I also want to throw in my headfanon time. I'm not the first to make it, as it's practically darklink01's/Voo_Bopo's/talonmalon333's/mαrkαsscoρ's Mixed/Balanced Split Timeline.
Adult: SS - OoT - WW/PH - ST - TMC - FS - FSA - TFH
Child: SS - OoT/MM - TP - ALttP/OoX/LA - ALBW - TLoZ/TAoL - BotW
- TMC takes place after the Great Deku Tree's plan to connect the islands is fulfilled and the rest of the FSS follows (the ancient language from WW's intro also appears to have a resurgence in the Ocean King's world and in New Hyrule, so it continues in the FSS)
- Force Gems from PH and ST continue in TMC (light force) and FSA; Triforce is never mentioned
- WW's Ganon is Triforce wished away, so he can't resurrect. FSA's Ganon is more Demise's hatred.
- TP Ganondorf is resurrected between TP and ALttP, similar to how he comes back between ALttP and ALBW or before, TLoZ
- The OoX games can be moved between ALBW and TLoZ as well, but I prefer OoX Link as being the same as ALttP and LA Link and that this same Link is Gramps in ALBW. The Master Sword that Gramps has can be the one from OoX, and ALBW's backstory can be another adventure of ALttP Link after LA (where Ganon comes back but is sealed instead of killed).
- TFH is on the Adult line for the 4th Purple Link and Linebeck reference, but it uses ALBW's language, so maybe it just coincidentally happens to be the same after a long time after FSA? The Fierce Deity is referenced too so that line can have its own Termina. I don't really care much for its placement.
Keeping the Four Sword solely after the Master Sword's drowning streamlines the timeline since we don't have to switch around which magic sword to use, IMO. Also, with the hero of man (previous hero) shown to not wear a cap, and with TMC Link getting a cap, it was implied to be the first time where a hero started the hat tradition. Then Skyward Sword ruined that idea. But, in ST, the soldiers wear the traditional green tunic, no cap. Link from TMC can be seen as following that trend.
Also, I like that it's almost balanced. I find it more aesthetically pleasing then many ECT or EAT theories where one side has significantly more than the other.
I didn't think there would be much of a difference if the FSS happened in New Hyrule, but then I remembered that the Gorons seemed to be in an early state of development in TMC when they had a village in ST already. Maybe New Hyrule is this line's version of Greater Hyrule or something. Other races like Gerudo could have just gone to new lands (like in OoX) or lived on boats (like the Gorons in WW) so that's my cop-out for other races coming back as well. I don't think this is strong evidence, but FSA's map art shows Hyrule depicted as one of a couple islands (probably from WW influence as it was the game released before this one). I'm also headfanoning that FS's map fits on this map, but both of these are honestly oddballs. Geography and Zelda theories don't go that good together.
So what do you guys think? It was already posted here by mαrkαsscoρ, but I wanted to throw in all my other thoughts/reasoning.
