Is one of the oldest and surest ways of telling a story. The form of a quest narrative is simple:
Basically, the author describes his or her desire to do something, see something, experience something, discover something.
In describing the object of the quest, whether a grail, or castle or insight or pot of gold, it's helpful to "sell" the quest, emphasizing why it's important either to the writer or the reader.
Since the writer is the reader's surrogate, describing why you want to go to Rome is often enough, especially if you can make it seem an especially appealing destination.
