I love the whole skyrim story about alduin being sent from past to the future accidentally and im in charge for killing him, so i recorded the first fight with him to anyone who wishes to see it:

Also i ask that why didnt i get to use the elder scroll to banish him from the world, instead i got to fight him. Will i be able to do it later?
