: It's not good to have those things in separate places,
: for it's helpful to have theories of varying degree
: next to the singular truth, the theories clearly

Delusions articles are always lists of certain truths, and then extrapolations from them. I didn't just say "I think the Spider Gods are the Dark/Old Gods and the Fetch and Callieach and Spider come from their world down the Great Devoid", etc. I gave a whole bunch of facts, pointed out connections between them, and THEN came to a final conclusion.
So if you're just writing a list of facts, like a bestiary, then it's a Relics article. If you're writing a History of Myth, based off of known facts and extrapolating the rest, it's a Delusions article.
