This was supposed to be titled "The Namesake," but I just had to open my big mouth to Grigori and mention that I was tempted to call it "The Namesnake," and then he wouldn't let me back off on it. If a pun passes Grigori's filter, I know it must be good.
Neither Dr. Michael Nass, who is fictional, nor HarryBlank, which is a pseudonym, wrote the Wikipedia article on Tiamat. That was, however, actually a quote from it, which can be found (in the lede, amusingly enough) here.
