What are the Great Ones, and what do they want?Fiction

In-universe lore. Claims are judged against the fiction's own canon, not the real world.

The Great Ones are Bloodborne's eldritch gods, the higher beings the scholars of Byrgenwerth and the Healing Church spent lifetimes trying to reach through blood, insight, and ritual. Their own item and rune descriptions say more about them than most players notice, yet leave their deepest motives to cosmic-horror ambiguity.

Established 8supported, uncontested

  • Within Bloodborne's world the Great Ones are the higher beings, the eldritch gods that the scholars of Byrgenwerth and the Healing Church revered and tried to reach; wikis that collate the game's text describe them as extremely powerful, multi-dimensional beings that exist across several planes and are often called gods.▰▰▰▱▱ likely2 points

  • The game does not present them only as monsters: the Moon Caryll rune, gained by making contact with the Brain of Mensis, states plainly that the Great Ones inhabiting the nightmare are sympathetic in spirit and often answer when called upon.▰▰▰▱▱ likely2 points
    Supports
  • A refrain runs through the game's key items: every Great One loses its child, and then yearns for a surrogate. The four One Third of Umbilical Cord descriptions repeat this line, framing the Great Ones' grief and their search for a replacement child as a driving force behind the events of Yharnam.▰▰▰▱▱ likely2 points
    Supports
  • Insight and blood are the media that bind mortals to the Great Ones. Insight is the game's measure of inhuman knowledge, and raising it lets the Hunter perceive what is normally hidden, so that Lesser Amygdalae become visible clinging to the Cathedral Ward's buildings at 40 Insight and a Great One infant's cry can be heard at 60; blood is the Great Ones' own medium, and the Formless Oedon rune calls the oozing blood the essence of that formless Great One.▰▰▰▱▱ likely3 points
    Supports
  • The Moon Presence is the Great One behind the Hunter's Dream. The Third Umbilical Cord description says it precipitated the encounter with the pale moon, which beckoned the hunters and conceived the hunter's dream, and, on the wikis' reading, the Moon Presence used the first hunter Gehrman as a surrogate host to create that Dream and keeps him bound within it.▰▰▰▱▱ likely3 points

  • Ebrietas, Daughter of the Cosmos, is a Great One kept by the Healing Church. Wikis describe her as an optional Great One boss found prostrated before the Altar of Despair in the Upper Cathedral Ward, the being the Church's inner Choir made contact with through the Great Isz Chalice, and then left behind there.▰▰▰▱▱ likely2 points

  • Kos, or some say Kosm, is a dead Great One whose carcass washed ashore on the coast of the Fishing Hamlet. The Kos Parasite weapon records that when the carcass washed up its insides were teeming with tiny parasites, and Byrgenwerth's scholar-hunters desecrated the corpse, killing her unborn child, whose Orphan later emerges from the corpse to be fought as the final boss of The Old Hunters.▰▰▰▱▱ likely3 points

  • Mergo is an infant Great One, described as the child of Yharnam, Pthumerian Queen. The School of Mensis used a Third Umbilical Cord to gain audience with Mergo, which the cord says resulted in the stillbirth of their brains, and the Great One Mergo's Wet Nurse is only Mergo's guardian, not its parent; after the Wet Nurse is slain, Queen Yharnam bows in thanks and vanishes.▰▰▰▱▱ likely3 points

Disputed 3credible sources disagree

  • How much of a Great One Oedon really is stays contested. The Formless Oedon rune flatly calls it the Great One that lacks form and exists only in voice, yet unlike the embodied Great Ones it has no body at all: some read it as the most transcendent of them, while others treat a bodiless voice that works only through blood as barely a discrete being, more an influence than a Great One in the same sense as Kos or Ebrietas.▰▰▰▱▱ likely2 points

  • Which beings truly count as Great Ones, and which are Kin, is genuinely unsettled. Kin are said to be humans or beings elevated by contact with the Great Ones, but several powerful bosses blur the line: wikis file Ebrietas, Rom the Vacuous Spider, and the Celestial Emissary as Kin Great Ones, Rom is called a Great One boss yet drops Kin Coldblood, and the Celestial Emissary looks identical to the lesser Celestial mob it hides among.▰▰▰▱▱ likely3 points

    • There is a certain amount of confusion surrounding what constitutes an original Great One and how to distinguish them from Kin. This stems from the fact that several Kin bosses have tremendous power and abilities that can be considered to be "god-like". Due to the fact that both have an alien appearance, it becomes hard to determine whether one was an original Great One, or an extremely powerful Kin that later became a Great One.Great Ones - Bloodborne Wiki (Fandom) analysis
    • Rom, the Vacuous Spider is a Great One Boss in Bloodborne. She is a Kin-type boss and drops Kin Coldblood (12).Rom, the Vacuous Spider - Bloodborne Wiki analysis
    • Celestial Emissary is an optional Great One Boss. During this fight we see a crowd of Celestial Mob with the Celestial Emissary, which looks exactly like the other Celestials, hiding between them.Celestial Emissary - Bloodborne Wiki analysis
  • Whether the Moon Presence is a benevolent guardian or a predatory master divides readers. The Plain Doll addresses it tenderly as O Flora, of the moon, of the dream, and it grants hunters the Dream and the power to revive; yet it is also the being that keeps Gehrman imprisoned, used him as a surrogate host, and, if the Hunter refuses Gehrman's release, descends as the game's true final boss to claim the Hunter as its own.▰▰▰▱▱ unlikely2 against3 points

Debunked 1refuted by the evidence

  • The common framing of the Great Ones as simply the malevolent villains of Bloodborne is not what the game's own text supports. Catalogues of the game's antagonists list them as its main antagonists, but in-game the Moon rune calls them sympathetic in spirit, their overriding motive is grief for a lost child rather than hatred of humanity, and lore writers note they do not actively seek to destroy humanity.Refuted byThe Great Ones that inhabit the nightmare are sympathetic in spirit, and often answer when called upon.refuted3 against4 points

Unresolved 2no settled answer

  • What the Great Ones ultimately want, and whether they are benevolent, indifferent, or beyond human morality altogether, is left deliberately unanswered. The clearest glimpse is that they seek a surrogate for a lost child, but their larger aims are described only as unknowable, a withholding of the answer that is a FromSoftware signature also seen in the sibling questions on Dark Souls' First Flame and the Greater Will versus the Frenzied Flame in Elden Ring.▰▰▰▱▱ likely3 points

  • The meaning of the Childhood's Beginning ending is left open. If the Hunter consumes three One Third of Umbilical Cord, refuses Gehrman, and defeats the Moon Presence, the trophy states the Hunter became an infant Great One, lifting humanity into its next childhood, appearing as a small slug-like creature the Doll cradles. The game confirms a human can become a Great One, but whether this frees Yharnam, merely installs the Hunter as the next Moon Presence, or restarts the same tragic cycle of a Great One destined to lose its child is never resolved.▰▰▰▱▱ likely3 points
