Back on my Eldritch Jedi Bullshit
Thinking about eldritch Jedi/Force-Users but not all Jedi. And on the one hand, Anakin being born of the Force and being unbelievably eldritch is good and I like it but on the other hand, Anakin being very powerful but not Eldritch unlike some other Jedi is very funny. See here for a very good version of that.
So some of the Jedi are eldritch. There are faces in their shadows, true faces that aren't silhouettes. There are sunrises and storms and flowers in their eyes. There are more teeth in their mouths than there should be, longer tongues, Power in their voices thrumming along the beats of your heart. There are thorns sprouting from their collarbones, leaves from the gaps in their exoskeletons, ferns from between their feathers. There is sunlight, fire, plasma burning and glowing in their veins, light that can darken into poison, poison that can be purified into sunlight once again. Because Falling doesn't mean you stop burning.
It's tucked away, out of sight. Restrained, much like their emotions. Because when your power reacts to your emotions and you can crush tanks with your mind, it's not physically hard to crush people. They're so much more fragile. The Jedi don't preach self-control for shits and giggles. Sometimes, great power comes with the responsibility not to use it.
And being eldritch it isn't about how powerful you are, though there's some correlation. It's about the way the Force interacts with you. It's the difference between being a channel for the Force and being the Force made flesh.
It's also not something you talk about much in the Temple. It's not exactly a secret, but it's not really the subject of gossip and to people who don't share those traits, it tends to be described as "improving control of one's emotions/relation to the Force." It's personal. Like recognizes like, and padawans with that type of connection tend to get Master's with the same connection. That relationship to the Force makes it easier to lash out, and that's not good for anyone.
It doesn't help that some planets are already leery of regular Jedi. they Really Don't Like the eldritch ones. So over time, this connection became something that was touched on in The Force 101 classes and then not discussed much outside of it by people who DON'T have that connection. Qui-Gon didn't have it, neither did Dooku. Obi-wan doesn't have it, though he knows of it. Anakin Skywalker, as powerful as he is, didn't have it.
Like recognizes like, and most eldritch Force Users know another when they see them. The Jedi make a point, not only of assigning those padawans to similar masters but of taking in those younglings even if they're a bit older than usual. But sometimes, someone just get missed. Sometimes no one sees a youngling's extra teeth, sometimes there aren't any eldritch Jedi in the creche when nightmares scrape the walls, sometimes that connection to the Force is just quiet. Sometimes, that connection to the Force isn't noticed before a Padawan is assigned a Master. Had he known, Yoda would never have assigned Ahsoka to Anakin.
This isn't a slight against Anakin, to be clear. There's advantages to making sure that padawans have masters who know how to help them with their brand of weird Force shenanigans, or at the very least, are regularly meeting with Masters that can help. In normal times, Ahsoka's eldritchness would probably have been noticed within a couple years (if you don't know how to restrain it, it will eventually start showing more) and then she and Anakin would have been introduced to some Eldritch Jedi who would assist with the training. But this isn't normal times. So none of the Jedi notice.
Plo or Obi-Wan could have. Plo's eldritch, and he cares about Ahsoka, but so much of their communication over the war was done over comms. Obi-Wan, having grown up with Quinlan Vos, thinks he knows what eldritch Force Sensitivity looks like and to be fair, if he wasn't distracted by the war he probably would have noticed. But war is Extremely Distracting and Ahsoka's connection is quieter than Quinlan's. He, and Plo, are distracted, and so so tired. So they miss the changing teeth, the periodic gleam in her shadow, the marching beat under her words when on the battlefield that beats in sync with the troopers' boots. And Anakin? He means well and he's trying, but he doesn't know that this is a thing to look for and he can be a bit oblivious.
You know who does notice? The clones. In particular, Kix.
Most all the clones are hypervigilant, thank you Kamino trauma. So they pay A Lot of attention to anything that registers as potentially threatening, even subconsiously. Ahsoka's a kid and they grow to trust her quickly, but there was a time when she was a new inexperienced commanding officer. And after that they were helping to teach her and look out for Threats to the Little Sister, so they were very observant where Ahsoka was concerned.
They don't know enough about Torgurta or Jedi to know what's normal for one, but they do notice the things that don't stay constant. The way her shadow changes, the way her teeth and hands sometimes change shape. Things that are rare in sentients.
Things Ahsoka has started to notice, and worry about.
Kix meanwhile, is a medic who just got an adolescent Togruta put under his care and he has no idea how to take care of her. The Kaminoans weren't told that the medics would be responsible for the jedi (one of those little details that was never clarified and caused confusion in the beginning) so they trained the medics to take care of the other clones and gave them access to some basic medical info for other species for emergency measures. So almost all of Kix's medical knowledge is specifically How to Treat Injuries and Illnesses in Male Humans; Children to Young Adults. Sure, there's overlap, but not enough.
(Yes, the medics do have a private chat where they trade tips and resources and vent about their respective dumbasses. It's a multipurpose chat.)
So he does a lot of research to make sure he can treat Ahsoka properly when she's inevitably injured. He notices things that Do Not Line Up and with Ahsoka's permission reaches out to the Jedi healers.
Now, if eyes might start hovering around your patients when you're doing surgery, that's valuable information to know. So all of the healers know about the eldritchness. They're able to tell Kix and Ahsoka what's going on.
And where it goes from there? I can't say. I can tell you one thing for sure, Mortis undoubtedly makes it WORSE.
