The Beginning

A/n: well...welcome back. Let's hope you paid attention...

~~~

???1: oh! Oh! And then what happened?

???2: No! That's too boring! Mx.halia, can you tell us about the story of memories and knights?

???1: Nooo! That's too boring! And morbid!

???2: But it's fun!

Halia, chuckling: children please, I don't mind telling either story...but there are things I have left out from my first telling of it...

???3: really? Like what, mx.Halia?

Halia chuckles and uses magic to grab a book, setting it on their lap and opening it as the five children gather round, trying to look at the pictures. Halia chuckles and covers the room in a very light layer of ice, which now shows images.

Halia: now then children, gather round. It is time for me to tell you the story of memories and knights. Of light and dark. Of love and hate...and of war and love. Listen carefully children, for this is the story of the X-Event and of what happened after...of what happened to everyone...

???4: Mx.Halia, why is the room covered in ice?

Halia, chuckling: well, Laria, it is going to help me tell the story. I find that stories are better told with images and if you can visualize them...but that's a personal preference.

Laria: oh...then start telling it!

???2: Yeah, tell it!

Halia, laughing: alright, alright, calm your feathers Aizza! I will...now Odeyssus and Poppy, I ask that you two do not use your powers, alright? This is a story that I must tell on my own...besides, it'll ruin the surprise!

Aizza, grumbling: ugh, fine!...hey, what's that look for Lilith? It'll be fine!

Lilith:...I still don't we should be listening to this, but I am curious...are all of us supposed to use our powers when you're telling the story?

Halia, chuckling: it would be easier for me to tell the story if you five don't use your powers. It helps me concentrate.

Poppy, rolling their eyes: alright old lady

Odysseus: Poppy! That's rude!

Poppy: am I wrong? They're older than us by centuries!

Odysseus: and they're the ones that took us in, so we should be grateful

Poppy huffs and crosses their arm-wings, pouting. 'Halia' chuckles softly and shakes their head, their wings fluttering.

Halia: settle down, settle down...it is time for me to begin...and to truly understand everything, we must start at the beginning, the very beginning, when Y/n, the guardian of memories, first found the guardian of negativity, Nightmare and his brother Dream, the guardian of positivity...you remember their stories, no?

Kids: we remember Mx.Halia!

Halia, smiling: good...now let us start...it all started on a clear day, no clouds in the sky, the wind blowing gently, and the villagers talking amongst themselves in their village...

~~Y/n's past~~

It was a wonderful day out. Birds were singing, flowers were blooming, and on a lovely day like this, it was quite hot out as a small skeleton clad in purple glanced at the sky, before looking down at his book, seemingly more interested in that than whatever was going out in the surrounding area, but still keeping an eye on his younger brother, a small skeleton clad in blue and yellow.
