Le laboratoire de Kaer Morhen 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 Épreuve des herbes, which only a few survived. It is this laboratory which is pillaged by la Salamandre organization, apparentlty led by a mysterious mage in the Prologue of the game. Léo meets his end at the hands of the Le Professeur there and Triss Merigold is nearly killed defending it. Vesemir can be found here at times.
