Witchers’ Secrets

Witchers’ Secrets is the main quest that runs through the whole of The Witcher, starting in the Prologue. After Salamandra raids Kaer Morhen, steals the witchers’ secrets and kills Leo, Geralt sets out to get the secrets back and make the attackers pay.

The hunt leads from the Outskirts into Vizima, where Geralt hears the name Azar Javed and works with detective Raymond before learning that Azar had been posing as him. Along the way Geralt takes down the Professor and Azar Javed, and the trail ends with Jacques de Aldersberg, Grand Master of the Order of the Flaming Rose, who turns out to be behind Salamandra and holds the stolen secrets.
