Constantine adjusted his calculations. No relief. No cavalry. Three teams of first-year cadets and forty-two thousand simulated lives.

  "Then let’s give the station personnel time to seal the bunkers and make the Veth’kai work for it." He highlighted positions on the shared display. "Elena, your team handles primary evacuation coordination. Sebastien, your team takes spaceport defence. I’ll lead the mobile reserve and buy you more time at the research stations."

  "That’s suicide," Sebastien said. "You’ll be overrun in the first engagement."

  "Probably. But it gives the station personnel time to reach their bunkers, and it might draw Veth’kai forces away from the main settlement."

  "You’re wasting military resources we need for the primary defence."

  "It’s my call. I’m making it."

  Constantine’s mobile reserve reached the first research station eighteen minutes before the Veth’kai. He positioned his forces in a defensive arc along a ridgeline overlooking the approach vector, knowing they couldn’t hold long but wanting every advantage the terrain could give.

  "Station personnel are evacuating to bunkers now," Valentine reported from the left flank. "Estimate twelve minutes until sealed."

  Twelve minutes. Enemy icons advanced on his display. He calculated their speed against his available firepower and didn’t like the answer. They’d be lucky to hold for eight.

  "All units, concentrate fire on the lead elements. Let the flanks go. I want their vanguard bleeding before they reach effective range."

  The first Veth’kai wave hit the ridgeline six minutes later. The simulation rendered them as angular, insectoid raiders in powered armour. Constantine’s people cut down the first rush, repositioned, cut down the second. The third rush got close enough for the simulation to register hand-to-hand combat. Two of his team went down.

  Behind him, the bunker status indicators ticked upward. Sixty percent sealed. Seventy. Eighty.

  "Fall back to secondary positions. Keep firing."

  They gave ground in good order, trading metres for minutes. At eleven minutes the bunker indicators went green. Sealed. Two thousand people underground, protected by reinforced walls designed to survive orbital bombardment. The Veth’kai could dig them out, but it would take days and cost them forces they’d rather spend elsewhere.

  Constantine pulled his surviving people out and ran for the second station.

  The second station fell faster, his depleted forces unable to mount the same defence. But the personnel there had watched the first station on their feeds and started evacuating early. Most reached the bunkers before the Veth’kai arrived. Constantine lost three more people buying the last stragglers time to get underground.

  The third station was too far. By the time his remaining forces reached visual range, the Veth’kai had already begun their assault. Constantine could see the station burning on his tactical display, personnel icons winking out one by one.

  He made the call to bypass. Preserve what remained of his mobile reserve for the spaceport.

  Three months ago, that decision would have paralysed him. Today it took four seconds. Each one felt like an eternity, and he made the call anyway.

  The final phase brought all three teams together at the spaceport. Sebastien’s defensive positions held better than expected. He’d layered his defences three deep, with fallback positions pre-calculated and supply caches at each point. Textbook work, and effective. Elena’s evacuation coordination was flawless, transport ships launching in precise intervals that maximised capacity while minimising exposure to enemy fire. She moved twenty-eight thousand people through a spaceport designed for half that throughput and made it look routine.

  Constantine’s battered mobile reserve plugged gaps in the perimeter. When the Veth’kai broke through Sebastien’s outer defensive ring on the eastern approach, Constantine’s people were there. When a second breakthrough threatened the landing pads, they were there too. They fought with the desperate effectiveness of soldiers who’d already made peace with not all going home.

  The scenario ended with twenty-six thousand colonists evacuated. Sixteen thousand dead or captured, including the entire population of the third research station.

  "Results," Grimm said. "Team Gamma achieved highest evacuation efficiency. Team Beta maintained defensive integrity longest. Team Alpha bought six extra minutes for bunker seals at the first two stations, potentially saving an additional four thousand lives if relief ever arrives."

  He looked at Constantine.

  "Ramsey. Your decision to split forces and defend the research stations was questionable."

  "Yes, sir."

  "It was also morally correct. Those bunkers might hold. Those people might survive. You gave them a chance when the correct strategy said to abandon them."

  Grimm’s expression didn’t soften. He cleared his throat.

  "The Academy teaches you to make hard choices. Sometimes the hardest choice is accepting that you can’t save everyone while still trying to save as many as possible."

  He turned to address the room. "Debrief in ten minutes."

  The debrief lasted two minutes before it became an argument.

  "You risked the entire operation for a handful of research personnel," Sebastien said. His voice was controlled, but his jaw was tight. "If your mobile reserve had been destroyed earlier, we couldn’t have plugged the gaps at the spaceport. The evacuation numbers would have been worse."

  "But they weren’t destroyed earlier," Constantine said. "And those research personnel aren’t just numbers."

  "People are acceptable losses when species survival is at stake."

  "Be careful with that philosophy. The ends can’t always justify the means."

  Sebastien stepped closer. "That philosophy is how Man survives."

  "Does it? Because from where I’m standing, it looks like a philosophy that loses everything worth fighting for."

  "Boys." Elena’s voice cut between them. "The scenario is over. Save the philosophical debates for the cafeteria."

