Hey writers, whats the longest cohesive story / fanfic that your wrote by yourself?

When I was 10 years old I filled up an entire 70 page, wide-ruled, spiral bound notebook with my book called "The White Stallion". Not sure how many words it was, but it was about one twin being kidnapped by "Dark Phantoms" and the two twins subsequently being transported to another world called Honorah through a dark stairwell. The leader of Honorah was a unicorn called Hango who had the ability to heal people. It was basically a rip-off of Narnia. Some noteworthy excerpts:

EDIT: I'm changing the excerpt because this was just too good to not post:

"I must be drinking too much, she thought. Maybe come alcohol will do me some good.

But right then, a dark shadow came into her room.

Ms. Harrow screamed.

'Okay, okay,' she told herself. 'Maybe I had drunked[?] myself too long. Maybe they're friendly, but I can't remember anything.' She thought for a moment. 'But maybe they aren't friendly!'

Apparently Ms. Harrow didn't know the difference between a Dark Phantom and a Good Spirit, and that the dark shadow was a Good Spirit, and was trying to make peace between her and the twins.

Ms. Harrow had no idea.

'We are Good Spirits,' one of the dark shadows said.

'W-what are you?!' Ms. Harrow questioned.

'Geesh! You have the easiest name, and they still don't understand!'

'I'm sorry,' Ms. Harrow said. 'Hello.'

'We are here to make peace between you and -' she took out two name cards. 'An-gar-ia and Lor-ia-jun.'

'An-jer-uh and Lor-uh-gen,' Ms. Harrow corrected.

'Whatever. We are here to make peace between you and the twins.'

'No way!' Ms. Harrow shouted. 'I am not gonna make peace with them!'

'Peace.' The Good Spirit raised her hand and threw magic dust in the room. 'No evil will enter here.'

Ms. Harrow slapped down her hand."

I actually have no idea. I was always measuring my stories in pages not words. O.O
The longest story I`ve ever written probably is about 100ish pages long. It was about secret agents from the land of light infiltrating in the land of darkness to gather information about their ruler and his family. And then some shizzle happened when they got caught. 😃 But it was going to be a two parter, so idk if I call that a full story. I also have had a few unfinished stories that might have been longer tho, but they vanished into the void when my hdd crashed, so I have no way to find that out now.

I've filled out 10 of those 70 page notebooks. (so literally 700 pages). Actually mustering up the motivation to type the digital copy is the problem.

On top of that I have three seperate books; one to keep track of characters (ages, heights, looks, personalities, origins, and extra info like favorite colors and such). One to keep track of the planets (gov type, flag colors, emblems, maps, customs, real world locations they're based on, etc). And one for timelines alone (one for each character as well as a time line for each planet and its major events and then one giant one for everything together.)

I've been working on this thing and altering it pretty much my entire life.
