The Toussaint Prison Experiment

Wandering about the slopes of Mount Gorgon, Geralt came upon some grim, foreboding ruins. He set about exploring them and nearly tripped over a corpse. As always, he searched the body for a journal or letter that could shed some light on the circumstances of the individual's death. This time, too, this routine paid off. He found a journal and a key…

The journal detailed an unsuccessful experiment that had resulted in Bastoy Prison being destroyed. The witcher also learned of a chest full of gold that remained hidden within the ruins.

Geralt located the chest. The key he had found with the journal worked like a charm. So the witcher scooped up the gold and ran off to spend it!