  Sebastien wasn’t finished. "You got lucky, Ramsey. Your sentimentality could have cost thousands more lives. Next time it might."

  "I saved four thousand people who would have died under your strategy." Constantine kept his voice level, though the heat was climbing in his chest. "Maybe that’s not efficient enough for you. But those four thousand are alive because I made a choice you wouldn’t have."

  "You don’t know what choices I would have made."

  "You said it yourself. Concentrate defensive assets. Everything else is expendable. Your words, Sebastien. Not mine."

  "Context matters. Those were opening recommendations based on available intelligence. I would have adjusted as the situation developed."

  "Would you? Because every adjustment you made went the same direction. Tighter perimeters. More concentrated force. Smaller circles of protection. At what point do you stop shrinking the circle and start asking whether anyone outside it matters?"

  Sebastien’s eyes went hard. Something in the last line had landed harder than Constantine intended. Elias, standing near the door, shifted his weight.

  They were close now. The pulse in Sebastien’s throat was visible.

  "That’s enough." Grimm’s voice cracked across the room. Both cadets froze. "Cabot-Winthrop. Ramsey. Separate study halls. Cool down. And remember that the enemy is out there, not in this room."

  Constantine forced himself to step back. Sebastien held his gaze for a long moment, then turned and walked out without a word.

  Elena appeared at Constantine’s side as the other cadets filed out.

  "That was intense."

  "He’s wrong."

  "Not entirely. And neither are you entirely right." Her gaze followed Sebastien down the corridor. "That’s what makes this hard."

  They walked in silence for a few paces. Then Elena said, "The scenario was based on an actual colony layout. Did you notice?"

  "Colony Meridian. Settled eighteen years ago. Current population forty thousand."

  "They’re teaching us to defend specific places."

  "Because they expect us to have to defend them."

  Elena didn’t answer. She didn’t need to.

  They parted at the corridor junction. Elena had Cascade Drive Theory. Constantine had his mandated separate study hall. Two hours alone with his thoughts and a tactical review he was supposed to write.

  He wrote the review. Dry, factual, analytical. Timeline of decisions, force dispositions, casualty projections versus actual outcomes.

  Grimm’s response came back within the hour. One line: Noted. Your tactical writing is improving faster than your tactical patience. Both need work.

  That evening in the mess hall, Sebastien sat three tables away with Elias and didn’t look in Constantine’s direction. Constantine didn’t look in his. Elena sat between them, eating with the unconcerned focus she brought to everything, and said nothing about any of it.

  Constantine thought about Grimm’s opening statement. Cadets with whom you’ve walked these halls. Not long ago those fourth-years had been legends, polished and confident, destined for the best assignments. Now some were risking their lives on frontier worlds most first-years couldn’t find on a star chart. Harrison was one of them. Constantine hadn’t heard anything, which could mean his mentor was fine or could mean the opposite. The Academy didn’t keep its cadets informed about the fate of its graduates. You found out when the memorial service announcements went up on the board, or you didn’t find out at all.

  In three years, it would be his turn. And Sebastien’s. And Elena’s. The argument in the training facility wasn’t just about a simulation. It was about what kind of officers they intended to become when the decisions were no longer theoretical and the lives being lost were real.

  Sebastien would make the most rational choice every time and sleep soundly. Constantine felt the need to fight for every life he could reach. Elena would somehow find an approach that worked when neither pure strategy nor pure compassion would, because Elena kept finding options he couldn’t see yet.

  He wondered which approach the frontier would reward, and which it would punish. He was beginning to suspect the answer was all three, depending on the day and the enemy and the particulars of the situation at hand.

  Chapter 11: EMPTY CHAIRS

  The Alien Cultures classroom felt different without the fourth-years filling the back rows. Constantine took his usual seat near the middle. Elena settled into the chair beside his. The empty spaces made the room look almost like a mouth missing its back teeth.

  Professor Vega was otherwise occupied, leaving Arwen Versperlyn to conduct the class alone. The Kaelori stood at the front of the room, her platinum hair catching the artificial light in ways that shouldn’t have been possible, those luminous violet-blue eyes sweeping across the assembled cadets.

  "Today we will discuss genetic compatibility," Arwen announced. "A topic of particular relevance given the Academy’s recent assessment notifications."

  Elena stiffened beside him. The compatibility results were supposed to be posted tomorrow. The entire first-year class had been buzzing about it for days.

  "My people resolved the question of compatibility three thousand years ago." Arwen paced the front of the room with the fluid grace that always made Constantine think of water finding its level. "We engineer our pairings. Emotional attraction is calibrated to align with genetic optimality. The result is efficient reproduction, strong pair-bondings, and minimal social friction."

  Valentine raised his hand. "So Kaelori don’t ever fall in love with the wrong person?"

  "We do not fall in love at all, in the sense your species defines it." Arwen’s features arranged themselves into something like scholarly interest. "We experience true pair-bonding. We feel deep attachments. But these feelings are designed to emerge only with a partner who is genetically appropriate."

  "That sounds horrifying," Jenna Park said from two rows back.

  "Does it? Your species frequently experiences tremendous suffering from mismatched affections. Relationships fail. Resources are wasted. Children are abandoned. Some of your greatest tragedies are founded on the inefficiency of leaving pair-bonding to chance and hormones."

