Hello Arka, here starts my oddisey ^^
On average comment, I'd say that you haven't lost your flavour, the writing has still that freshness that could be seen in part 1, and its language makes it accessible for everyone.
This time, though, you've faced a big challenge, this one being having parallel stories going on.
It's not an easy thing to handle, and, certainly, timing has not aid you. Still, the effort was big, and I do not think I'd have done it any better, this difficult I consider the task.
At times, we've: Zorbels+Arka, Sudisir, Nikoren+Pinante, Gholmyyr, Lordbug jailed, Rabartus+Finara, Jefecra, and finally "K" plotting. This makes 8 parallel "live" stories to tell, not an easy task. In fact... might be too difficult. Normally, you focus on one story each chapter, there are times when you've put two of them, but, generally, you're focused on only one. This I think, might have caused some confusion. Forgetting what other characters are doing, since it's a long period of time before they take part again in the story. I do not know how you could have minimized this, perhaps advancing less on one story per chapter, and doing the half of the way, but on two stories, rather than only focusing on one... but that's not always possible because you need certain things to happen in order to make relevant (worth to be told) the other's actions. You see too, that I'm not very good when it comes to make short posts, so I'm certainly not the best one to suggest how you could have improved that.
In any case, I promised to reread the story again, and this is what I'm going to do, I'll leave you comments regarding each chapter (if only a line) so, let's start:
Part 1: PrologueBefriended by the menkie, Lordbug, she tracks down the evil dermorian, Sudisir, who had...
Ok... normally people refers to them as "menki" IIRC, in any case, the first comma shouldn't be there. Yes with Sudisir name, that has to go sorrounded by commas.
of her village and the death of her clansfolk
I'm wondering if it should be "clanfolks"
After an epic battle, Sudusir
Sudisir

her mother?s work; translating the epics and sagas of her people, the Stonebreakers and creating a dictionary
Yeah, it's mother's but the point of this is that I think that you should have added a comma "people, the Stonebreakers, and creating..."
University of Yliakum
I'm aware that the KS have a university where they teach their guildmembers and such but... is it really called Yliakum University? Sounds a bit too big. That would mean the university in the whole stalagmite. From the writing I'd say that the university is settled in Hydlaa, thus it perhaps should be named Hydlaa University? In any case, in the official setting there's, too often, a confusion going on calling Hydlaa city Yliakum... so I guess it's not entirely your fault :S
and Arka?s troubles were far from over
should be Arka's...
Real comment:
After all that unnecessary babbling, the overall comment of this chapter is. Thanks! When someone writes, has to think about the readers. You did that with this "prologue". Aware of this story being placed in a new thread, you did not only refresh the memory of those that read the 1st "book" in order to settle themselves in the action, but also introduced the fact that there is a previous written story, for those readers that were completely new to the story.
This background, even if not falling into little details, gives the basis as to understand the action that develops on the coming chapters, and it's certainly such a gesture that you had towards the "community". So:

Part 2: A new lifeAnother of your traits can be seen in this chapter. Sense of humour. You added some in the 1st book (Arka taking a bath upstairs at Kada Els comes to mind... no that's not the joke you made, it became right after that, but I cannot recall exactly, I just know it was put after that ^^) and here you put it with how the battle is amplified by the population. It's subtle, but at the same time real, and it gives believing to the action that Arka did, as it has formed part of the global memory (even if altered ^^)
This fact makes Arka feel uncomfortable, and its very well used as a reason (one more) for her to accept living inside the university, even if the room needed some fixing (is the university that overcrowded?

I guess you simply wanted to show us a determined Arka, making the room hers, cutting the chairs and tables to her size... another nice detail in there, by the way) but the fact of introducing all the "noisy", disturbing for Arka legend around her, adds to the reader's belief of Arka wanting to be away, and have some period of calm.
Those facts also introduce us to Arka's way of being, a humble dwarf for one side, but also determined, as she doesn't hesitate to adequate the room for her.
All and all, a great chapter, if the first settled readers in the story, this one settles them in the character.
Part 3: A visitorhad been busy sketching when there was a knock at her door. She started
should be "Startled"

They stared at each other in silence. Pinante understood. Her arrival in Hydlaa had opened up the grief he felt too. And the guilt. If they had got back to the village in time? But there was no use feeling remorse. It would not bring his friends back.
He broke the silence. "Aren?t you going to invite me in?"
Very pictorical image you wrote in here Arka, one can just see Pinante standing on the doorway, and Arka in front of him both lost in the same thoughts. If only, to add more to that feeling, right after this first paragraph, you could have pictured Arka looking a bit down, remembering, and being "awaken" by Pinante's question.
On average, the chapter's fine, and, through the action, you let the reader imagine the physics. You hardly describe facial expressions or gestures, tend more to the sentences or actions the chars are doing, also adding at times the tone of voice. Although with that, you certainly achieve a complete "picture", it would not be wasted effort to, now and then, try to explicitly state some face reaction, for instance.
In this particular chapter, we see a shy Arka, that on her retirement thought about her lost home, and pictured on a blackboard her plans, that she covered with a sheet, even if she was the only one in that room, and expected no visitors.
In that sense, the irruption of Pinante, even being a close friend to her, is such a surprise and an unexpected event, that is like a tornado looking all the room, and touching all items. While Arka's reaction to all of that, can be extracted from the dialogue lines she has, you could have added a bit more of detailing of her embarassement, being overrun by the entrance of Pinante, for instance you could have pictured her always standing still in one same spot (how I pictured her) watching how Pinante went from here to there, how she was curious about the blackboard... you could have then make her make a step forward, as if trying to stop him, but, shortly after, making a step backwards, unsure of what to do or how to act.
As a last praise, I'd like to say that it's specially enjoyable to see how you managed to build a story, non unsubstantial, but that describes your char way of being with a certain depth, and all of that without moving from location, standing always inside of her room at the university attics. I guess that's not an easy thing to achieve
