gather data on the system. I want to know everything there is to know about this place, and then, once we have a clear picture, we'll decide on a course of action." The crew set to work, launching probes that sped off into the depths of the system, their sensors scanning every corner, gathering information that would prove vital in the coming days.

Patience was key. Despite the excitement and anticipation of the crew, Benezia knew that rushing in blindly was a recipe for disaster. She would not sacrifice the lives of her crew and the future of the galaxy for the sake of haste.

They would bide their time, and when the moment was right, they would act, and the secrets of the unknown would be revealed, one way or another.

Leaning against an observation window, the glass cool to the touch, Wrex let out a grunt of irritation. The view of the dark vacuum of space was dull, and the old Krogan wished that they would land on a planet already and stretch his legs. Space was never his preferred method of travel, the endless black abyss not doing much to excite the battle-hardened warrior. There was a chance that a species hostile to the council could exist in the system, but Wrex was doubtful. Chances were that this would be a quiet and boring mission.

"See anything interesting, battle master?"

Glancing to his side, Wrex's eyes met with Captain Kirrahe, a salarian who'd been keeping tabs on him ever since the Krogan had come aboard. Normally he wouldn't appreciate being spied on, but in this case, he understood. To have a Krogan of his stature on a ship full of various races, some of whom might be a bit uncomfortable in his presence, was not something to ignore.

But Wrex wasn't some young hot-blooded whelp. He had control and discipline and could hold his own in the company of others. Didn't mean he enjoyed the constant spying, but the occasional conversation was a decent way to pass the time.

"Not much of a view." He grunted, turning back to the stars. "Give me a battlefield to fight on. Now that's a view." The corners of his mouth turned slightly upward. "Much better than staring at the void, and hoping that something interesting pops up on the scanners."

"Personally, I prefer the stars," Kirrahe admitted. "And the beauty of the vast expanse of the universe, full of wonders to behold and marvel at. Truly a sight to see."

Wrex let out a laugh and shook his head. "Salarians and their damn curiosity. Always wanting to know more and expand their knowledge. Well, to each their own." Turning, he looked at Kirrahe. "I assume you're just checking to see that I'm not causing any trouble, right?"

Kirrahe's posture was relaxed, and the salarian nodded. "Something like that. Although, truthfully, I was hoping to have a conversation with you. One warrior to another, if you catch my meaning."

Raising an eyebrow, Wrex couldn't help but be curious. "What's on your mind, salarian? Don't tell me you're getting cold feet. If you're looking for reassurance, I'm not the krogan to talk to."

"On the contrary," Kirrahe replied. "I have no doubts about the mission, nor the competence of the crew. But I must admit, I am not overly thrilled at the prospect of a confrontation with a hostile alien race. War is not something that should be taken lightly, and the cost can be great."

Shrugging, Wrex couldn't disagree, but a small chuckle escaped his lips. "Not too keen on having to uplift another race to do your fighting?" he mocked, a sly grin spreading across his features.

"You have a point, Urdnot Wrex," the salarian conceded. "The uplifting of the krogan during the Rachni Wars was a decision made out of desperation. And the outcome was not something anyone could have predicted. But that is the past, and we must learn from our mistakes."

"That's easy for you to say," Wrex spat, his eyes narrowing. "You didn't have to live with the consequences. My people are cursed, thanks to the genophage." Clenching his fists, he felt the familiar anger bubbling within him. "You have no idea what it's like, to watch your people die, unable to do anything to stop it. To know that your race is slowly dying, and there's nothing you can do."

Silence hung between the two of them for a moment, the tension palpable. Finally, Kirrahe spoke. "You're right, I don't know what it's like," he admitted, his voice soft. "But I do know that the choices we make, both in the past and the present, have consequences. And we must learn to live with them, and find a way to move forward, no matter the cost."

Wrex considered the salarian's words and took a deep breath, trying to calm himself. "You're a wise one, Kirrahe," he finally said. "Too bad wisdom can't bring back the dead." Shrugging, he let out a sigh. "At least you're honest. That's more than I can say for most of the people on this ship."

"Thank you, Wrex," the salarian replied, a hint of a smile on his face. "Now, if you'll excuse me, I have some duties to attend to. But I'm glad we had this talk." With that, the salarian left, leaving Wrex to his thoughts.

