You've been transported to Europe, ca 1000 AD. Can you survive, or better yet, thrive?
SeverinR is Severin Rheinfelser, circa1310
I would stay in the Rhein river area, Specifically in area that will be the sight of the Rheinfels castle near St Goar. Which would not be built until 1245.(long after I have gone)
I would learn to hunt, fish and work with a sword. Maybe work on the river and try to avoid the fights in that time.
