#darklurker

The point is not that Ranni is also a doll! The point is that Renna aka Snowy Crone whom Ranni based the doll's body on, was blue-skinned and four-armed! There is already a whole type of such people, after all:

These guys are cursed, and also dead! Similarly to those with Omen Curse, they are unable to return to the Erdtree as they are "exluded" from the circle of life and death that Marika started! (Mind that this type of enemy is also almost exclusive in Liurnia and that secret Carian place, so, areas that have been hostile to Erdtree until Rennala married Radagon!)

They are, in fact, so cursed that anything holy even if it is a healing spell just straight up kills them dshdsfhd

As for Queen of Latria, I do not have many sources to show just yet (Demon's Souls lore is a hindrance in general until I find how to extract all Japanese script for it, dialogues is the biggest problem to find).

But, the four-armed person was made in likeness of now-defunct Queen that is learned from Soul Ray's description:

It is even more apparent from the textures, too, but she is clearly organic:

This thing is clearly some sort of a demon! I am not sure whether her actual body was used to create Fool's Idol, or it was indeed created from scratch? The look of brown hair (same as what is depicted on the stained glass featuring Queen of Latria) damaged by blue and gaping hole on her back makes me feel like it's closer to the former. But in any case, it is more of a "came back wrong" situation; she didn't seem to have four arms in reality!

In fact, there is a THIRD case of 'four-armed person who came back wrong' in Soulsborne games:

Darklurker is a one of a kind take on concept of 'Angel' that looks not too similar to Angels from DS3 and is the only one to have four arms! They are met in the Dark Chasm of Old, which seems to be what remained of Chasm of the Abyss! Granted, it isn't even on the same continent; it is literally accessed through portals, and Nashandra is stated to have arrived from overseas!

Moreover, Darklurker is unique amongst angels as they literally split, not unlike it happens with rare Twin Humanity! It isn't a common trick for a Soulsborne boss to just create a fake version of them, it is literally the same boss twice now.

Considering what Dark Chasm of Old is, and that Angels sprout from within the strongest concentration of darkness in a human being, I'll tell you more; Darklurker might be another, secret part of Manus! It isn't himself, of course; Darklurker is as much still Manus as any angel from Dark Souls 3 is still the person they sprouted from. But you get the point!

Naturally that his version of Angel is absolutely unique because Manus was unique; the only person in the setting with a pitch black soul even darker than those of Gael or Midir, the only dark being powerful enough to be reborn as four whole new Dark beings, the only person in the setting who literally radiates darkness by Just Standing There and produces Humanities, the master of the Abyss and not just someone living in there... Also most likely not human but Pygmy, because his mutation was very similar to that of a mad Pygmy king that Shira "killed" (he didn't fully die tho):
