Oath of Lies

Y/N is killed by an angel. Unbeknownst to Y/N, this angel kills her for the Myth Malumn, who he wants back in power. Her soul is sent to the Indefinitum. Through a ceremonial test, she gains her wings and is sent to the Academy, where she'll choose her path of Angel or Demon. She quickly grows close to Maze, Raum, and Adriel. She is plagued with finding who killed her in her past life. Yael and Lucifer seem to turn up when she needs help discovering how she was murdered. While in the Indefinitum, she goes to classes at the Academy to learn how to adapt to her new afterlife. Soon, she finds Bonum, locked away at the edge of the Academy. She realises that he's one of the answers to figuring out her murder, and slowly becomes obsessed with saving him. Soon, an angel and demon are killed, and her connection to the myth Malumn Bonum grows, and she becomes plagued with dreams/visions of a burning tree. It doesn't take long before she figures out that Lucifer is also plagued with these same dreams/visions. She ends up growing very close with Maze and Lucifer. Soon, she saves Bonum, and is forced to decide if her after life is worth giving up to save him and solve her murder.
