      This page is so wrong. The Great Ones (Elder Gods) are as follows: Rom, Ebrietas, Moon Presence, Mergo, Kos and the Nameless Vileblood Source. Amygdala is no Great One and is in fact never called one in the game. I'd more easily call them a Kin of Rom. Personally I separate eldrich enemies into three categories in this game: Kin, True Kin and Great Ones. Kin are your average run of the mill eldrich abominations. True Kin are specifc creatures of which every Great One has a single instance of: Mergo's Wet Nurse, Orphan of Kos, Rom's Dream Attack, Ebrietas, DAUGHTER of the Cosmos, Bloodletting Beast (Nameless Vileblood Source). The only exception is Moon Pressense because YOUR CHARACTER is PART of the Moon Presence. When you "kill" the Moon Presence, you're just playing your part in the cycle, becoming the next iteration of THAT Great One. YOU ARE THE MOON PRESENCE. To anyone who doesn't understand just good Bloodborne does its elder gods, I beg you, please read this, then analyze the game itself. The best part? Some Great Ones even show themselves. The Altar of Despair? That's Rom hanging out. That LAKE behind The Orphan of Kos (Which, guess what, you're actually fighting Orphan of Kos 2 born out of another dead True Kin, the corpse). THE LAKE is KOS! Mergo? You're literally STANDING IN HER NIGHTMARE Mergo's not a goddamn invisible baby this isn't Dark Souls. The Elder Gods are concepts in this game. They're UNKNOWABLE. I know I might sound pretentious spouting all this, but I know I'm right and I have to tell everyone because it's JUST SO GOOD. This game is Elder Gods done right. Ignore this page. You don't get anywhere near to touching an Elder God this entire game. Don't let people try to fool you. The only thing you ever do is sever your connection to Great Ones, which doesn't matter, because you're already fated to remain connected to the Moon Presence. That's an entirely different tangent too. Watch the cutscene at the start of the game. Two Great Ones interact with you there. One is Ebrietas, taking the form of a beast, which "lends a peaceful hand" to you before being BLASTED by the Moon Presence who CLAIMS YOU. YOU HAVE NO POWER. THE GREAT ONES JUST FIGHT OVER WHO GETS TO KEEP YOU. Abrietas gets you? You turn into a beast. Moon Presence gets you? You turn into a Hunter. Kos gets you? You get transferred from Moon Presence to Kos when you go crazy from the beastblood. Everything in the dreams is owned by the Great Ones. It's insane the lengths this game's devs went to make their Great Ones make perfect sense. It's just absolutely beautiful.

          Amygdala isn’t a great one. Every great one is unique and their are loads of amygdala. Same applies to celestial emissaries.

            I hate how our charater eats up GODS like they are some sort of killable entity that doesn't destroy worlds, I guess it is inspired by lovecraft not made by him.

              I just noticed master willem's blood is white (maybe almost clear) ... Does that mean he's close to anything of kin or great one...?

                Is Mergo’s Wet Nurse really a great one? Because after you kill the Moon Presence wich is a great one the « Nightmare Slain » line appears immediately unlike The Wet Nurse, which comes a bit after. My theory is that the Wet Nurse isn’t a great one, but a really powerful enemy that is ordered to protect Mergo the infant great one, by Formless Odeon, and in the end of the nightmare of mensis what makes the « Nightmare Slain » line appear is that during your battle with the wet nurse, Mergo is killed or hurt really badly and the line only appears not after the death of the wet nurse but when Mergo’s cries are silenced

                  *SPOILER WARNING*

                  Are Rom, Ebrietas, and the Celestial Emissary (and arguably, perhaps even the Moon Presence) true Great Ones? Or are they ascended Kin of the cosmos?

                  My impression of the Orphan of Kos is it is NOT a true Great One, simply because it is only a shade/specter/ghost of the Great One it could have been—had it not been dissected/slain in the waking world by the Church.

                        Is Mergo's wet nurse 'Oedon'? Formless Oedon is mentioned quite a bit while 'Mergos Wet Nurse' isn't the creature's actual name but a reference to the function it performs for the 'child of a great one' Mergo. The wet nurse is also...well..formless - or at least mostly invisible.
