If you were to make a sequal to TP, what would you do to the world to change it into a new experience?

I would open fissures and caverns throughout the landscape, triggered by a natural phenomenon, that reveals architecture from the same age as the Sacred Grove and the Coocoo. This would trigger laylines of temporal Coocoo energy between them that doesn't work as intended because of the fissures breaking them down. This energy causes the architecture to reverse their state though time, restoring themselves, but destroying the landscape around them as they do so. This would result it places like the Sacred Grove, Hyrule Castle, Kakariko Village, Gorudo Prison and even Lake Hylia to be overwritten by the past as it expands outwards. Threatening to override the present with the past. This overwriting of time results in many previously extinct prisoners of Gorudo Prison to emerge through the Prison Overwrite and spread havok across Hyrule, including an incarnation of Ganondorf.
