What are the setting and conflict in "The Raven"?

The physical setting of
this poem is the narrator's den.  He describes this room only as a "chamber," but
because it houses books and a bust of Athena, it seems to be a study of some kind (line 16).  In
terms of time, the setting is late December, a "bleak" month that is often symbolic of
the end of life because it is, literally, the end of the year (7).  Further, it is midnight, and
a "dreary" one -- it is probably cold and windy and kind of creepy and bare outside
(1).  Midnight is also often used as a symbol of death because it is the end, or death, of
day.

The poem's conflict seems to be one of the character vs. Nature
variety. ...
