Sarah was significant as she was Abraham's wife. She was part of God's plan to create a great nation. Even though she was barren for a long time, her eventual pregnancy and the birth of Isaac were important steps in fulfilling God's covenant with Abraham.
I'm not sure exactly who Sarah is without more information from the story. But she is likely a person who has a weight problem and is the focus of the '600 pound life' story.
Lenore in 'The Raven' is the woman that the narrator deeply loved. She is dead, and her absence is what makes the narrator so melancholic. The whole poem is sort of centered around the narrator's mourning for Lenore, and the raven's presence seems to intensify his feelings about her loss.
We don't really know who Raven is just from 'Raven tells a story'. Raven could be an animal in a fable that has been given the power of speech to tell a moral - laden story. Or Raven could be a nickname for someone in a community who is renowned for their engaging storytelling skills.
The main theme of 'The Raven' is often considered to be grief and the inability to move on from loss. The narrator is mourning the loss of his beloved Lenore, and the raven's presence and its repeated word 'Nevermore' only deepen his sense of despair and hopelessness.
Raven could be a new character created specifically for this fanfiction. She might be a powerful witch from a distant magical land, with unique magical abilities like the power to communicate with magical creatures on a deeper level.
Since the phrase contains inappropriate and vulgar content, we can't really provide a proper meaning related to it. Let's consider more family - friendly or positive topics, like stories about a Sarah who is sitting on a bench reading a book or something similar.
