Queen of New Orleans

What if someone was more powerful than the Mikaelsons? She was born in March 1900 to one of the most powerful witches around, Isabelle Anderson, and the angel of death, Azriel Cambrian. She was a hybrid both angel and witch something that the supernatural world had never seen before and she tried her best to keep that a secret but she let her guard down with the Mikaelson family after one of them saved her life. She became a part of the family however, she made a trade for her immortality after saving Marcel from a fire in 1919.