Looking out at the vastness of space, Wrex couldn't help but feel a sense of emptiness. He had seen and done so much in his long life, but in the end, what did it all matter? He had lost everything, and now he was just a relic of a bygone era, a relic that no one cared about anymore.

Shaking his head, he turned away from the window and started walking. Maybe a drink would help take his mind off things. It was worth a shot, at least. Anything was better than staring into the cold, uncaring void of space.

Tapping the glass of her empty cup, Tali stared at her omni-tool, watching the clock tick slowly by. "Keelah, the wait is killing me." She groaned, setting her empty cup on the table. "If the captain doesn't have an announcement soon, I'm going to lose my mind."

"Relax Tali, it's only been a couple of hours. They need to scan the entire system before they decide where to go, and that takes time," Garrus chided. "Besides, we're all in this together. If the wait is driving you crazy, imagine how the rest of the crew feels."

"I'm aware, but that doesn't mean I have to enjoy it." Tali sighed, leaning back in her chair. "It's just frustrating, is all. I've spent my entire pilgrimage waiting for something like this, and now that it's finally happening, I feel like I'm being kept in the dark."

"Don't worry, the captain will let us know when he has something to share," Garrus reassured her. "In the meantime, try to relax. Maybe have a drink or two. It'll take the edge off."

Tali shook her head. "No thanks, I'll pass. Drinking and dextro food don't exactly mix well. Trust me, I've learned that the hard way. But maybe I'll have a few snacks to take the edge off. Something to take my mind off the waiting, at least."

"Excuse me, is this seat taken?"

Turning, Tali and Garrus saw an unfamiliar asari looking at the Quarian, the seat next to her was the only one unoccupied in the mess hall. "Oh! Go ahead, please have a seat." Tali smiled, shifting her chair to give the newcomer some more space.

"Thanks." The asari grinned and sat down, her gaze lingering on the pair. "My name's Liara T'soni. A pleasure to meet you."

"My name is Tali'Zorah nar Rayya," the Quarian introduced herself, her eyes curious and attentive. "This is Garrus Vakarian." Gesturing to her friend, Tali watched as the turian offered a friendly nod, his mandibles widening in a smile.

"Nice to meet you," Liara said, her gaze drifting from Tali to Garrus and back again. "I hope I'm not interrupting anything."

"No, not at all," Tali assured her. "We're just chatting and passing the time. Waiting for the captain to announce where the fleet will be heading, or if he'll say anything at all."

"Ah, yes. The suspense is killing me too," Liara confessed, a nervous chuckle escaping her lips. "I can't believe that we're here, exploring an uncharted system. It's an incredible opportunity, and I'm eager to see what we discover."

"Me too," Tali agreed, her excitement bubbling to the surface. "Who knows what's waiting for us out there in the stars? It could be the discovery of a lifetime or the start of a whole new chapter in galactic history."

"Indeed, the possibilities are endless," Liara mused, her eyes twinkling with wonder. "I just hope that we can make the most of this opportunity and use it to better understand the universe around us, and maybe even improve the lives of the people in it."

"Well said," Garrus interjected. "It's important to remember that, in the end, we're all in this together, and the discoveries we make can benefit everyone, not just a select few."

"Exactly." Liara nodded, her expression thoughtful. "The galaxy is a big place, and we need to work together to make the most of it. Otherwise, we'll just be fighting over scraps, and that's no way to live."

Tali couldn't help but grin, her spirits lifted by the conversation. It was nice to know that there were others on the ship who shared her enthusiasm for exploration and discovery.

"I wonder when we'll get the green light to start poking around the system," she wondered aloud. "Maybe I'll be allowed on the first ground team, and get to examine a new planet. It would be an amazing experience."

"I'm sure the captain will make an announcement soon," Liara reassured her. "Until then, why don't we keep each other company and pass the time? Maybe share a few stories about our experiences and backgrounds."

"Sounds like a plan to me," Garrus replied, his tone warm and inviting. "Let's get to know each other a little better, and maybe we can even form a friendship out of this. Who knows, maybe we'll end up making history together."

