Escape Game: Rescue Lucien the physicist

Lucien, the physicist, has disappeared! The last time he was seen, he was working on his time machine... There's every reason to believe that, following a programming error during his tests, he was projected back to the 13th century, to Hyères, at the time of the knights! To bring him back to 2023, you'll have to travel back in time and solve the riddles to find the code to reboot his machine. You have one hour and thirty minutes to bring Lucien back to the 21st century, or he'll be stuck in time forever!

Before you set off, don't forget to bring your city discovery map and a pen.
