Self Promotion Time: Just a reminder, Gray Whirlpool (my Fates plot parody) is up and has reached its second chapter.

Brother and Sister
Cast: (Lilith, M!Corrin x Azura)
Prompt: Lilith tells Corrin (and wife Azura) about who she really is

Peace had been restored to Valla. Or rather, the idea of Valla. Much of the land and people were lost, but many had been able to find refuge in the new Valla, under King Corrin's rule. It seemed that finally, the Vallites could know happiness. All except for one.

Lilith had long ago been created by Anankos, as a personification of his madness. She tried to serve him, before eventually setting out to meet his other spawn- his son. Lilith vowed not to reveal any truths of her connection with Anankos and Corrin, out of remaining loyalty to her 'father'.

But everything changed. Anankos was laid to rest. It pained Lilith, yet she still found herself overjoyed when Corrin, the kind little boy she had met trapped in the Northern Fortress, the young man she had taken to the Astral Plane, her only family left, became the new king of Valla. Once things had settled, she had decided that it was time Corrin knew the truth.

Laslow and his friends- or rather, Inigo and his friends- had already divulged some truths to Corrin, namely their own past and meeting Anankos. He took it fairly well, and while this alleviated some of Lilith's concerns, revealing deep secrets was never easy. But Lilith was ready.

Lilith had stayed in the Astral Realm, but liked to visit Corrin in his new castle (an old, repurposed fortress near the Bottomless Canyon). Corrin looked forward to these visits, and always greeted her with that smile she had loved so much. The dragon found Corrin talking to his wife on a balcony. It would be easier if it were just Lilith and Corrin, but she imagined Corrin's wife, another Vallite, should know too.

"Oh, Lilith! It's good to see you again," Corrin greeted, turning away from Azura. They both smiled. "What brings you here?"

"Oh. Well…" The little dragon hovered closer to the ground. "Do you remember when Laslow, Odin, and Selena told you about how they first came to Nohr? About… your father?" Stupid question, but she needed to start somewhere.

Corrin nodded. "Of course. What about it?"

Lilith noted his patience, as if she were about to tell him a neat factoid instead of perspective-changing information. That patience encouraged her. "They did not know this at the time, but I had met them before, back in…" It took a moment to realize she could discuss Valla, without Anankos to sustain the curse. "I had met them long ago, in the old Valla… as an enemy."

Corrin gasped, as did Azura. She was the first one to speak again. "Does that mean that you served Anankos, back then?"

The dragon sadly nodded. "Yes…"

King Corrin smiled warmly. "That's okay, Lilith. The important thing is that we're friends now."

"There's more," Lilith warned. "Corrin, Azura... Anankos was my father. He created me from his madness, and used me as a tool." The memories began to hurt, her eyes were watering. "He never loved me… But then his soul came back to Valla with those three heroes. He ordered them to leave… and then took an attack meant for me, even though I was sent to kill him!"

"Oh, Lilith…" Corrin's heart sank at the sight of his friend so distraught. "I hate to see you like this. I wish I could've been there to help…"

Lilith started to feel better, chuckling a bit. "Hm…! You were a small child at the time, Corrin… You wouldn't do much. Haha!"

"Hey, I seem to recall nursing a baby 'bird' when I was still a child, haha! Surely I wasn't that useless!"

"Hahaha!"

Azura smiled, letting Corrin and Lilith share their moment. But then a realization dawned on her, and she felt compelled to interrupt. "Wait. Lilith, if Anankos created you and you called him 'Father', wouldn't that make you-"

"That is correct, Azura…" Lilith turned to Corrin. "Corrin, in a manner of speaking… we are family."

Corrin's eyes widened. Even Azura seemed stunned, having her suspicion confirmed so quickly. But Corrin was able to recover from the surprise quicker. "Well, what do you know, Azura? I have another sister!"

"It appears you do," the singer said with a small smirk.

"I would have originally never told you," began Corrin's sister, "but… I never thought you would go on to defeat my- our father, let alone become the new king of Valla. Thus I felt that you had the right to know."

The king nodded in acknowledgement. "Well thank you for being honest."

"Yes, thank you," Azura added. "I know we haven't spoken much, but it's nice to get to know you a little better."

Words would fail to describe the elation Lilith felt. She had bared her soul to Corrin, the human brother she had sworn to protect, and he received her. Of course he would, Lilith remembered, he even trusted Gunter after the man had explicitly betrayed everyone. Nevertheless, Lilith was glad to know she held a place in Corrin's heart.

Corrin then had a thoughtful look. Lilith and Azura seemed a little confused. The former spoke. "Corrin, what's the matter?"

"I want to try something. Could you hold still, please?"

"Oh… Okay?"

Corrin slowly reached out for Lilith and then held her in his hands. Just as slowly, he placed her against his chest. "… Hmm."

"Corrin, what are you doing?" asked Azura.

"I wanted to give my new sister a hug." Corrin's eyes turned down to the dragon he was holding. He began to speak to her instead. "You've been through a lot and have done so much for me, and sometimes I feel like I never truly repaid you."

FLASH

"Aaah!" Corrin and Azura both screamed, caught off-guard.

When they regained their vision, they were shocked. Lilith was her old self again. She seemed to be surprised as well, examining her hands. "I'm… I'm like this again?"

"I thought you said you couldn't do that again," Corrin stated.

The transformed woman was still looking at her hands. "I thought so too… The Astral Dragon Moro must have granted me this favor."

Corrin smiled. "It might have been because you were a good sister."

Lilith's eyes began to water again. She immediately reached for her brother and wrapped her arms around him. Corrin closed his eyes and returned the gesture. Azura watched the two of them. She felt happy for her husband and his new sister, though wondered if she should have been there for this. As if to answer her question, Corrin and Lilith's smiles grew, as they wordlessly grabbed Azura and included her.

At that point, Lilith had a gut feeling. Somewhere, the kind soul of their father was at peace. Proud of his two children.

A/N:

I'd sort of wanted to write for Lilith, and then someone makes a request about her just in time. So I volunteered.

I was a little unsure of turning her back to human at the end, but I felt that if the Astral Dragons could transform her just so she could die as a human, they could probably do this for her here.