With a collective chuckle, the three of them settled in for a long, leisurely chat, their conversation flowing freely and easily. Despite the uncertainty of the mission, they found solace in each other's company and a sense of camaraderie that would carry them through the trials and tribulations that lay ahead.

"Scans of the seventh and largest planet in the system are complete, Matriarch. It's a gas giant. Hydrogen, helium, methane, and hmmm..." the ship's sensor operator's voice trailed off, his eyes narrowing as he squinted at the readout.

"What is it?" Benezia asked, her attention piqued by the operator's hesitation. "Is there something unusual about the planet?"

"It's... odd." The navigator's brows furrowed as he studied the data. "Something is orbiting the planet."

"A moon?" Nihlus suggested, his interest piqued as well. "That's not too out of the ordinary, is it? Gas giants usually have a large number of satellites orbiting them."

"Yeah, a lot of moons." the operator confirmed. "Though, that's not the unusual thing. I'm picking up an artificial energy signature coming from the biggest of the bunch, and a fairly large one at that. Not to mention the fact that the satellite is emitting a powerful pulse. Whatever that object is, it's not natural, and it's drawing an incredible amount of power."

Benezia and Nihlus exchange a worried look, the implications of the navigator's report weighing heavily on their minds. If the energy signature was indeed artificial, it could mean that the planet was home to an advanced civilization or, worse, a hostile force that posed a threat to their mission and their very survival. They would have to tread carefully and investigate the source of the energy signature with utmost caution.

"How close can we get to the planet without risking detection?" Benezia asked, her voice firm and commanding. "We need to gather more information before we decide on our next move."

"We can get in pretty close, Matriarch." the navigator piped up. "The gas giant's magnetic field is strong, and it should be enough to mask our approach. We can stay at a safe distance and use our sensors to gather as much data as possible."

"Excellent." Benezia nodded, satisfied with the plan. "Notify the rest of the fleet. Exercise caution, and avoid any unnecessary risks. We can't afford to be careless, especially in the face of the unknown. Our safety and success depend on it. Is that understood?"

"Yes, Matriarch." the navigator replied, his tone solemn and respectful. He turned his attention back to his console, inputting commands and directing the fleet to their new destination. As the ships moved in formation, their engines thrumming with power, Benezia and Nihlus exchanged a knowing look, their thoughts mirroring each other's. They were about to embark on a mission that could have far-reaching consequences, and they had to be prepared for anything, no matter the cost.

As the ship approached the gas giant, the crew was filled with a mix of excitement and apprehension. They had been briefed on the situation, and the discovery of the unknown object was a tantalizing mystery that had captured their imaginations. But they also knew the dangers that lurked in the vastness of space, and they were on high alert, their senses sharp and their reflexes honed to perfection.

"Entering orbit of the gas giant," the navigator reported, his voice tense with anticipation. "Activating scanning systems, and commencing search for the artificial energy signature."

The bridge was silent, save for the faint hum of the ship's instruments and the steady breathing of the crew. Their eyes were glued to their displays, their fingers poised to react to any threat that might arise.

Coming into view, the massive orange gas giant loomed in the viewport, its swirling clouds and roiling storms creating a breathtaking vista that was both awe-inspiring and intimidating. But the crew's attention was focused on the mysterious object orbiting the planet, the source of the energy signature that had caught their attention.

"By the Goddess," Benezia whispered, her voice tinged with a mixture of wonder and fear. "What are we looking at?"

Silence hung in the air, the crew's eyes locked on the enigmatic object as they struggled to comprehend its nature. It was unlike anything they had ever encountered before, a stark reminder of the unfathomable depths of the cosmos.

A ring-shaped object, roughly ten thousand kilometers in diameter, orbited the gas giant. Massive and imposing, the structure seemed to have landmasses on the inner surface and was dotted with lakes, oceans, and mountains. As the fleet drew closer, the sheer scope of the engineering marvel became apparent.

"A megastructure that dwarfs the Citadel itself," Nihlus remarked, his voice awestruck. "But it's not just its size that's impressive. It's the complexity of its design and the ingenuity of its construction. Whoever built this is a master of engineering on a scale we've never seen before."

"Protheans?" The aged asari suggested, her eyes never leaving the object. "Could it be their work?"

