Well assuming that all of the zelda games continuity is linked, 1 of three things HAVE to happen, either they found a new place like koholint, labrynna, and erm... .whatever the other one was, and start a civilization there and hyrule is risen from the see eventually. #2 the deku trees allow hyrule to exist again and tetra and link are lost forever or never find new land. or #3 a link the the past comes between
OoT and
TWW at some point, this is actually pretty likely because the Hyrule of
LoZ 1 and the adventure of link dont look ANYTHING like hyrule in
ALTTP, and they have a much larger coast line, in
LoZ 1 the entire eastern and part of the western half makes it seem a lot like an island (or peninsula judging by the fact it continues to the west and south farther, and that link is from catalia or whatever its called.)
Im not exactly sure which i think is most likely yet though, probably will need to see another game.
Although i do know for sure
LoZ 1 has to be 2nd to last since its says it is the end of the story when you beat the game, and that
OoT has to be first.
