I'm going to try and keep Author's notes to a minimum after this so please hang in there!

Here's something all of you SAO Fans should know by now - though I did make alterations!

I'm including it so that everyone gets the feels for what Sword Art Online is. If you're a fan then feel free to skip over this without further notice! However, if you aren't a fan -though IDK why you'd be reading this if you WEREN'T a fan (Is there something wrong with you? O_O)- then please feel free to read!

It's the opening of Reki Kawahara's light novel Sword Art Online: Aincrad (volume #1)!

Having said that I DO NOT own Sword Art Online, only various characters within this story (though most of them are Cannons there might be glimpses of known characters so keep that in mind as well).

I, also, plan to make a few alterations format wise (Ex. I will not be including the "« »" when listing things and instead will use italics.)

Rated PG-13 for now, if harder language is used I will be changing it to R.

Thanks for picking my Fanfiction to read, hope you enjoy!

A huge castle made of stone and steel floating in an endless sky. That was all this world was.

It took a various group of craftsmen one month to survey the place; the diameter of the base floor was about 10 kilometers — large enough to fit the entirety of Setagaya-ku within. Above, there were 100 floors stacking straight upwards; its sheer size was unbelievable. It was impossible to even guess how much data it consisted of.

Inside, there were a couple of large cities along with countless small scale towns and villages, forests and plains, and even lakes. Only one stairway linked each floor to another, and the stairways existed in dungeons where large numbers of monsters roamed; so discovering and getting through was no easy matter.

However, once someone made a breakthrough and arrived at a city of the upper floor, the Teleport Gates there and of every cities in the lower floors would be connected making it possible for anyone to move freely through these levels.

The name of the castle was Aincrad, a world of battles with swords that continued floating and had approximately ten thousand people trapped within. Otherwise known as...

Sword Art Online.
