* What story or movie are you referring to? A raven named "Edgar" might be a pet in one story, but a raven named "Shadow" in another.
* Who is the owner of the raven? Knowing who owns the raven can help me narrow down the possibilities.
* What is the raven's personality like? This could give me clues about its possible name.
Once you provide me with more details, I'll be able to answer your question!
