The Lore of Old Yharnam and Blood-starved Beast
(warning editing in progress)
The full story on what happened in Old Yharnam in still being investigated but some parts have already been substantiated.
On the altar there are several golden embossments and the Moon Presence appears in at least two of them.
In the second , she's likewise located in the lower half of the picture and you can once again recognize her trident shaped tails left and right of the picture.
There may exist a connection between The Moon Presence and the Norse goddess Freya.
"Gullveig" is by prominent scholars believed to be Freya. (source Wikipedia: Gullveig)
"She that remembers, the first on earth,
when Gullveig they with lances pierced,
and in the high one's hall her burnt,
thrice burnt, thrice brought forth,
oft not seldom; yet she still lives.
Heidi they called her, whitherso'er she came,the well-foreseeing Vala:
wolves she tamed, magic arts she knew, magic arts practiced;
ever she was the joy of evil people."
This is a second translation:
"The war I remember, the first in the world,
When the gods with spears had smitten Gollveig,
And in the hall of Hor had burned her,
Three times burned, and three times born,
Oft and again, yet ever she lives.
Heith they named her who sought their home
The wide-seeing witch, in magic wise;
Minds she bewitched that were moved by her magic,
To evil women a joy she was."
She has been staked (speared) and most likely burned while crucified. The same happened to the other beasts of Old Yharnam .
The Blood-starved Beast has a face that's still relativily human, that is to say: "not canine".
All over Old Yharnam you can find figures wearing red robes who are strung up and hanging upside down.
Some believe that these hanging corpses are Pthumerians whose blood has been harvested.
In favor of this theory is that the corpses are very tall , but this increased size could also be a symptom of the Scourge of Beasts.
Red as a color is also worn by Graveyard Hags and by the pyromancing Chime Maidens that accompany the One Reborn bossfight.
Red is the color of the "Rotted" buff which can be bestowed by the witchlike Labyrinth Ritekeepers, or by making a "rotted" offering.
Red is the color of the Vilebloods which are also connected to symbols of fire. Red is worn by the Firekeeper Hags of Dark Souls 2.
Pyromancy is traditionally considered heretical in Dark Souls and is connected to witches.
Outside the cathedral you can find pentacles , which are typically associated with witches and also The Devil. (see Tarot Card, The Devil)
This cult may very well have filled the role that the Chaos Witches filled in Dark Souls.
What exactly happened to the cult isn't clear.
They might have stirred up trouble they couldn't contain or they might have been subject to an all out attack by The Choir, or The Healing Church.
In the end Old Yharnam was unsalvageable and left to the beasts. Who benefitted from this situation isn't known.
Djura, the Ashen Hunter stayed behind in Old Yharnam defending the beasts that he still believed were people.
It could be that Djura feels for the beasts because he knew them personally and once called them friends.
It's also possible that Djura sympathizes because he is himself a heretic.
He understands what the beasts are and what they wanted to be. Perhaps he even feels responsible for what happened to them.
Within The Church of the Good Chalice there stands an altar with 3 females kneeling over a dead old man .
Only the middle female is mature, the females at her sides appear very small and young. They are identical in appearance.
There's more to these two girls than first meets the eye. Their faces look like masks and much resemble the ashen cast dead of Pompeii .
The bottoms of their dresses display bizarre curves and resemble lava . That could make them fire versions of The Slime Scholar .
This "lava" resembles the shroud that The Old Man is wrapped in . The chests of the girls also display strange veiny growths (see faces).
Beneath the girls a strange scene is depicted . A large crowd of people has gathered around what appears to be The Old Man's dead body.
In Bloodborne however the apostles do not eat bread representing the flesh of Christ, but the flesh of Christ himself.
Lovecraft himself is also known for using Christian themes and turning them into horrific images.
The females could have been adherents of fire and the Sun, and were likely of some importance to the heretical cult of Old Yharnam.
