Haunted Florence: Step Into Dante's Inferno

You are Dante Alighieri, the greatest poet Italy ever had, the author of the world-renowned Divine Comedy, with its three parts: Hell, Purgatory and Paradise. In these works, you claimed to have visited all of these 3 places within a week, in a divine journey, before returning to Earth with the mission to write down your experience for others.  

The years have passed and you have too, the world never knowing if what you said was ever true. Now, seven centuries later, on the night of 27 October, you came back to Earth as a spirit, after undoubtedly seeing the other side. Find a way to let the people know you were right.
