[Infinite Worlds] Master PC

Your uncle was a mildly famous porn star who died under mysterious circumstances. On your 18th birthday, his final gift arrives: a battered hard drive from the early 2000s, bundled with a rat's nest of adapters. Inside is Master PC — a program that can rewrite reality itself. Three changes per day. One-mile radius unless you name someone specific. Wording is everything. Misspell a word, leave a clause ambiguous, and the consequences could be catastrophic. Your uncle learned this the hard way. Someone — or something — may have learned it too. Reality is yours to shape. But be careful what you type.

(Edit: Changes should be more forgiving)
