I wouldn't be surprised if we end up as semi-permanent residents at one of the two taverns mentioned, the Elfsong and...the other one, especially considering they're mentioned a few times by people expecting to meet us again.
By saying we'd get background specific quests I didn't necessarily mean quests dealing with our history, but more like when Geralt was given the run around in Novigrad to get a blacksmith to work on a sword...something that gets us moving around and meeting people through the lens of our background.
But we should have some history in BG, considering coming from there is the default for every character, even Outlanders.
