And it is obvious that the lore in ESO had to be bent quite a bit because of the fact that it is an MMORPG. The inconsistencies were to be expected.

The only possible way for these inconsistencies to fit in with Bethesda's lore would be for there to have been a Dragon Break prior to the events of ESO, but so far that has not been clearly alluded to in-game.
