I've thought about it for a while, and I do have some extra ideas or suggestions to put forward for the remaining Fellowships, in case anybody is curious:
If we're okay with doubling on Fellowships, then I do have another idea for Stargaze's last Fellowship.
@Guardian Angel Haruki"___ is consumed by the Isle’s immediate problems; you will show them why they must focus on the future. Take a Friendship Gem from them."
Shieldwing would probably be a good match for this. He is absolutely obsessed with the Isle's predicament, wanting to repel the Darkness once and for all as soon as he can. After all, his entire goal is to get beyond the Cloudstalker, and thinks all of the political teachings he's being forced to learn is a waste of his time because he doesn't need to learn this stuff to combat the Darkness. This could get to the point where he just wants to go out and deal with the problem directly whenever he can.
Perhaps Stargaze, the one he sympathizes with the most regarding this big, dramatic destiny, can make him realize that he'll never make any REAL progress on his ultimate goal if he's just throwing himself at every threat that's in front of him. It's like treating a symptom rather than the more dangerous underlying disease causing it. What if he ends up getting himself hurt in an encounter that didn't matter, and then can't be at his best when his clutch needs him most? Stargaze could show him that just putting himself like a wall between the Darkness and others is only going to cause the Darkness to build up on the other side like a dam, until one day it's just too much and that dam will burst and get washed away with everything else.
Getting Shieldwing to see that there's a right way and a wrong way to do this, especially when they don't even really have a grasp on what the Darkness even IS, could work to tighten their bond a bit more. Especially since he's so concerned about getting past the Cloudstalker in the first place...that he hasn't even really considered what he would actually DO once he got to the surface anyway. xD
Or, if doubling up isn't ideal, then it could be
@BleakBlueJay's Sylph that makes this one work. Maybe Sylph is more obsessed with societal problems, possibly including her own. Maybe it's in regard to problems that this division among Houses is causing or something along those lines?

As for
@Vertigo's remaining Fellowships, the Dream one could apply to basically anyone. But Stargaze might work pretty well for that one, due to Stargaze and Shieldwing being pretty intertwined with one another, so if Fellwing is introduced to Stargaze through Shieldwing along with the rest of the clutch (since Shieldwing is the one bringing her into the clutch), then that could be an "Ah ha" moment for Fellwing as she finally understands who this dragon really was. The actual dream could be somehow vaguely related to Stargaze's destiny as The Orphan?
And if you're looking for a Knowledgeable character for your other one, then Sylph might be your best bet? Shieldwing is definitely not going to fit that mold, and it's possible that Skobeloff might but he seems more of a rogue and trickster type of character than one who would be that knowledgeable. But as a member of House Myndoth, maybe he knows more than he lets on~ Sylph, though, is a former member of House Myndoth, and as a Rebel, has a unique Move that demonstrates superior knowledge of society at the very least and a Shadowself that implies that in the moment, they believe that they know more than anyone else ever could regarding the society's problems.
