Answer:
There may be a moral in Nevermore, but it is not immediately apparent. The poem is about a raven that enters a man's home and perches on a bust of Pallas Athena. The man tries to get the raven to leave, but it will not budge. The man then asks the raven its name, and the raven replies "Nevermore." The man then realizes that the raven is a symbol of his own mortality, and he is saddened by this.
