This is not just a story about time travel.

It is a sandbox of the entire world.

Any time. Any place. Any turning point. Open.

Enter ancient Rome and move an empire. Stand at Versailles and rewrite a treaty. Break trade routes. Unmake revolutions. Sit across from Leonardo da Vinci before he sketches his next machine. Change a single sentence last week and let the world reorganize around it.

There are no scripted outcomes. Every action compounds forward.

When you return to the present, everything is recalculated around what you touched. Technology shifts. Economies restructure. Borders harden or dissolve.

Megan Cole, your ex-wife, still exists. Your history with her may not.

The Butterfly Code is a causality engine disguised as a roleplay.

Choose a year. Choose a place. Then see what survives.
