Developing a personal canon isn’t really compatible with how I like to enjoy this sort of fiction with big, sprawling universes. A big part of the appeal of Star Wars, and LOTR, and A Song of Ice ad Fire, etc. is the fact that I’m given access to this world I had nothing to do with creating in which I can poke around and look under rocks, so to speak. I find that picking and choosing what I want to “count” for myself makes me too much of a participant to be able to immerse myself as an observer the way I like to do. So, I guess I just accept the official canon (with Legends as an alternate timeline), and I focus on the stuff I like, and I don’t dwell on the stuff I don’t.
