I recommend to play the Bull Ending; - Kill Nauxus, Bull Tribe wins, have S** with Axel, reload and pick the Sword Axe. Then play on a much as you like.
The special Scenes* with Nauxus can also be obtained by archiving Peace!! Just follow my posted guide and your Eyvind can enjoy S** with Nauxus AND Thane!
Don't be afraid of restarting the game. I played the public avaible content of the game 4 times already with diffrent outcomes and diffrent Stats Points for my Eyvind, just to see the difffrence between high INT/CHA Builds vs Low INT/CHA Builds.
