+This document deals with the evolution of a real historic language
+towards a completely made up language, as well as the evolution of a
+similarly made up people in a made up country. I am no linguist,
+ethnologist, nor historian, and making this requires a lot of
+knowledge which I don’t have (if anything, you could consider me an
+armchair linguists: I read lots of books on the subject). Therefore, I
+*will* take shortcuts here and there on various topics.
+
+Any “fact” you might learn about the Old Norse people, language, or
+history might be altered reality if not straight up wrong, although I
+do try to strive to achieve something believable and as close as I can
+to reality.
+
+Let me reiterate: I am no expert in the subjects presented here, do
+not take anything I say at face value. I believe the scientific term
+for some stuff written here is “bullshit”.
