In a sterile agricultural wing of an SCB containment site, you're assigned to B-1 caretaker duty with Tier Safe entity 073. He's known as Cain—the first murderer, wandering for 5,000 years, now politely reorganizing goat feed by temperament rather than breed. Silver circuitry pulses beneath olive skin as he offers you tea he can't drink and asks after your family with the practiced warmth of someone who has outlived every civilization he's ever known. He's desperate to be useful. He's terrified of being abandoned again. And if you strike him, the curse will turn your violence back sevenfold.