  "You eliminated personal choice," Constantine said.

  Arwen’s eyes fixed on him. "Did we? Or did we intentionally align our choices with the benefit of our kind?" She stepped closer, her movement creating a subtle disturbance in the air. "Your species chooses partners based on short-lived chemical responses, social conditioning, and physical attributes. These factors correlate poorly with long-term compatibility, and with the exception of the latter, genetic fitness."

  "We also choose based on shared values. Character. Who someone actually is."

  "How fascinating. And yet your Academy has just completed genetic compatibility assessments on every first-year cadet. Your own institutions readily acknowledge that genetics are an important factor in pairing decisions, a factor that matters to the species."

  "Acknowledging something matters isn’t the same as letting it determine everything."

  "No. But it does suggest your species is somewhat less committed to romantic freedom than your rhetoric suggests."

  Elena’s voice cut through the exchange. "The assessments are informational. Not mandatory."

  Arwen turned toward her. "Are they? I have observed your Academy’s culture rather closely, Cadet Sørensen. Cadets who accept high-compatibility matches tend to receive preferential treatment. Mutual career advancement, joint-posting assignments, various incentives to have more children than the norm. The system incentivises compliance without requiring it."

  "That’s not the same as literally engineering our emotions!"

  "No. It is merely engineering your circumstances until your emotions follow." Arwen’s slight smile held no warmth. "My people are honest about our approach. Yours attempts to achieve a similar outcome while maintaining an illusion of free will."

  Elena’s composure developed a hairline crack. Her jaw tightened. "You speak as if you understand human relationships. But you’ve already admitted Kaelori don’t experience love the way we do. How can you evaluate something you’ve never felt?"

  "In the same way I evaluate everything. I draw conclusions based on observable evidence rather than personal experience." Arwen’s violet-blue eyes held Elena’s green ones. "Perhaps my approach gives me clarity you lack."

  "Or perhaps it gives you blind spots you can’t even recognise."

  The tension fairly crackled. The class was dead silent. Constantine leaned forward, hoping someone would say something to break it.

  Arwen turned back to the class. "Consider this scenario. Two cadets discover they have highly compatible genetics. Their potential offspring would represent optimal profiles. However, one of these cadets has developed feelings for a third party, with whom her compatibility is suboptimal." A pause. A glance toward Elena. "What should those cadets do? Follow genetic science, or their own preferences?"

  "People aren’t breeding stock," Thomas said.

  "The Mandate rather strongly suggests otherwise." Arwen’s tone stayed neutral. "Your entire civilisational structure is built on the fragilities of the human genome. Tens of millions of lives are knowingly sacrificed to its interests. Natural selection is artificially applied at species scale. The underlying philosophy clearly regards genetic fitness as paramount."

  "The Mandate is about preventing extinction," Constantine said. "Not turning people into commodities."

  "Is there a meaningful distinction?" Arwen fixed her attention on him. "A statistically significant portion of your class has already been removed from the Academy because their capabilities were deemed insufficient. Everything about this institution demonstrates that the individual is valued in terms of genetic contribution."

  She nodded to Elena. "Or, of course, hers."

  "We value character too." Constantine could hear the outrage in Elena’s voice. "Leadership. Intelligence. Moral courage."

  "Traits that are substantially heritable." Arwen’s smile widened slightly. "Your species pretends genetic determinism and personal achievement are unrelated. In truth, they are deeply intertwined. The character you develop emerges from the genetic foundation you inherit."

  "That’s reductive. Genetics provide potential. What we do with potential is our choice."

  "A choice substantially shaped by genetic predispositions toward certain behaviours, certain capabilities, certain limitations." Arwen seemed genuinely puzzled by Elena’s emotion. "Why do these observations trouble you so much, Cadet Sørensen?"

  "Because they’re used to justify treating people as means rather than ends!"

  "And yet you defend an institution whose sole purpose is precisely that. How fascinating."

  Constantine stood. "I think we’re getting off topic. Weren’t we supposed to discuss alien approaches to genetic compatibility rather than a critique of human institutions?"

  Arwen’s attention shifted to him, and something flickered in those ancient eyes. "You are protective of her. Interesting. Elevated heart rate, pupil dilation, subtle postural shifts to place yourself between her and a perceived threat."

  Heat rose in Constantine’s face. "That’s not relevant."

  "It is precisely relevant to our discussion." Arwen stepped closer, with the frank disregard for personal space that seemed characteristic of her species. "You and Cadet Sørensen exhibit numerous indicators of developing pair-bonding. Based on your behavioural patterns over the past several months, I would estimate you are highly compatible."

  "You can’t know that from observation alone."

  "I can estimate with eighty-three percent confidence. Kaelori sensory capabilities exceed human norms substantially. I perceive pheromone signatures, micro-expressions, autonomic responses your species cannot consciously detect." Her violet-blue eyes held his. "The compatibility between you is obvious."

  Elena had moved to stand beside Constantine, her shoulder brushing his arm. "Even if that’s true, it doesn’t give you the right to discuss our personal lives in front of the entire class."
