I heard theyre making a new series, it will be about Zuko trying to find his Mother, or something like that. Is this truth of what I speak, or are they just tales told by one who fibs?

I am not 100% sure that there are going to be any new series based off of Avatar: The Last Airbender. A series based off of Zuko? Well it could be possible, but I'd say this show is done and no series are yet to come, there's a lot of different information on the internet but is any of it true? That's something I'd like to find out. However, I do know that three live-action movies based on the show: Avatar: The Last Airbender are coming soon.
