Perfec' ~ CDPR you've found your new writer.They can become Radovid's adoptive parents, I mean, he is younger than Ciri, perfectly viable. Triss can teach him that not all mages are evil (only like 99% of them) and Geralt can teach him some ways to turn black ones into mince meat.
Redania becomes paradise on earth. It would be beautiful.
That image cannot form in my brain without almost killing me from perfection.
