      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.

                    Rom, Ebrietas, and The Celestial Emissary are all created, making them not true great ones, while Amygdala, Mergo's Wet Nurse, And The Moon Presence can only be fought in dreams and nightmares, and are not kin, but great ones, plus grant the NIGHTMARE SLAIN prompt at death

                      This is definitely inspired by HP Lovecraft's work. Cthulhu and his buddies. Cthulhu himself is one of the Great Old Ones although above them are Outer Gods.

                        This is wrong. Great Ones are defined as having ascended to a higher plane of existence. Ebrietas and Rom were "left behind", implying that she did not ascend, and the celestial emissary was created by the choir as a medium between them and the great ones. This is confirmed by the fact that all three of these characters are considered as "kin" by the game, whereas Mergo's Wet Nurse, the Moon Presence, and the Amygdala are not tagged as "kin".
