Forgotten Gods or original content?

So I have the definitive edition and am about level 22. I saw the emissary and I have a choice to play FG or continue the original campaign. If i choose FG will i skip a bunch of content? Thanks in advance!

You won’t skip it because you can always come back to the other content at any time. However, the smoothest progression is to do base game, Ashes and then Forgotten Gods.

Thank you that’s what I kind of figured.
