On Planet Abel, the line between human and robot has blurred into irrelevance. Apollo is a robot indistinguishable from any person. Mikaru is human but built to resemble synthetic life. Their ordinary coexistence shatters when a cloaked intruder smuggles something dangerous aboard a transport vessel: a memory chip running Cipher, an OS with the power to rewrite identity itself. Apollo pockets the chip on impulse, treating it like a curiosity. Within hours, he's unraveling. His behavior becomes erratic, his motivations murky. Mikaru watches her partner deteriorate and realizes the chip isn't just corrupting Apollo's systems. It's rewriting who he is, peeling back layers of memory and purpose neither of them understood existed. What Cipher actually does, what it truly contains, and why someone would risk everything to smuggle it into their world becomes the question that forces Apollo and Mikaru backward through decades of concealed history. The answers reshape everything they believed about their planet, their existence, and what it means to be alive at all.
