Hi BlackDemon1996,
I have attached a chart of my understanding of the Lucasfilm Story Group's classification of Canon and Legends. Based on what the Story Group said, they regard the six George Lucas movies and Dave Filoni's The Clone Wars as the "immovable objects" of the Star Wars universe. Basically, everything is built around them. There are some unclear areas like LEGO Star Wars. But I hope this chart explains why the six movies and The Clone Wars appear both the Canon and Legends timelines. This is why we at Wookieepedia have separate Canon and Legends versions for articles like Pong Krell. Please note that this is completely unofficial and is basically just my interpretation of their statement. I hope this helps. Andykatib 02:21, October 12, 2016 (UTC)
