Description (IGDB)

The protagonist, Piquet and his friends, get lost in an ancient magical kingdom. Their modern devices are mistaken for unknown magic, and they are mistaken as holy wizards that must save the world, even though they cannot use magic. Can Piquet and his friends, who have become heroes by chance, prevent the mysterious sleeping sickness that is putting the kingdom in danger and prevent the resurrection of the evil wizard?
