What If The Institute Was Never Destroyed | Fallout

What if the Sole Survivor never betrayed the Institute? This is the counterfactual history of a Commonwealth where the loyalty test in Father's quarters goes the other way, where the coalition's one chance to destroy the Institute dies unspent, and the organization survives to rule the wasteland from the shadows for sixty years. It follows the fall of the Prydwen, the slow strangling of the Railroad, a doomed second uprising a generation later, and the quiet, permanent suspicion that settles over every Commonwealth settlement once nobody can be sure their neighbor is still their neighbor. No victors, no clean ending, just the long cost of one choice made in a sealed room underground.
