Charles Lanzano was a man that posted a notice looking for a witcher to investigate the noises he was hearing from the Temple Cemetery. He had asked the Ducal Guard to investigate, but they claimed they had found nothing. Charles could not bear to keep hearing the noises as they kept him up at night, and thus posted the notice.
In the year 1275, if Geralt chooses to help him he will meet the ghosts of Margot de Corentin and Louis de Corentin. If Geralt solves the problem, Charles is ecstatic, saying he can finally sleep in his own bed.
