Well, that's certainly interesting... Let's take a look at Salem's Legendary Grimm, or whatever the members of her Council are.
Three avian figures, one with a large hairline fracture that circles its mask, are settled in a forest clearing. Occasionally, they flicker in and out of view so quickly that they simply appear as blurs. When they do so, they generally come back with spatters of blood on them.
The Furies as they are referred to, with common mythological references to the trio of referred to as 'Erinyes' or 'Dirae in Greco or Roman Mythos respectively. There are three common members by the names of Alecto who symbolizes implacable and/or ceaseless anger, Tisiphone or Tilphousia who symbolizes vengeful destruction, and Megara who symbolizes jealousy and envy in the throes of rage. While we lack more information on them to draw any meaningful conclusions, it is a possible source of correlations for the future.
A single blood-red eye, so large that it takes up the entire view of the screen.
While referenced later, I believe that this is the Jabberwock, most bestial of the ancient Grimm in Salem's view. A titanic Grimm Wyvern, and if it's following any typical depictions of draconic entities, one that only grew in power with it's age. What it may lack here in seeming intellect, I would be very surprised if it did have a level of cunning to it.
A creature that seems to mirror Salem in stature and grandeur- sitting with legs crossed, head resting against a single bony finger. However, its throne sits in the middle of a dead, blackened forest, in the ruins of an ancient, overgrown city. A simple rod of blackened yew sits next to it, strung with ancient fibre that holds a cruel-looking hook on the end.
The Fisher King, and as someone who got to this before me mentioned, a trope in and of itself. Typically defined by complete personal control of a local reality defined as their 'kingdom', this link often extends both ways. Corruption of the land would also corrupt the Fisher King, and healing of the Fisher King could restore health and vitality to the land. With a Grimm in such a role, and one sentient, the Fisher King is likely a force both unstoppable and unmovable without their personal consent, within methods that they are aware and in control of.
A simple mirror in a dusty room, only reflecting the Seer.
While I have my suspicions, my mind keeps drawing comparison's to the idea of the man in the mirror. Considering Salem's near pity for Lionheart suffering it's attention, I would not be surprised if this Grimm is in fact quite similar to that concept. Who better to break a man, than the man themself? Who better to whisper words of corruption, deprecation, than one who moves with you? And when you cannot determine whether you are speaking the words echoing in your own voice, well, I would wager that would be quite detrimental to your own mental health.
If the Grimm retains any abilities beyond that linked to mirrors, it would be a slippery agent and peerless infiltrator indeed.
A great, black tower, only barely resembling a creature, with mile-thick cables that extend high into the sky above, and deep into the ocean below; an ocean which boils in its very presence. That Seer is rigid with pain connecting to its tortured sibling.
Ah... Where do I begin? When the earth has been harvested bare, and seas boil with the emissions of that light which the eye cannot visualize, and even the darkness is but a fleeting memory as sparks of information are contained within it's chasis... The Tower is not nature. The Tower is what lies beyond, where the avarice of progress untempered by respect for that which spawned it. All is a resource, a variable, and for that which it can quantify, it can compute. The Transistor's mortal counterpart one might say, forged of destruction and ceaseless in examination.
Somewhere else. Somewhere not Remnant. Somewhere only filled with purplish-black mist and not much else. Salem chooses, quite pointedly, to not focus on that one.
Oh, hello
ElderOuter Old Gods things from beyond this World. Or at least something that Salem really doesn't want to contemplate. This is probably not something to be worried about, and without further information, will not be analyzed in this post.
Alright, so, we don't have all thirteen. From what we do know though, Salem's peers are mighty in their fields. Them having encountered the Process, in all likelihood through The Tower, and Lionheart being under assault are not good things. As others have already said though... Do not assume that hope is lost yet. Though Salem and her forces are varied and multiple in both might and methods, that is no reason to doomsay our inevitable loss.
Now, the final thing that interests me, is Ivory. As others have pointed out, he is a likely expy of a character from Transistor. And for him to be working with Salem is not a good thing. A saving grace is that he appears to function more as a gadgeteer and networker, and Salem also didn't treat him like a plaything. Granted, treating him like a resource to be directed isn't much better, but she did appear to actively value him. So while Ivory isn't a direct threat yet... I'm inclined to believe that he is likely a part of Salem's human side operations, in a manner that she hasn't shown anyone in the show to have. Do not underestimate someone who is valued the way that Ivory appeared to be, especially if they have a Semblance or just pure mental skill that strikes me as very similar to Jaune's own Calculation.
Overall, and in the same vein as the Boriah Lee interlude, this one was excellently written with plenty to parse over and analyze.
