Back to Act III – Wild Hunt
After discovering that Skjall is dead Ciri decides she must visit his grave and pay her respects. You can automatically travel with Ciri to Hindarsfjall after the Child of the Elder Blood quest or meet her there.
The quest consists mostly of dialogue options. You’ll search for the grave but won’t be able to find it. Apparently his body was thrown into a pit with the animals. Ciri will pull out the body and prepare a proper burial.
The locals won’t be happy but there’s nothing they can do about it. Once Ciri has finished paying her respects you can go back with her automatically or stay in Hindarsfjall and make your own way back.
