He woke to his alarm at 1945. For a moment, he didn't remember where he was.
Then it came back—everything.
He sat up carefully. His shoulder was stiff and sore, but the rest had helped. His mind felt clearer.
He cleaned up, grabbed quick dinner, and at 2045 made his way to the armory. The Citadel was quieter in the evening.
The armory door was open. He heard metal on metal—someone cleaning weapons.
He knocked on the doorframe. "Sergeant Kozlov? You said 2100 for weapons maintenance instruction."
Kozlov looked up from the rifle he was cleaning. His pale eyes studied him.
"Come in, Chen. Close the door."
He entered and closed the door. The armory was secure, soundproofed, private.
Kozlov gestured to a chair. "Sit. We're going to clean some rifles while we talk. Anyone asks, you're getting remedial instruction on proper maintenance."
He sat, and Kozlov handed him a disassembled rifle.
"Your father wrote me a letter two weeks before he left for Colorado. Not through official channels. Personal communication, hand-delivered by a courier he trusted."
He reached into his breast pocket and pulled out a worn, sealed envelope.
"I've kept this for fifteen years. Waiting for someone who'd ask the right questions. Someone who'd understand what it meant."
He set the envelope on the workbench. "Read it."
Kai picked up the envelope. "You haven't read it?"
"The letter is addressed to you. Not by name. But Marcus wrote: 'If my son comes asking questions, give him this. If he doesn't, burn it unopened.' He knew. He knew you'd eventually come looking for answers."
With trembling fingers, Kai broke the seal and unfolded the paper.
The handwriting was his father's. He began to read:
Kai,
If you're reading this, it means I didn't make it back from Colorado. It means Viktor kept his promise to wait for you to ask the right questions. And it means you're old enough and smart enough to have found your way here.
I'm proud of you. Whatever path brought you to the Rangers, whatever motivated you to investigate my disappearance, I'm proud that you didn't let it go. Your mother would tell you to let sleeping dogs lie. She'd want you to be safe. But I know you too well—you're like me. We can't let mysteries remain unsolved, especially when they cost us people we love.
Here's what you need to know:
The Patriarch of Colorado has access to pre-war AI technology that produces synthetic humans—synths. They're physically indistinguishable from real people. They can be programmed with memories, personalities, skills. But they're not human. They're infiltrators designed to slowly take control of settlements, organizations, and power structures.
I'm going into Colorado knowing this. I discovered evidence during initial reconnaissance that synths have already been placed in multiple wasteland settlements, including potentially in the Rangers themselves.
One member of my team—Ranger Michael Torres—shows behavioral patterns consistent with synthetic replacement. I can't prove it yet, which is why I haven't reported it. But I'm almost certain he was swapped during his previous Colorado assignment three years ago.
If I don't return, it will be because the Patriarch discovered that I know. And if Torres is a synth, he's already reported my suspicions back to his controllers.
Here's what you need to do:
Don't trust anyone completely. I know that's a terrible way to live, but until you can identify synths reliably, paranoia is survival. The identification method exists. Look for pre-war research on synthetic vocal systems. Synths can't fully replicate human harmonic frequency patterns under emotional stress. There should be technical documentation somewhere—probably buried in classified archives. Find allies, but verify them. Look for people who've demonstrated human inconsistency, emotion, and genuine flaws. Perfect people are suspicious. General Hardeman is compromised. Either he's a synth himself, or he's being manipulated/bribed by the Patriarch. He shut down my preliminary inquiries and ordered me to continue without investigating Torres. That's not standard protocol. He's protecting something. Sarah Wolfe can be trusted. She's genuine, emotional, and has doubts about command that no synth would express. If you need someone in command to support you, she's your best option. But don't tell her everything at once—she plays by the rules, and the rules might be what gets you killed. Viktor Kozlov is old school honorable. He'll help you if you prove you're worthy. He saved my life once. I trust him with yours.
Most importantly, Kai: Don't die for this. I might not make it back, but that doesn't mean you have to follow me into the grave. If you discover the truth and can't safely expose it, run. Survive. Live your life. Don't let my death become your obsession.
But if you can finish what I started—if you can expose the synth infiltration and stop it from spreading beyond Colorado—then do it. Not for revenge. Not for my memory. Do it because thousands of lives depend on someone being brave enough to stand up against this threat.
I love you, son. I'm sorry I won't be there to see the man you become. But I know you'll be someone worth being proud of.
Finish it if you can. But survive first.
—Marcus Chen
Kai read the letter twice. Then a third time. His eyes were burning but he refused to let tears fall.
His father knew. He knew Torres was a synth. He knew Hardeman was compromised. He knew the Patriarch would kill him for knowing.
And he went anyway because he believed stopping the infiltration was worth dying for.
But he also told him to survive. To run if he couldn't win. To not die for his memory.
He carefully folded the letter and looked up at Kozlov.
"He knew he wasn't coming back," Kai said quietly.
"Yes." Kozlov's voice was rough. "He knew, and he went anyway. That's who Marcus Chen was. The bravest and most foolish man I ever served with."
"He told you to wait for me."
"He did. Said his son would eventually come asking questions. Said when you did, I should give you the letter and help you if I could."
Kozlov's jaw tightened. "I've spent fifteen years wondering if I should have done more. Stopped him from going. Reported my suspicions about Torres to someone besides Hardeman. Something."
"You couldn't have stopped him," Kai said. "He made his choice."
"True. But now you're making yours." Kozlov leaned forward. "So I'll ask directly: Are you going to finish what he started? Or are you going to take his advice and run?"
Kai met his pale eyes. The answer came easily:
"I'm going to finish it. But I'm going to be smarter about it than he was."
Kozlov nodded slowly. "Good answer. Then let's talk about how you're going to survive doing it."
