Interesting things I noticed in Ariandel
The Crow Talons' description mentions "five perpendicular slashes," which seems like an error (should perhaps be parallel) or an intentional reference to crosses*
The Japanese description uses "五列" meaning five lines/rows/columns. Interestingly, it seems like a reference to the term "fifth column," which refers to an internal enemy undermining a system, like how the Corvian Knights slaughter their own brethren.
This also brought to mind the four pillars of Lothric, and how Sulyvahn might have promoted a "fifth column" through the Angelic faith.
Most interestingly, I discovered that the middle phase of the Friede fight, "Father Ariandel and Friede," has initials FAF, which are equivalent to 616, the oldest recorded variation of the number of the beast. The "antichrist" imagery reflects how Friede is a false version of [Cross]breed Priscilla, and it's notable that the murals in Ariandel's room depict a serpent, echoing Genesis. The Titanite Slab at the end of the phase represents the Logos, or Word.
This is interesting as "Fire and Ice" is Robert Frost's poem based on Dante's "Inferno" (GRRM's "A Song of Ice and Fire" is named after it, and Elden Ring seems inspired by another of his poems, "Nothing Gold Can Stay"). Traitors are said to dwell in the 9th circle of hell, frozen in a lake of ice. Friede is a traitor to Londor and the Forlorn.
(Before anyone calls the 616 point a stretch, let it be known that Undead Legion of Farron also spells ULF, meaning Wolf.)
*There's precedence for references to crosses, as the paintings are the home of the crossbreeds, Vilhelm says, "curiosity could be your cross," and Father Ariandel is hidden behind a cross-shaped crank. The Farron Followers are also associated with the Crucifixion Woods. In Ariamis, there was the "annex" key, the wheel-cross skeletons, the Xanthous King, the Phalanx, and Priscilla was behind a cross-shaped crank. (I'm sure there's more that I'm missing)
Tl;dr - Crow Talons have a weird item description, Ariandel contains a bunch of references to Christianity.
Edited - bulked out paragraph 5
