The Noble Circle of Horrorterrors lead the mysterious eldritch creatures that reside in the Furthest Ring. These creatures are getting by Lrd English (as confirmed ), causing them to reach out to Sburb players. They whisper to the dreamers of Derse during the eclipse and have asked both Rose and Dave for help. They serve as a Derse player's advantage, equivalent to Skaian Clouds on Prospit. Feferi's Lusus, Gl'bgolyb, is referred to as an "emissary" to them.
Their current goal seems to be preventing their deaths at the hands of Lrd English, but beyond that they have a mysterious and suspicious agenda, their involvement in Sburb remaining unknown to this day. They seem to be opposed to the creation of new universes (although this may only apply the humans, who created the universe Lrd English was born in), but also to the complete destruction of reality. The horrorterrors are inspired by H. P. Lovecraft's Cthulhu mythos and are in fact referred to as Outer Gods at several points (paralleling Lovecraft's Elder Gods).
On Earth, the Squiddles are stated to be a subconscious re-imagining of the horrorterrors and other Beasts residing in the Furthest Ring, with the character Skipper Plumbthroat possibly representing Lrd English.
- "Squiddles I guess are a sort of candy coated representation of the outer gods. (...) They were not necessarily conjured into existence by the gods, via dark conspiracy either. It's more likely that humans created them as an echo of their subconscious awareness that these gods exist, and present them through this cute, approachable facade."
The horrorterrors are referred to numerous times as the outer gods, leading to the possibility that they are, in fact, the players that created the troll universe, and now exist as its gods. Hussie has , but confirmed nothing.
Known horrorterrors include Fluthlu, Nrub'yiglith, and Oglogoth. Although Gl'bgolyb resembles a horrorterror, she was given to Alternia by Doc Scratch and is really just a lusus in the form of one, in the same way that the other lusii take the shape of white versions of other creatures. Gl'bgolyb appears to have some connection with actual horrorterrors, however, since she helps Feferi convince them to create dream bubbles in the Furthest Ring.
- Main article: Fluthlu
Fluthlu is a creature that appears in Problem Sleuth as well as a horrorterror found in Rose's Grimoire for Summoning the Zoologically Dubious. He is drawn in comparison to a city, which he dwarfs. Even so, he is the smallest of the creatures shown in the Grimoire, many times smaller than Nrub'yiglith, who himself is tiny compared to Oglogoth, smallest of the Smaller Gods. The size of the horrorterrors in the Noble Circle, then, must be unfathomably enourmous.
Fluthlu's name is obviously derived from Cthulhu, though they have few similarities in appearance, since Cthulhu is a biped with wings and Fluthlu appears to be just a blobbish form with various extremities and facial features scattered around his body.
Nrub'yiglith is found in Rose's Grimoire for Summoning the Zoologically Dubious. He is seemingly of a higher order than the better known Fluthlu; a size comparison reveals that, even next to to the already gigantic Fluthlu, he is monstrously huge. However, he is also shown to be tiny in comparison to the "smallest of the Smaller Gods," Oglogoth. He bears a startling resemblance in both name and appearance to Gl'bgolyb, Feferi's lusus (with an equally impronounceable name). His name also bears a (less startling) resemblance to the names of several eldritch beings from H.P. Lovecraft's Cthulhu Mythos, such as Shub-Niggurath, "The Black Goat of the Woods with a Thousand Young," and Yig, "Father of Serpents," as well as "the Twin Blasphemies," Nug and Yeb. This matches Fluthlu's obvious allusion to Cthulhu himself.
It is possible that Nrub'yiglith is the kids' universes' version of Gl'bgolyb, existing somewhere within their universes. However, he may also dwell in the Furthest Ring, serving the Noble Circle of Horrorterrors and their underlings.
Oglogoth is found in Rose's Grimoire for Summoning the Zoologically Dubious. The Grimoire describes him as OGLOGOTH, THE DEEP ONE. Whenever he grinds his teeth, all the children of a random galaxy somewhere will frown continuously for a nine thousand year span. He is the first and smallest of the SMALLER GODS, appointed in servitude of a vile, unfathomable pantheon of MIDDLING GODS which caters to the whims of the Noble Circle of Horrorterrors, an omniscient, omnipotent order of the elite few, forever cloaked in the darkness of the Furthest Ring.
He dwarfs Nrub'yiglith, who in turn looms over Fluthlu, so the scale of this creature is near unimaginable, and he is apparently the smallest of the smaller gods. Good thing the Grimoire is in the hands of a young lady with such a good head on her shoulders.
When a player goes to sleep after their dream self dies, they are free to come into close contact with the horrorterrors via the afterlife. Feferi, due to her positive connection with Gl'bgolyb, manages to talk them into "glubbing up" a series of stabilized dream bubbles that serve as a communication tool between the trolls and the kids, as well as the dead and the living.
As Jack Noir and the prototyped Peregrine Mendicant flew through the Furthest Ring, they seem to be able to come into physical contact with the horrorterrors, but are either possibly unable to interact with them or too busy fighting to concern themselves with them.
On LOHAC, Rose was persuaded by Doc Scratch to ask the Magic Cue Ball if the horrorterrors were evil. The response was (except for the phrase "Oglog M'Rubbit," a ). Upon viewing this answer, she went Grimdark, an uncontrollable and horrifying process described as going completely off the deep end in every way. This physically caused Rose to develop darkened skin, glowing eyes and a thorny black aura reminiscent of the horrorterrors' tentacles, and begin speaking in an incomprehensible language.
During her fight with Jack she seemed to be able to manifest her aura into
This can be interpreted as Rose losing control over the dark magic she received from the Circle. It could also be the result of a sudden surge of power granted her by the horrorterrors. Rose died shortly thereafter and was replaced by her dream self, yet the physical changes were not present on her dream self.
The word "Grimdark" seems to have originated in the table-top game, Warhammer 40,000 and evolved into a memetic phrase.
It is currently speculated that a parallel to this power through the use of a combined cherub Juju is Trickster Mode, as seen when Jane shortly after . While Rose's Grimdarkness is black, frightening, and out of control, Jane's Trickster Mode appears to be the exact opposite, being bright, silly, and even more so out of control. Also as Grimdarkness is , Trickster Mode is called .
Hussie has alsothat Rose's grimdark transformation is meant to complement Kanaya's transformation into a rainbow-drinker, both being absurd transformations granting their characters magic powers that are both silly yet somewhat awesome. This link is, however, merely one of appearance, and Kanaya's being a rainbow drinker is unlikely to have anything to do with the horrorterrors.
- Andrew Hussie has the Alternian universe was played by 48 Squiddles and that he shall reveal these characters and/or kill them soon. It should be noted that the Alternian universe has a suggesting that the Sburb session that created it did indeed have 48 players. However, whether the horrorterrors are the previous players (or the offspring of those players) and creators of the Alternian universe or simply game constructs like denizens and carapaces is yet to be seen.
- Their blood color, as seen in and Openbound, lies between Eridan's and Gamzee's, with the hue being closer to Gamzee's.
