The Colossus passed by a lake area not long after we took off. At that time, we saw something gleaming by the lake and thought someone was trying to catch our attention with a light signal. Upon closer investigation, we realized that was an elegant and beautiful girl in a white dress checking herself out in a mirror. When she looked behind her after noticing that we were watching her, we were all shocked when our eyes met. Now that I think about it carefully, given how big the Colossus is, it would actually be more difficult to not notice it passing by.
By chance, Ms. Nikinis joined us on the Colossus later on, and I heard it was to find her lost memories. After she arrived, our first impression of her was that she was a mysterious and unapproachable existence. There's even that observation incident... Sigh, I think it's more difficult than ever to strengthen the relationship with her.

I live at Lake Mirror before coming to the Colossus. It was quiet and pristine, much like the lake where I first encountered the Colossus. It had never had a single ripple, no white deer had ever drunk from it, no snowbird had ever skimmed on its surface, no falling leaves or tracks had ever contaminated its depths. The towering rocks blocked the light and heat from the sun, and the lake was surrounded by perennial snow. The lake was like a mirror embedded in white snow, and it looked untouched by humans. I could sit there, day after day, as long as I'm with my sister.
However, since Her Majesty has assigned me a new mission, I must complete it. There is no other reason for me to come here besides that.

Do you like white flowers? White lilies—yes, these are white lilies sent here by my older sister, Nepolis. If you like them, I can let you watch them from the distance for a while.
You must have noticed the existence of my sister. We have always been together since we were born. She doesn't like to talk to strangers, so she usually stays in the mirror. Don't provoke her as her temper isn't as good as mine. Also, don't say that she's gloomy behind her back, or else I can't guarantee what'll happen next.

The Northern Queen told me once that my parents died because of the Eclipsites. My reason and my sense of responsibility told me that I should use the Northland Mirror, a relic of an ancient civilization, to guard the peace of the Northland. I cannot escape from this past, even though I have no memories of my parents nor know how I feel about them.
I even returned to the house where we used to live in at Lake Mirror. Everything should have been familiar to me, but it still felt foreign to me. I tried to piece together the fragments of my memory, but to no avail.
This space should belong to me, yet I don't feel any sense of belonging.
Only my memories of the Northland Mirror feel real and give me a sense of security...

I dreamed of my sister, Nepolis, when I slept in that frozen cave. She walked out of the Northland Mirror covered with lilies and stroked my face, telling me that the moment was approaching and that it was time to wake up. To wait for the arrival of eternity, I have guarded this frozen city with the Northland Mirror.
I have had the miraculous ability to control the Northland Mirror since the moment I woke up in the cave. Only I know that it is my pledge with the mirror that has made it possible for me to connect with my older sister in the mirror...
I guess that's fine too. My sister and I will continue to guard this frozen continent until that moment arrives.
