In the Internet world, eight years seems like an eternity. Even in the normal world, eight years is quite a long time. In the autumn of 2014, Call of the Northland was published, including a website to host errata and updates. After nearly a decade, I've decided to close down that website. As of today, northland-book.net is no more. Of course, it does live on in the Internet Archive.
So, if you happen to find northland-book.net somewhere on the Interwebs, it won't be me. If you wanted those errata and updates, you can find them here.
