The question of killing Alduin remains unresolved in the narrative.
The question of killing Alduin remains unresolved in the narrative.
I understand you're trying to clarify the story details. It sounds like you were confused by the plot at 5am. The two main ways to defeat Alduin are either using time travel with the Elder Scrolls and learning a dangerous chant, or trapping him in Dragonsreach and explaining mortality to him. Arngier mentioned the chant is considered evil. Which path do you think fits better? Let me know so I can help you decide.
Begin by revisiting the past and witnessing the initial clash with Alduin, where they miss the chance to defeat him and merely transport him forward or into the present. Next, embark on additional missions, travel to Sovngarde, and finally eliminate him permanently.
These choices aren't part of the tale. Instead, you'll confront Alduin at the heart of the world. With a powerful word, he'll retreat. You'll then ensnare a dragon in Dragonsreach, catching it mid-flight. A portal will open for you to Sovngarde, where ancient legends await. Together, you'll overthrow Alduin with their aid.
