Prologue

The witchers' laboratory holds their most closely guarded secrets: mutagenic plants, hallucinogenic mushrooms, natural stimulants and potion ingredients. It is here that young apprentices, like Leo are subjected to the fabled Trial of the Grasses, which only a few survived.

It is this laboratory which is pillaged by the Salamandra organization, apparently led by a mysterious mage in the Prologue of the game. Leo meets his end at the hands of the Professor there and Triss Merigold is nearly killed defending the lab.

Vesemir can be found here at times.
