Disclaimer: I do not own any of the mentioned characters or other fictional elements used in this story. This fanfic was written for fun.

A/N: It's finally here! The last chapter of this story has been uploaded. (Perhaps I might do some follow ups… but I'm still unsure). Enjoy!

Everyone had gone to their respected rooms to have some sleep… except one. She was glancing towards the sea, hearing the waves crashing against the shore while feeling tiny bits of sand beneath her feet.

"You said you were here to help me, am I right?"

"Yes".

She turned around to greet her visitor. Shinning eyes were gazing at each other.

"Can you do it by answering my questions?"

The female ghost nodded her head while responding. "I will provide you with as much information as I can".

"Back when we first met, you mentioned that there are other beings like us…".

"Yes and no".

The younger woman raised her brows as if being confused. This didn't go unnoticed by the spirit.

"To make it simple, we are at the top of our species' hierarchy".

"You're saying that, due to this condition, it would give us some advantages…".

"Certainly".

"For example?"

"One of those given benefits would be the fact that we are of the most powerful among our kind. Strength, speed, stamina, healing, and many other abilities were bestowed upon you. There are still much more gifts that you will eventually discover".

The deceased woman looked to the stars while continuing with her speech.

"Aside from that, thanks to your blood heritage that you received from your father, you are immune to some of our weaknesses".

"Like what?"

"You have the fortune of being able to walk in daylight without being burned down to ashes. Even I am incapable of doing so".

The younger one looked down at her hands. Ever since the moment she was able to see, she has had the desire of examining every detail of the world. With the eyes that she now possessed, she was even capable of seeing every single blood cell that traveled across her veins. There were many things she yearned to discover with her newborn sight. The mere thought of it being taken away from her again caused some shivers through her spine. Yes, she had lived her life in the darkness, but she was now finally able to escape from it. At least, that's what she thought. Besides, she also loved the warmth of the sunrays kissing her skin.

Now, with a trembling voice, our main protagonist had finally found the courage to ask about the things she desired the most to find out about.

"What's your name?"

"Amelia".

"Are you… are you my… my mother?"

"Yes, my child".

"Did you get rid of me when I was a baby?"

"No! My love for you was so strong that I vowed to myself that I would protect you with my own life. And that's what I did…".

"Does that mean that… you were killed?"

"Yes, and the ones who committed the act abducted you and sent you here so that not even your father could find you".

"Why would they do it?"

"There are many beings that would do anything for power. You have been a witness of it given your current circumstance in this place".

Yes, the royal members of the Fire Nation have proved such hunger that they were able to attempt against the life of one of their own.

She wanted to hug her mother so desperately. But how could she do it if her mother was now a spirit that couldn't be touched? It made her feel impotent. But at that moment, another thought had crossed her mind.

"This means that I must have a family out there".

"Yes, my dear".

"Mom…".

"What is it?"

"I have one more question to ask you".

"Request me anything".

"What is my name?"

"Your name is Helena Corvinus, daughter of Alexander II Corvinus and Amelia Maximus, granddaughter of Alexander Corvinus, the first immortal. You, my child, are a vampire".

A/N: So, the idea of writing this fic has been in my mind for quite a while. A few years ago, I was obsessed with ATLA's world and with Underworld's cinematic Universe. I love how the latter one had managed the vampire's and werewolf's concept. Plus, I was interested in those type of topics back in those days. So, I thought to myself, "why not do a crossover involving these two Universes?" The reason as to why I didn't include this fic in the Underworld category was for the fact of avoiding any spoilers (even if the story might have been predictable). I want to thank you all for letting me share this fanfic with you and for spending some time reading it. I hope to be writing some more fics and uploading them for you. I wish you all a lovely day (or night)!
