Put Sera in your party and do the quest to find the Red Jenny caches. She will gain approval for each one you find. If that doesn't do it, then following Hawk's questline you should: Recruit the wardens, execute Erimond, and sentence Ser Ruth to the deep roads.
All together that should be enough to trigger her quest.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
