In a world where innovation is currency and intellectual property is power, Arthur Finch, a once-promising but now bankrupt inventor, finds himself at rock bottom. Desperate for a fresh start, he attends a liquidation auction of forgotten patents, hoping to salvage a glimmer of his former ambition.

Among the thousands of dusty, discarded designs, he acquired a portfolio containing a schematic for something truly impossible: a device dubbed the 'Chronos Engine.' Initially dismissed as theoretical nonsense, Arthur's tinkering reveals the Chronos Engine's terrifying truth: it doesn't just observe causality; it subtly influences it within a small, localized field. It can shift probabilities, nudge events, and even create minor, undetectable paradoxes that rewrite moments of the immediate past.

A dropped key suddenly appears in his hand. A missed lottery number becomes a winning one. A critical mistake in his past is subtly erased. But these seemingly innocuous alterations have unforeseen, catastrophic ripple effects. The world around Arthur begins to subtly destabilize.
