It would be nice if he was a friend of the goblin in his early years

Please save Minato and Kushina

I'm hoping the is more than three world, just because I think it would be a short story depending on how you write each world or volume.

Probably physical, I don't see him being able to use magic so I figured he could be a heavy hitter/tank. Also does he age or not because I don't see him being in a relationship with an immortal working out if he doesn't have immortality. (That is if your pairing him with Alduin). I also would prefer a harem for this fanfic just because there aren't any good harem fanfics for skyrim of elder scrolls in general and there are some fairly beautiful woman in Skyrim/Elder Scrolls.

Are you going to make him stronger and is this a harem? If so who's in it?

Please save Uso

So far so good

This is good, Keep up the good work. Also question do you have the plot planned out? If not, He could go to Xavier's institute for gifted children for blood donations.
