Entertainment Weekly reports that the story line for the comics will pick up where the show left off. Michael Dante DiMartino, one of the co-creators of the TV series, has come on board as the main writer.
Brian Konietzko, who is also a co-creator, has been working on the writing with DiMartino and will serve as a consultant on the artwork. According to his Tumblr post, no artists have been hired as of yet.
In addition to this project, Konietzko has also been preoccupied with a science fiction graphic novel entitled Threadworlds. First Second Books has set the publication date for 2017.
