The Alchemist

Explore the city and its medieval past to unravel the truth about witchcraft 🧙🏻


Alexia Peren
Storyline by Alexia Peren

We are in the year of grace 1555 and strange phenomena are taking place in the city. Josyne, a villager accused of witchcraft, is arrested before your eyes by the city guards. In order to distinguish between true and false and to identify the reasons for this accusation, go and meet various witnesses and examine the clues discovered in the various places you visit along the way. Organise her trial to find out the truth: will you choose to defend Josyne, or will you choose to support the accusation of witchcraft? As an alchemist, will you be able to use your skills in this investigation, based on real facts, in time?

Super expérience dans Lausanne et beaucoup de fun avec ma meilleure amie. Nous avons tout de même eu un petit problème à la fin, un des lieux était fermé temporairement mais la prochaine énigme (trouver quelque chose sur le bâtiment) nous a tout de même été posée. Mais globalement c'était génial! Merci pour votre travail!
