Overview
''Unalaq has finally merged with Vaatu and is terrorizing Republic City in the form of a giant spiritual monster. Without Raava or any prior Avatar connections, Korra must meditate and find the cosmic energy of the universe within herself in order to defeat Vaatu.''

Synopsis
Unalaq, now the Dark Avatar, enters the physical world and begins terrorizing Republic City. Though General Iroh leads the United Forces in defending the city, the United Forces are unable to do any damage. The Dark Avatar attacks a nearby airship carrying President Raiko and Lin Beifong, forcing them to bailout.

Meanwhile, Tenzin, Kya and Bumi, find Korra, Mako and Bolin lying unconscious. Kya is able to heal their wounds after immersing the trio is spirit water. After being informed of Jinora's rescue, Korra informs Tenzin of her forced separation from Raava. Korra sadly notes that she no longer has any connection with her past lives, and that the Avatar Cycle has been broken. Korra, believing that Vaatu has won, apologizes to Tenzin for failing.

Tenzin reveals to Korra that there may be another way to defeat Vaatu and Unalaq, by having Korra connect with her inner spirit. He takes her to Vaatu's former prison, called the Tree of Time. Tenzin explains the tree is believed to hold the physical and spiritual worlds together and that the ancients once meditated to connect with the cosmic energy of the universe. Stepping inside, Korra sees memories of her life; Tenzin reminds her that that Wan became great not because he was the Avatar but because of who he truly was. Tenzin instructs Korra to meditate and connect with the cosmic energy of the world. As Korra meditates, she sees Wan speaking with Raava as Raava explains that neither she nor Vaatu can truly destroy the other.

Korra suddenly finds herself in a strange location, on a pathway of light. Seeing a representation of her spirit, she walks into the sphere of light the spirit is holding. Back at the tree, Korra manifests her spirit as a giant blue entity. Korra's spirit then uses the spirit portals to return to Republic City, with the goal of defeating the Dark Avatar.

The Tree of Time shows her many memories. It shows her how Raava told Wan that neither of the two spirits can be destroyed by the other. It also shows of the danger Republic City is in. Korra connects with her cosmic energy.

Her light spirit comes out of her body.

Her spirit comes out of the Tree of Time and exits through the Southern Spirit Portal.

Spirits try to attack Korra's non-cosmic body. Mako, Tenzin, Kya, and Bolin protect her.



She goes to Republic City and fights the Dark Avatar. Jinora comes in spirit form and helps her.She locates Raava's spirit inside Vaatu's body. They then destroy the Dark Avatar and it fades away.

Jinora wakes up and tells Katara, Tonraq, Senna, and Asami that Korra had won. They all rejoice.

She combines with Raava and begins the 2nd Avatar Cycle. She presumably has her connection with her past lives in the 1st Avatar Cycle severed.

Korra makes a speech and frees the Southern Water Tribe from the Northern Water Tribe. She then announces Tonraq as the tribal chief of the Southern Water Tribe.

Bolin tells Eska to move to Republic City with him. She tells him that she must go back home but she will always love him.

Mako and Korra discuss about their earlier break up. They decide that they have different goals in life and that their relationship will not work out. They end their relationship on a happy note.

 * Korra loses her connection to her past lives and thus must restart the Avatar Cycle.
