Nigel Stevenson (a young guy in modern times who manages to travel to a fantasy world) is the protagonist of four Italian textual adventures.
In the first, he rescues the two items needed to face an evil wizard who kidnapped the princess of the local realm.
In the second, he travels to the dwelling of the evil wizard and defeats him (freeing and marrying the princess).
In the third, he helps the king of a neighbouring kingdom where a prized amulet has been stolen.
In the fourth, his own realm is affected by several calamities and so he goes to seek the help of the wisest druid, who lives in a remote and wild area.
