Hello BlackDemon1996,
I've included a diagram that represents my understanding of how the Lucasfilm Story Group categorizes Canon and Legends. According to the Story Group's statements, the six films created by George Lucas and Dave Filoni's animated series, The Clone Wars, are considered the core, unchangeable elements of the Star Wars narrative. Essentially, everything else is constructed in relation to these works. Certain aspects, such as the LEGO Star Wars content, may be ambiguous. Nevertheless, I trust this visual aid will clarify why the six movies and The Clone Wars are featured in both the Canon and Legends timelines. Consequently, Wookieepedia maintains distinct Canon and Legends articles, such as the one for Pong Krell. It's important to remember that this is merely my personal interpretation and not an official declaration. I hope this clarifies things. Andykatib 02:21, October 12, 2016 (UTC)
