Although "The Legend of Korra" is over, Nickelodeon still has more answers to the many family trees in the series.

Recently, Nick.com unveiled a family tree feature on their website, revealing the name of several previously unnamed characters, while leaving some questions behind.

Here is a list of the new character that we now know from "The Legend of Korra" and "Avatar: The Last Airbender" universe.

Unalaq's wife - Malina
Granma Yin's husband - Bohai
Mako and Bolin's mother - Naoki
Chow's (Mako and Bolin's uncle) wife - LiLing
Chow's other kids - Chow Jr. and Meng-Meng
Asami's mother - Yasuko

Although a great number of characters are now revealed, there are still question marks on the family tree, including...

Su's father-unknown
Iroh's wife-unknown
Zuko's wife-unknown

There are also questions as to whether Azula and Sokka had kids or got married after "Avatar: The Last Airbender."

According to ComicBookResources, the next "Avatar: The Last Airbender" graphic novel series is called "Smoke and Shadow," and will be a three-part series like the previous graphic novel arcs. Reportedly, this "Legend of Korra" prequel series will arrive with part one in Sept. 23, 2015. Part two will arrive Dec. 16, 2015.

Reportedly, "'Smoke and Shadow' will focus on how Zuko deals with The New Ozai Society which is set on getting him off the throne, while Mai leads a rebellion against The New Ozai Society."

With this new comic series, perhaps the questions regarding Sokka will be revealed.
