Since I haven't read the 'So Speaks the Heart Novel', I can only guess. There could be a strong - willed female lead who is trying to find her voice and express what her heart truly desires. There might also be a male character who either helps or hinders her in this journey of self - discovery. Another possibility is an older, wiser character who acts as a mentor and guides the main character to understand the messages from their heart.
I'm not sure as I haven't read it specifically, but it could be about love, self - discovery or human relationships.
Natsu would surely be one of the main characters since it's about him speaking dragon. There might also be some dragons as main characters, like Igneel if he's still alive in the fanfiction's storyline.
It's possible that in addition to the well - known Twilight characters, there could be new characters introduced that are related to the concept of the soul speaking. Maybe there's a mysterious character who has the ability to communicate with souls and they interact with Bella, Edward, or Jacob, changing the dynamics of the story.

Obviously, Harry Potter is one of the main characters since it's in the title. There might also be Hermione and Ron as they are always by Harry's side in most fanfictions. Ghosts like Nearly Headless Nick could also be important as they are the ones Harry can potentially speak to.
It's also possible that the main characters are part of a group or community. They all might be facing some sort of crisis that requires them to tap into their inner phoenix - like qualities. Maybe there's a young character who is the key to the group's survival or revival, much like how a phoenix can bring new life or hope to a desolate situation.
