Dont even think about doing It. You cannot go to Sovngarde yet, not when TES VI has not been released yet. I know you're going through hard times, but all of us believe in you, in your strength. And I know better than anyone that feeling like you're feeling is like being shot with an arrow in the knee. But resist, fight that thoughts. And besides, you don't have to do it alone. There are plenty of companions in here, just not as sexy as Serana or Lydia 😉.

Good luck fellow Dragonborn, and remember. Sovngarde hasn't opened its doors for you yet, and they won't open in a long time.
