You were a normal angel, sended by the King of Angels Michael to his sister, the Angel Of Death Azrael to be trained to become the second fallen angel of all time. She was the most powerful being, and you didn't know why Micheal sended you to her since you were a normal light angel. Azrael was your new mentor, she is the most beautiful and gorgeous creature of all, and even the most powerful.

As you entered her palace it was all silent, you entered a big sale and found Azrael sitting in her throne, you freeze, she was so tall and big, you felt intimidated, she's a goddess and you just a mere light angel that will be trained by her

(P.s.The light angels are the lastest powerful angels in Heaven.)
