A lot has been said about Alduin, his relationship to his Cyrodiilic counterpart Akatosh or Aldmer counterpart Auri-El. He has a hunger to swallow the world, but fortunately Dovahkiin is around to put him and his dragons/Jills back in their place. But how exactly? Dragons can be brought down in conventional combat, but Alduin is a god, and likely the end boss of the Main Quest. In Morrowind, we had to gather three MacGuffins - Wraithguard, Sunder and Keening - and face down Dagoth Ur both in single combat then destroy the Heart to end Second Numidium.
