do you mean the mansion near kvatch that was released last year for a limited time?
What I'd like is a massive Colovian Estates zone (chapter 3, perhaps?) that connects the Gold Coast, Reaper's March (fix the bridge at Arenthia!), and Craglorn.
Then all we'd need is a Falkreath zone to connect Craglorn to the Rift, and my dream of a horseback world tour can come true. Yes, yes, I know, Falkreath Hold is a dungeon now... but we could still get the zone with Helgen, Oakwood (town that appears in TES I: Arena), and maybe Riverwood as cities... maybe?
Like the giant nerd I happen to be, I was going to point out that Riverwood is actually in Whiterun Hold. But then I thought, yeah in the fourth era. As far as I know, it could have been in Falkreath Hold in the second era. Also, since it sits on the border of the two, it could easily be included on a Falkreath Hold DLC or chapter.
Too much time on my hands on Mondays.
What is a Calantius? I thought he was a vampire. He was when I played Oblivion.
