CHTHON

2030. Ukraine is in NATO, and the front has frozen into history's most-watched stalemate. Every trench, every truck, every soldier visible from space. Nothing moves. No one wins.

So Russia goes where no satellite can see. Down. Beneath the border, an army of three hundred thousand waits in the dark for the order to surface behind NATO's line.

Ukraine's answer is already in the rock. A nuclear-armed tunneling drone swims through the deep earth at walking pace, sealing its passage behind it, bound for a fault line beneath the buried army. It cannot be seen. It cannot be stopped. It cannot be recalled.

It can only be heard. And one man in Russia knows that a source does not move.

The operator. The hunter. The diplomat. Three people who will never meet, one machine none of them can call back. And buried in an appendix nobody read, a fault that runs the other way. Toward home.

The earth keeps no one's secrets.