"Possible," Nihlus acknowledged. "But there's no way to know for sure until we get closer. Is there any sign of activity from the object? Any indication that it's occupied or active in any way?"

Snapping from their trance-like state, the crew quickly began to run scans, their hands flying over the controls as they worked to gather as much information as possible. The atmosphere was charged with a mixture of excitement and trepidation, the sense of discovery hanging heavily in the air.

Still frazzled, an officer spoke. "N-Nothing, Spectre. Other than the energy pulses, no emissions or signals of any kind are being broadcast. Whatever its purpose, the object doesn't seem to be in use, or at the very least, not in the manner that it was designed for."

The Matriarch's brow furrowed in thought. "Curious. It's a remarkable achievement of engineering, but it's silent and still. Why would someone build something so magnificent, only to leave it abandoned and forgotten?"

"The Citadel shared a similar fate." Nihlus pointed out. "Perhaps this is another relic of a long-lost civilization, a testament to their greatness that has outlived its creators."

Benezia nodded, her expression growing contemplative. "It's a sobering reminder of the fleeting nature of existence. No matter how grand our achievements are, in the end, we are all mortal, and the universe will continue without us. It's a humbling thought, one that we would do well to remember."

"Agreed," Nihlus murmured, his gaze still fixed on the enigmatic megastructure. "Still, it's an incredible sight. Even if it's a tomb or a monument to a vanished race, it's a testament to the power of creativity and imagination."

"In the meantime," Benezia interjected, her tone practical and businesslike. "We should focus on the task at hand. What are our scanners telling us about the object? Are there any indications of its age or origin?"

"Running a full analysis now, Matriarch." The sensor officer replied. "Results should be in momentarily. Preliminary scans indicate that the metal is made of an unknown alloy, and its age is impossible to determine at this time. The land masses inside the structure are rich with plant life, and scans have confirmed a breathable atmosphere. The temperatures appear to be suitable for organic life."

Benezia's expression turned thoughtful. "Interesting. Perhaps the structure was designed to house a population or to serve as a sanctuary of some sort. It's hard to imagine such a colossal undertaking being motivated by anything less than a pressing need."

"Or the need to show off their power and influence," Nihlus added. "Some cultures are motivated by a desire to impress and intimidate, and this could be a manifestation of that mindset. Either way, we need to proceed with caution. We don't know what dangers may lurk within, or what the creators of this object may have left behind."

"True." Benezia conceded. "But we also can't let fear and uncertainty paralyze us. We have a mission to accomplish, and the answers to our questions may lie on that structure. We need to approach it with care, but also with courage and determination."

Nihlus nodded, his eyes gleaming with resolve. "I couldn't agree more, Matriarch. We'll prepare a team and make plans for a landing party." Turning to the captain, he continued, "Keep the ship at a safe distance and maintain constant surveillance of the object. If there's any sign of danger, or if we encounter any resistance, we'll need to be ready to respond quickly and decisively."

"Understood, Spectre." the captain replied, his voice crisp and efficient. "We'll keep the engines running and the weapons primed, just in case."

Tapping her omni-tool and bringing up a display, Benezia reviewed the current roster and status of the crew. After a few moments of thought, she gave a slight nod. "I'll need to inform the council of this discovery immediately. They'll want to know what we've found, and we'll need their guidance on how to proceed. In the meantime, Nihlus you'll be in charge of assembling a ground team, and I want a mix of the finest soldiers, scientists, and engineers at our disposal."

The council Spectre nodded and glanced at the Captain. "Do you have any recommendations for the ground team, Drutus?"

As the pair of turians began to discuss possible candidates, Benezia tuned them out and made her way to the FTL comm room. "Now then, let's see what the council has to say about this."

"It's remarkable, truly remarkable." Liara breathed, her eyes wide with wonder. An image of the ring was brought up on her omni-tool. Strapped in the seat of a UT-47 drop shuttle, along with Tali, Mordin, and a handful of other personnel, the shuttle descended towards the colossal ringworld, a pair of A-61 Gunships escorting them. "To think that such a marvel of engineering could exist in our galaxy, and yet we had no idea of its presence until now. It's a humbling thought, isn't it?"

Focused on the image being projected, Tali blinked. "I-I can't believe what I'm seeing. Keelah, the size of that thing. How is it even possible to construct something so massive? It must have taken an incredible amount of resources and manpower to build. It's incredible!"

