3:27 PM in a nearly destroyed Republic City.

You have finally defeated Vaatu but you realized something.

Putting him back in the Tree of Time was only a temporary solution.

He'll eventually break out again in the next 10,000 years and who's to say that the Avatar will not fail? I mean, you had a close call this time.

Knowing this, you decided to take a leap of faith and begin to merge with Vaatu.

"What are you doing, Avatar!?" - Raava said with shock.

"Putting a end to this." You said.

Tapping into your Avatar state, you focused.

For years, It's been about balance: Fire and Ice, Light and Dark, White and Black.

But now was the time for something new. Unity: Steam, Chiaroscuro, Gray.

"I'm not sure this is a good idea." - Raava said.

"Trust me, Raava." - You reassured her.

"Okay, I trust you know what you're doing." - She said.

Putting all your focus into combining two opposing forces, a combination of blue-white and dark-red would cover the area.

Hours later, you would wake up in a huge crater and feel....stronger.

You also felt not one but two spirits were in you: Raava AND Vaatu.

Your connection to the Spirit realm was much stronger now.

"Raava? Are you alright?" - You said.

"Yes, i am." Raava said.

"I must say: Out of all my years, I didn't even think it was possible but you manage to prove me wrong." Vaatu suddenly said with annoyance and surprise.

"It had to be done, you almost destroyed the planet." You said.

"No matter, i will eventually break out of this body and when i do, I will purge this world into darkness." - Vaatu said with dark anger.

"I won't let you!" You yelled.

"Calm down and ignore him, Avatar. You did something that not even Avatar Wan or Aang could do: Bring Me and Vaatu back together." Raava said.

"You are now something bigger, something more than a Avatar."

"You are a Equinox, A being of light and dark." - Raava said.
