Don't underestimate how much you have left - the area you've just got to is pretty expansive.
In other news, I just finished the main story of Witcher 3
- the following endings occurred:
Ciri survived after I assume ending the White Frost, although that's kind of ambiguous
Radovid was assassinated and Nilfgaard conquered the North, but freed Temeria anyway.
Cerys ruled Skellige.
Ciri left Geralt to become Empress.
Geralt retired with Yennefer.
All in all, I feel like it's a positive ending although I'm not entirely sure how some bits came to pass.
There were a few other bits that they worked in - like
Keira and Lambert falling in love and The Baron taking his wife to the Blue Mountains and Dudu taking over for Whoreson Jr .
I've still got a couple of unanswered questions though, which I assume will remain so because the DLC doesn't look to tackle them, namely:
What happened with the other Crone that escaped?
What happened with Novigrad? I assume Nilfgaard takes it over and gets rid of the witch-hunters?
What happens with the Aen Elle and Avallac'h?
Triss? No ending for her?
Phillipa and the Lodge? I assume they take over as advisers for the Emperor/Ciri.
Anyway - they're very minor things - and some of those points were probably dealt with in the other endings that occur if you make different choices, but it was still a bit niggly.
