>>5884I couldn't find a long-past war that made enough sense or a more recent one with enough connection to dragon times.
I also considered the possibility that the book is more recent than it appears. Maybe Gjalund's scribe had access to ancient tomb inscriptions or something, or someone was sent up to High Hrothgar to ask the Greybeards because Gjalund was a dragon weeb (the old gods in "the old gods and the new" might be dragons if Gjalund was a cultist).
However, the language seems to be archaic, and the discussion of taking part of the Reach from Reachmen is a much better fit for early Nord conquests than the recent Forsworn phenomenon. Also, if Gjalund was that recent, you'd expect people to mention him.
So the book is old and the stead is new. Rorikstead is built where Rorik's Steading was. "Old Rorikstead" specifies the previous town as opposed to the present one. The biggest hole in this is that Rorik never mentions that he was the town's namesake before it was named after him.
Or maybe by returning wounded from a war and buying land he mantled the original Rorik and blah blah blah patterns in history, craft spell, max damage, target self.
Lorefag bonus: my best candidate conflicts for an earlier Rorik were the Three Banners/Alliance War in the Second Era and – brace yourself – the Ayelids declaring imperial independence from Alinor at the start of the First Age. The term "Dominion" wouldn't have been used at the time, but is a reasonable way for a time capsule person to describe it to some rube wandering through Fourth Era Skyrim talking to everyone and picking woodcutters' pockets.
