Zdrada
From Witcher Wiki
"Zdrada" (The Betrayal) is the 6th published The Witcher graphic novel (after "Granica możliwości") and the 2nd one in the order of internal chronology (after "Droga bez powrotu" and before "Geralt"), written by Maciej Parowski and illustrated by Bogusław Polch.
It is the only one of the Witcher comics not based on a short story by Andrzej Sapkowski, being based instead on a basic idea by Sapkowski, expanded by Parowski and Polch. It is set during Geralt's youth and his witcher training, and tells of the betrayal of the Cat School of witchers that led to the massacre of Kaer Morhen.
