I recently finished my first playthrough of the Witcher 3 and in the epilogue I got it was mentioned that
mad King Radovid has conquered all of the North including Novigrad and due to his hatred of all magic is persecuting and killing anyone related to it, including Herablists and Sorceresses.
All in all rather bleak. This really messed with the rest of my happy ending.
I can't remember having a quest related to it. I suppose it has to do with the Vernon and Ves' quest line.
Can I, and if so how, how can I avoid the rather bleak outcome?
I highly appreciate for the answer to be as spoiler-free as possible.
