Prologue

Everyone knows that when the Avatar dies, Raava's spirit merges with another human to continue the Avatar Cycle. This has been true, up until now.
After a long period of time, Vaatu has finally become stronger and has fully broken free from the Tree of Time where he has been trapped with the help of a certain Water Tribe chief. Vaatu realized it would really be difficult to defeat Raava because of her connection with humans. Even though he currently has the advantage to defeat the spirit of light, he knows his victory would never last, because the Avatar, alongside with Raava, would always have a way to bring him down.
Instead of trying to get rid of Raava forever, Vaatu decided to use the darkness inside of her so he, himself, can merge with the next Avatar. And now that his powers have been magnified, he could easily lock up Raava and be in control of the next chosen one. It does not matter that Raava will still be a part of the next Avatar, as long as he is the one "guiding" the master of all elements.

Darkness consumes the south pole as the freezing climate keeps everyone from leaving their homes. This is the harshest snowstorm the Water Tribe people have ever experienced, so no one dared to go out and face the dangers that could possibly happen. Meanwhile, a man fully covered in a white and blue winter cloak with its hood up, is sneaking his way behind an igloo, four other people following suit.

"Tonraq, dear, will you please shut the window again. It keeps on opening by itself. Once the weather has calmed down, we should really get that fixed," said Senna, as she puts the last spice her five-flavored soup needed. She smiles as she thinks of her daughter who would be absolutely delighted in eating her favorite Southern Water Tribe dish.
The head of the family stands up from his seat and gives his wife a kiss on the cheek before closing the window. He catches a glimpse of a moving figure outside, but shook it off- thinking his mind is just playing tricks on him. Who would go out in a weather like this anyway? Suddenly, a rumbling noise could be heard and the ground starts to shake. Before he can do anything, there is suddenly a huge hole on their wall and a woman with water tentacle arms steps in.

"Who are you? What are you doing in our home?" Tonraq asks as a bald man with a scar on his face, a tall woman with third eye, and a man with long black hair comes in. The tribesman makes eye contact with his wife and then quickly averts his eyes to the door that leads to his two-year-old daughter's room.
Senna immediately understands what her husband is trying to tell her, so she made a move towards her daughter's room, but was stop when someone used water bending to freeze her lower body in place.

"Hmm, since you're both going to die anyway, we'll give you the honor of knowing who we are," the man with a long hair grinned as he scanned the place. "My name is Ghazan, this lovely lady over here is Ming Hua," he pointed to the water bending intruder, "this intimidating woman is P'li and her macho partner, Zaheer."

Tonraq's eyes widen at the last name. "Red Lotus! Aren't you supposed to be locked up?" He asked the only non-bender in the group. He positioned himself into his fighting stance because he knows this group only meant trouble.

Ming Hua chuckled. "Don't bother trying to make him speak up. He won't talk to you, unless he deems you worthy enough." The tribesman thought they weren't paying attention, so he used this opportunity to gather up large amounts of ice to throw towards the group. Only the tentacle-armed woman got hit, which infuriated the Red Lotus Earth bender, her mate.

Even with all the snow, Ghazan didn't have trouble making the spot where Senna is frozen in place into lava. "NO!" Tonraq explained as he watches his wife get engulfed in a pool of fire.

"I love you and our daughter! S-Save Ko-" were Senna's last words as her body is completely lost under the lava.

The enraged alpha froze the earth bender by water bending the snow around the place and using it to trap Ghazan in a ball of ice. He also did this to the non-bender, Zaheer, who managed to land a kick on him before engulfing him with ice. Which leaves the woman with braided hair and third eye.

Unexpectedly, fire shoots out of her forehead and hits Tonraq's torso, but he quickly put the fire out using his water bending. The impact of the attack made him feel weak. He tried to bend, but he does not have enough power anymore.
A shard of ice appears out of nowhere and stays still in front of him. Tonraq looks at his side and sees the Red Lotus water bender still passed out. A quiet laughter catches his attention. "Brother, wh-" the ice shard pierces through his heart before he can finish his sentence.

"Mom? Dad?" the groggy voice of a little girl was heard from behind a door. The door is trying to be opened, but a huge lump of snow was preventing it.

Ming Hua has finally recovered from being attacked and used her remaining energy to free her boyfriend and Zaheer from the ice trap. Ghazan used his lava bending to dispose Tonraq's corpse. "MOM? DAD? LET ME OUT?" the little girl shouted frantically.

Irritated, Zaheer stood up and glared at the body who is slowly sinking in a pool of fire. "We should all leave now." The three Red Lotus members nodded their agreements and took off with their leader, leaving the water bender, who has ended Tonraq's life, behind. The non-bending leader made eye contact with him. "Until next time."

Said water bender covered all traces of lava with snow before lifting the lump which was blocking the door of the little girl.

"U-Uncle Unalaq?"
