The quote presents a haunting image of darkness and death, where all lights are extinguished, symbolizing an end to life. The metaphor of a curtain descending like a funeral pall suggests a finality and sorrow, akin to a storm's overwhelming force. It conveys a sense of despair as life comes to a conclusion, leaving only shadows behind.

The mention of angels who are "pallid and wan" adds to the somber atmosphere, indicating that even the celestial beings are affected by this darkness. They rise and unveil themselves, perhaps signifying a revelation or acceptance of mortality. Overall, the quote evokes feelings of loss and the inevitability of death, characteristic of Poe's thematic focus on the macabre.
