Set in 1767, the story takes place during an exclusive and fictional masquerade hold at the Bargellinis’ mansion, the private residence of a Bolognese senatorial family. The player can customize their own avatar during the interactive experience (by choosing every feature of their persona such as preferred pronouns, looks, accessories, profession and name) and can then interact with the unique scenarios offered by The Invitation. The story can be explored trough 6 different routes, one for each NPC (non-player character) developed for the application: the cast is made up by fictional characters inspired by figures of the time (such as, for example, Lazzaro Spallanzani) and it can be described as diverse, historically accurate and, obviously, irresistible. The game is intertwined with the non-virtual activity accessible at the free visit at Palazzo Davia Bargellini, the story’s setting and the  inspiration behind the application itself: these experiences are inherently connected and can influence one another from a cultural and emotional point of view, therefore it is advised and encouraged to visit the museum before starting a route.
