Lots of well known music groups getting together and performing in the span of only a couple days.

And from what Raidou tells me, they're looking for an escaped shapeshifting alien. Despite our best efforts, some of us are fairly suspicious. [He sounds rather dry when he says that - there may have been kidnappings, but he doesn't seem overly concerned about them.]

It's strange for me too. We didn't really have musicians in my world - or at the very least, not outside Wall Sina.

And no, we're not. As individuals, some of us can be. But as a whole, we are very much lacking in terms of blending in.

Ah - back home, what's left of humanity lives behind a series of three walls meant to keep our predators out. Well, we did until 5 years before I became a Traveler, when the outer wall fell. I was there when it happened - the poorer people always live further out, closer to the outer wall.

Wall Sina is the innermost wall. All the nobles and well-off merchants and other rich folks live in there. [Getting fat while the poor work themselves to the bone and all but starve anyway, even the children.] Whether they have musicians behind Wall Sina, I couldn't say. I just know that there aren't any outside it.

...Are you alone? I could show you, if you want, but I wouldn't want to alarm anybody else. [Technically, he could probably make it so only she could see it, but he hasn't tried before, and this isn't the ideal situation to test it. Plus, she might like to be alone before she reacts to the titans.]

A fair number do, many simply from societal pressure. Within a certain group of people, you're often seen as a coward if you don't join the military - at least, that's been the case since the wall fell. But even those who join on their own rarely do so intending to fight titans.

Only the top 10 soldiers in every cadet corps can join the military police - they're in charge of protecting the king and maintaining the peace in the inner cities. It pays better and is more prestigious than the other branches, but it's sought after primarily because it means they get to serve inside Wall Sina, where a titan attack is least likely.

The Garrison is by far the largest branch. Anyone who graduates the cadets can join, and they are tasked with the defense and upkeep of the outer walls - just Wall Rose, now. More dangerous than the military police, certainly, but they'll still only have to fight titans if there's ever a breach in the wall, and that's only happened once.

And then there's the Survey Corps. We are the only ones who normally expect to fight titans. We are the ones that go outside the walls to try to discover the truth about titans, and work out how to defeat them. It probably won't surprise you that we're the smallest branch of the military - both because of how few volunteers we get, and because of how high our mortality rate is.

All right. I'm going to project them for you now.

[He knows she's seen a lot, but he still wants to warn her before throwing something like that at her.

The image of a titan appears beside her, ten feet tall. Its arms are small and misshapen, and it's frozen in mid stride.]

This is a 3-meter class titan, about as small as they come.

[Another appears beside it, similarly deformed - head grotesquely lopsided and oversized, nearly 25 feet tall.]

This is a typical 7-meter class titan.

[Armin's tone is serious and intent, but calm. A third titan appears - this one more than twice the size of the last one, standing at least fifty feet tall. Like the others, it is frozen in a curious stance, head raised and mouth gaping - the reason, of course, being that these are all titans he's seen himself, pulled from Armin's memory.]

This is a 15-meter class titan - the largest and most dangerous of the common ones seen in battle. But there are exceptions.

[And then a true monster appears - unlike the others in more than one way. It stands fully four times the size of the last at two hundred feet tall, and lacks skin, its bone and muscle exposed.]

This is the Colossal titan, standing over 60 meters high - it destroyed the gates of my childhood home and, with two others, drove humanity to abandon nearly half of its territory, fleeing behind the safety of the second wall.

I have also heard from others from my home world that there is a 120 meter titan, too large to even support its own weight.

[There's a complicated explanation that Armin would get into if he was asked, but talking about titans never really gets him in a terribly sharing mood.]

...I've seen many of my friends and comrades die trying to find the answer to that question.

[There's a fair pause, where he acknowledges her sympathy, but doesn't seem to have anything particular to say about it.]

...Are they very powerful? [After all, you could be much, much weaker than a titan and still prey on humans.]

Are they a threat to humanity as a species, and not just individuals? [Because having a predator and having a predator that threatens you with extinction are very different things.]

I see. [That's fortunate, in a way, though that's not something Armin would say to her aloud.] ...Your organization sounds a lot like my government, back home.

There's some intelligence behind the titans and their attempts to eliminate humanity - it doesn't show on an individual scale with the titans. But there are titan shifters, people who can turn into incredibly powerful titans like the Colossal Titan. They're the ones who broke down the outer wall and lead the titans inside. But they come from outside the walls. We have yet to learn their secrets.
