You are now in Sovngarde (Asgard), the land of valiant dead. Your goal is to make it across this foggy valley to the Hall on the far side. Along the way, you may bump into a few old friends who have died depending on any of the other quests you may have accomplished. About half way across the valley, you will come to a rather large hill that you can use to get yourself situated. Keep moving and when you get close, you will meet Tsun. You must defeat him to get to the Hall. He will use two-handed combat and can hit pretty hard but otherwise, he is fairly simple. Take him down, cross the bridge and enter the Hall. Here, you will meet up with the three heroes from your visit to the past and you will all set out to slay Alduin.
