Concurrent Pre-Story Adaptations
For adaptations set after the core narrative, see Experimental adaptations. For the primary timeline, see Adaptations by medium. For contradiction between pre-stories, see Adaptation and impossibility.
Concurrent Pre-Story Adaptations categorizes works situated before, during, or alongside the events of the core story, but from perspectives marginal or wholly absent in the novel.
Works in this category include: separate origin stories for Katita and Leif; accounts of the conflict that injured Leif; Katita's medical training and triage apprenticeship; cycles that allegedly preceded the documented loop; parallel versions of the same two days experienced from other viewpoints—the activists' timeline, the mechanic's internal monologue, the McRaes' escape plan.
Crucial distinction from Experimental Adaptations: pre-story works accept the glitch as permanent structure and propose no resolution. They instead ask: what was the world before this impossible loop began? Some answer: there was no before. Others: the before is just the after observed in reverse. Many remain deliberately unresolved. [citation needed]
