One of the main themes could be transformation. The raven's refusal to sing might symbolize a resistance to conform, which is a form of transformation. Another theme could be the relationship between humans and nature, as the raven is a part of nature and its actions or inactions have an impact on the human perception in the story.
The raven, of course, is the most prominent character. It's not like an ordinary raven as it has this special trait of not singing. There could be a storyteller type of character, someone who observes the raven and relays the story to others. This character might be in awe of the raven or frustrated by its lack of singing. There may also be other animals in the background that are affected by the raven's behavior in some way.
I recommend a novel called "The Law of a Woman Who Dresses Quickly to Get a Superior Position" to you. Although it's a sci-fi space-time travel genre, its plot also involves the male protagonist ignoring the female protagonist and even letting other women sing. The female protagonist of this novel was like the female protagonist in "The Woman Who Transcended the Ages", who went from being ordinary to being successful and was no longer ignored. I hope you like this fairy's recommendation. Muah ~😗
The raven could be quite aloof towards other characters, much like Severus. It might only show interest in those who Severus trusts or has a connection with.
Often, there are other animals like the Eagle. The Eagle is usually portrayed as a noble and powerful character, sometimes in contrast to the Raven's more mischievous nature. There are also the Salmon, which are important as they represent a vital food source in the Northwest Indian culture. And the Bear can be another main character, often seen as strong and somewhat of a force to be reckoned with in the stories.
Well, this graphic horror novel likely combines the classic elements of Edgar Allan Poe's 'The Raven' with other tales. The graphic format allows for a more visual and immediate impact of the horror. It might use different art styles to represent different levels of horror, from the subtly creepy to the outright terrifying.
The 'New Teen Titans' run also has great Raven stories. Here, Raven's relationships with her teammates, especially her budding friendship with Beast Boy, are a key part of the narrative. The story delves into her internal battles and how she uses her powers for good, despite the dark forces within her constantly tempting her.
The raven in dark stories often symbolizes death, mystery, and the unknown. It is a creature that brings an air of foreboding. For example, in Edgar Allan Poe's 'The Raven', the raven's repeated 'Nevermore' adds to the sense of despair and the inescapable doom of the narrator.
One origin story of the raven is from Native American folklore. In some tribes, the raven is seen as a creator figure. It is said that the raven brought light to the world by stealing it from the gods. Another origin story could be in Norse mythology where ravens were associated with Odin. They were his messengers and would fly all over the world and bring back information to him.
