this is just a random thought.. but has anyone ever noticed how the temple of time from TP looks similar to the ToT from OoT?(and in TP i mean the outside part you enter with the 2 guardian statues after beating the skull kid) other than the staircase, the guardian statues and the stairs in the tunnel in TP, they look very similar to each other. since TP apparently comes after the adult timeline, then after castle town in OoT was rebuilt after ganondorf's death then the new citizens could have made some minor changes to the temple of time. the floor was dug into and made deeper, the hallway to the MS had stairs put into it, windows were added to the sides, where the MS actually is, is still a circular room with the sword in the middle, and the statues could have been made using some sort of magic to protect the MS from those who arent the Hero of Time. then within a possible 100-year difference between games in the adult timeline, the OoT castle town/market was eventually destroyed by massive plant overgrowth which could explain the ruined look the temple has in TP, though that does not explain what happened to ther est of the city. although, i do find one thing wrong with this though, and that is if TP comes after the OoT adult timeline, then link never put the MS back into the pedestal. if he did, then TP would be after the child timeline, and so after MM. but that timeline spans off into WW(if i remember correctly).
anyway, if link did NOT put the master sword back, then how did it get back into the pedestal for TP link to find? other than that question, some others i myself will think of, and some otehrs you will think of... i'd say that the two temples are closely related. of course, this was only based off of the odd look around the OoT temple of time on my Project64 emulator and basically just taking notice of some things around me when going through to the MS on TP, then finally considering the possible origin of the TP ToT.
note: i am aware that some words/phrases have been repeated several times so you dont have to point that out.
