A lot of random events that have potential to tie together. Alduin was Aedra-spawn, but he kind of went mad. And all the Deadra don't inheiently claim the heroes as their champion (that's something you do as a choice, it's not part of the main quest). Traditionally, based on the conversations you have with NPCs and the way the books read in-game, only events that happen as part of the main quest and the DLC main quests become hard cannon. Everything else is left open.