"Indeed," Mordin agreed, his tone brisk and matter-of-fact. "An impressive feat of engineering, to be sure. Materials and techniques required to construct such a structure likely beyond anything we have encountered before. Will be interesting to study its composition and design in greater detail, once we have a chance to examine it up close."

As the shuttle breached the upper layers of the atmosphere, the view outside the windows was breathtaking. The vast, curving horizon of the ring stretched out before them, its surface a patchwork of mountains, valleys, and oceans. The sight was awe-inspiring, and the crew found themselves speechless, their eyes glued to the spectacle unfolding before them.

"Approaching the LZ." the pilot's voice crackled over the comm. "Touchdown in T-minus 3 minutes." The passengers in the shuttle exchanged glances, the gravity of their situation settling in. They were about to land on an alien megastructure, an engineering marvel that defied explanation. The thrill of the unknown was palpable, and they steeled themselves for the adventure that awaited them on the surface of the ring.

Touching down first, the pair of gunships had landed on either side of the UT-47. With their ramps lowered, eight armed guards emerged from the smaller ships, four per gunship. Helmets on and weapons at the ready, they fanned out and formed a perimeter, securing the area.

Garrus and Wrex were among the squads, their eyes scanning the surrounding area for any signs of trouble. The landscape was lush and vibrant, a striking contrast to the sterile confines of the ship. Trees and plants of every shape and color lined the area, their leaves rustling gently in the wind. The sky above was a brilliant shade of blue, dotted with wispy white clouds, and the air was warm and fragrant with the scent of flowers.

"All clear, Sir," one of the guards called out, his voice echoing across the open space. "No signs of hostiles or anything unusual."

"Roger that," came the reply from the gunship. "Maintain perimeter and watch for any movement. Squad two, advance to the shuttle and escort the ground team."

As the second squad of guards moved to surround the shuttle, the ramp of the craft lowered, and the science team stepped out onto the grassy plain. They were a diverse group, representing a range of species and disciplines. There were scientists, engineers, and a few combat-ready specialists, all eager to explore the mysterious ring and uncover its secrets.

Nihlus was at the front of the group, his keen eyes scanning the surroundings for any sign of danger. "What are our scanners picking up?" he asked, his voice low and urgent. "Any energy signatures or anomalous readings?"

Tapping his omni-tool and reviewing the information that was displayed, Mordin shook his head. "Air is breathable, no harmful pathogens or bacteria. Local plant and animal life are abundant, but scans have not detected any sentient lifeforms. Still, scans could be wrong. Best to exercise caution, and refrain from eating or drinking anything local." Putting away his omni-tool, the salarian took a moment to take in the scenery. Before removing his helmet, taking a deep breath of the fresh air, and letting out a content sigh. "However, will repeat, air is breathable, not harmful. Safe to remove helmets, in case of emergency, put back on, and follow standard procedure."

Following the doctor's example, the others followed suit. Taking a deep breath of the fresh air, Liara couldn't help but marvel at the beauty of their surroundings. "It's incredible," she breathed, her eyes shining with excitement. "I've never seen anything like this before. It's like a paradise, untouched by time or civilization."

Unknown Avian creatures flew through the air, chirping and squawking in a melodic chorus, their feathers gleaming in the sunlight. The team's eyes widened in amazement at the sight of the animals, and a feeling of wonder and reverence washed over them.

"Place is a treasure trove of biological and ecological diversity," Mordin observed, his tone betraying his awe. "Flora and fauna here unlike anything we've encountered. A veritable feast for the senses, perfect opportunity to study unique adaptations that have evolved in this environment."

Even Wrex couldn't help but appreciate the beauty and majesty of their surroundings. The old Krogan's expression softened, and a rare smile tugged at the corners of his mouth. "It's not a bad spot," he admitted, his voice uncharacteristically gentle.

The others exchanged amused looks, surprised to see the gruff Krogan showing a softer side. Resting his assault rifle against his shoulder, Garrus' mandibles flared in a smirk. This place was something else, and the potential for discovery was limitless. He couldn't wait to start exploring and uncovering the mysteries that lay hidden within the ring.
