A third timeline does reconcile the fact that Ganondorf rather blatantly dies at the end of Twilight Princess. My reconciliation of this was that Angahim revived Ganon specifically rather than Ganondorf in LttP (or Angahim *was* Ganon, i forget, but a reincarnation sort of deal), to speak something to the point that Ganondorf lost his humanity at that point
The three way split was theorized by some, but the two-point one was pretty functional barring the discrepancy i addressed

Monster Hunter: pissing me off since 2010.
