Well as the title of the chapter suggested that escalated quickly. I'm glad you could update again, Legion is a pretty unique choice for a familiar.

[Rough Scene 1]
Legion: "Religious dependency often leads to social stagnation."
Louise: "You better not say that near a servant of" the Church of Brimir, or else they would see you burned."
Legion: "This unit is highly heat resistant."
[Rough Scene 2]
Legion: "The humans we are familiar with have long since mastered space flight, yet some of them are still willing to believe in a higher force, such as God, a conceptual being who is identified as the personified embodiment of omnipotence."
Louise: "You must have encountered lots of various individuals, have you not?"
Legion: "Indeed we have."
[Rough Scene 3]
Legion: "Some would say that magic is simply an advanced form of science that people does not have a proper understanding of."
Louise: "Does that mean you do not believe in magic?"
Legion: "Contrary to humans' belief and opinion regarding the subject, we do not intend on using that metaphorical perspective as an excuse to justify a supposed nonexistence of magic. In fact, we would rather use it as a way to better adjust ourselves to environments related to, as well as based on-and-around, sorcery."
Louise: "Have you ever encountered a man or woman of science who used that kind of understanding?"

I like where this is going. Seems it's not just a rehash of FoZ with [insert xover character here].

Please sir, may we have some more

Not bad, but definitly noticeable you're working off fanfiction for ZnT. Normally this annoys me quite a bit but in this case it's excusable because ZnT really is pretty bad. Just know your using some fanon. You also have a rather cracky interpretation of Louise but in reading this as low level crack anyway so it's tolerable.

As for the actual writing, mostly good for fanfiction but you have a bad habit of adding extra detail by going, "perhaps is she had". Statements like that break the narrative and 99% of the time the information in them is unnecessary or could be better included in the actual chain of events through show don't tell. I'm mentioning it so you can try and hammer that out of your writing because I do similar things from time to time and it's almost subconscious in how you want to write, you need to get into the habit of not.

If you dissapear for mounts again after this, I will tell quarians where to find you. But chapter is cute, even with a corpse in the end.

Wonder if when the fight with Guiche happens legion will kill him with a shot tot he head

Flame! Noooooo! Why! Why! Take me instead! Honestly though, it kind of deserved to die at least once after 999 offenses of dragging poor otherworlder's into Kirche's bedroom. I mean, it IS a fire lizard 'attacking' you. Why wouldn't you kill it?

Jokes aside, welcome back. I almost forgot this existed.

More plz

I shake my fist at you for the cliffhanger

Poor charmander. It’s the first time I’ve read a familiar that using summoned by Louise get hurt

Haha yes! It lives!

Aw but I wanna know D: I'm invested!

So it's well written, not giving the finger to either universe, and is of a decent length. A really good foundation for the story so far. Very interesting interpretation of the familiar runes interacting with the Geth collective, and the Legion POV was a wonderful source of fish out of water humor. The massive "We really aren't on the same page, in fact I think we are in separate books." conflict between Louise and Legion is both compelling and humorous. The issue I have is there isn't enough of it. While internal monologue is important for the 1st person perspective, and you successfully convey what your characters are feeling and thinking. But there is just way too much of it. Brevity is the soul of wit, and the massive blocks of Louise's inner monologue coupled with overly elaborate descriptions of events that do not serve the story.

An example would be in part 3, when a teacher enters the dining hall to announce the theft of the staff of destruction. The sentences "Why? Well suffice to say...things in the initial...was an announcement" is a good example of what I mean. The relevant information in those few lines is "A teacher entered the dining hall, which quickly fell silent, and made a troubling announcement", all the extra description is empty fluff. How the room quiets down is irrelevant the story, nor is it a critical detail or complex situation. The reader can, and with the normal level of detail already present in this story, fill in the details themselves automatically. Ultimately this leads to a really long and sometimes boring gap between your conflict/dialogue/action.

The aforementioned story elements are the "main event" of most stories, yours included. Which is good because your dialogue gets a solid A from me so far, but I digress. The inner monologue and expository text is the path that we walk to get from set piece to set piece, where we enjoy the set up conflict and character interaction. Your path is long and winding, and invokes a feeling of "Just get on with it already!"

Really wish we got a Louise-Legion dialogue scene after the magic vs barrier experiment. Cut down on the long winded exposition and try to focus more on your character interactions. If a description isn't relevant to the main idea of the story/paragraph, let the reader fill in the blank and just get back to the interesting stuff.

Did Legion had a Geth Pulse Rifle? Which is basically a pseudo plasma gun? which is kinda a step up from normal CC guns and really deadly to both Shielded and unshielded opponents?
