WotC D&D website is crap nowadays, I can never find anything. Between that, D&D Beyond, Facebook, Twitter, Twitch, etc I miss alot of news/discussions because Im not on any. I wish they just pick one place to give their announcements, but I get it times have changed and Im a little behind. I think one thing that gave me the impression that FR was default is the factions in the DMG are all from the Realms doing a quick perusing just now. I know they're examples, but I think people have have a tendency to disregard or recognize this.
