Trope-a-Day: The Chosen One
The Chosen One: Again per Because Destiny Says So, the people whose timelines are meddled in by the local weakly godlike superintelligences on the grounds that their existence, or something they will do during their existence, is necessary to their designed Optimal Future.
Somewhat subverted inasmuch as what the Chosen One eventually does may be something whose significance is completely incomprehensible to anyone without the acausal-logic-enabled quasi-omniscient viewpoint of a weakly godlike superintelligence, and may even be little more than happening to be the right butterfly in a chaos cascade.
