Yeah i too have been wondering just who the hell you were before you went to Valheim. After a while, the stuff you remember being able to do becomes eyebrow-raising to say the least.
I mean, not even Odin's ravens know what the eitr refinery is ("warrior, what is that contraption? It looks dangerous!").

That, coupled with Valheim being essentially a purgatory, paints the possibility of a genius supervillain.

Or perhaps, a fallen God...
