So, reading back through some of Legacy's earlier posts, I have an alternate theory for this clue. While I'd love for it to be The Nun/Conjuring, etc, I think there's a more simple explanation.
Legacy talked about being chaotic neutral and also mentioned that there could be answers that are simply clues to the real answer. I think that might be what we have here. He also mentioned that the closest anyone had gotten was step 2 of 5, so I think I can do this in 5 relatively straightforward steps.
Step 1-The Coat of Arms itself is irrelevant except for the "Maria Spes Nostra" banner.
Step 2-"Maria Spes Nostra" translates to "Mary, our hope"
Step 3-The "Mary" in the translation refers to Bloody Mary which is the answer BUT ALSO the clue.
Step 4-In folklore, the appearance of Bloody Mary is predicated on repeatedly saying her name in front of a mirror.
Step 5-You know what other urban legend appears only when saying the name repeatedly in front of a mirror? That's right...Candyman.
So, the answer to the clue provided by Legacy is Bloody Mary. But it is a clue as well to the real/final answer, which is Candyman.
It makes sense since the Jordan Peele Candyman is pretty much, for all intents and purposes, the only property we pretty much know is coming to HHN 30 (maybe not "know", but "highly suspect"). So, it would make sense for Legacy's first clue of the year to be the low hanging fruit of something that isn't a real shocking reveal. Plus, if this is the answer, it could be construed as one of the easier clues he could give (since "Mary" is in the clue itself).
So, I still hope my Nun/Conjuring answer from before is correct. But this one not only seems more plausible, but also a more easily attainable trail of bread crumbs. What do you all think?
