The canon page on this wiki definitely needs to be redone. Saying that only the first nine levels are canon kind of ruins the whole point of this wiki. If you truly accepted this canon, you probably wouldn't be editing this wiki to being with.
Also, alot of "canons" that people have created can easily coexist in the same universe. I've always hated the way that the SCP wiki and backrooms wikidot refer to story arcs as "canons". My suggestion would be to start using the word "arc" or "story arc" in place of canon since most of the canons are not mutually exclusive. The word "canon" should only be used to refer to alternate realities that exist independent of other stories; though even these could be viewed as existing in the same multiverse.
