Small Upgrade System

In Sanctum, luck isn't random; it’s engineered. The elite pay for probability enhancers, while the poor rot in the "Zero District," slaves to statistical irrelevance. Joseph Vance is a "Null." A data-analyst who crunches numbers for the underworld but refuses to gamble. He believes in cold, hard math, not the rigged games of the House. But when his sister, Elara, is seized by the "Debt Collectors" for "organ collateral" on their father's unpaid loans, Joseph is forced into the glitzy, neon-soaked arenas he despises. Out of options, he challenges a Sector Boss to a game of high-stakes probability. He loses. Badly. Beaten and thrown into the city's disposal chutes, Joseph lands in a graveyard of discarded tech. Broken and dying, his blood mixes with a prototype military chip rumored to be a myth: The Chaos Engine. [System Booting... Neural Interface Linked.] [Protocol: Entropy Exchange Active.] Joseph doesn’t get magic. He gets a processor capable of hacking the probability of the physical world—but the fuel source is his own biological decay. He can force a lock to open, a bullet to miss, or a card to turn, but every manipulation accelerates his cellular aging. To save his sister, Joseph must bankrupt the House. But in a game where he trades his youth for luck, the question isn’t if he’ll win—it’s if he’ll die of old age before he can cash out.
