Well, people say the timeline starts with ZSS, but ignoreing that, it is MC. Which is a 2D with gorons. After that is OoT, which has gorons. In timeline A, MM and TP has gorons. In ALttP, there is no gorons which confuses many because the next game, OoA/OoS does. On timeline B, TWW, PH, and ST do have gorons. In ZSS, MC, and OoT, there are Dekus. In in MM, there are. There are no dekus in later games because of what Kaepora Gebora told us about the Dekus doom. We do not know if ZSS has zoras. MC does not, OoT does. Which I assume they started evolving into that then. In MM, there are zoras. In TP, ALttP, and OoX, there are zoras. But in ALttP, they evolved into river zoras and back into sea zoras in OoX. In timeline B, TWW has a lone zora. The rest evolved into ritos and stayed in the Old Hyrule. PH takes place in world of the ocean king. ST takes place in New Hyrule. Both of which are not Old Hyrule, which they would not leave because Valoo is in Old Hyrule. Again, I do not beleive in split timelines.
