I need help, or someone write this for me!

I'm thinking about writing a fanfiction. Unfortunately I'm more used to writing poems, essays, round robins, and game design. In other words I have no clue how to even begin, that plus I'm unsure where to place this makes starting somewhat difficult. Anyways find the details below.

Fallout: The Brony Chronicles

Basic premise:

Pony fandom convention meets new age spiritualism trapped in a vault for 200 years, stir & mix. I justify this by saying fandoms are weird. Some people are crazy devoted to their fandoms, to the point some would consider it a religious devotion. Also with pastafarians an actual thing I can totally see someone going "Pony religion LOL!" (Actually I've thought about it myself I even have an outline for it.). Take that and add trapped in a vault for years, and with nothing to oppose it a single fandom could easily overtake a vault. Think about it with little or no new entertainment what you got would become popular. In fallout on the goat there's even a question about a comic book and obtaining it. The choices are: steal it, kill for it, trade your most valuable possession for it.

Also with the habit of parents sparing their children the harsh truths of the world by either lies, misinformation, or "when you're older". It'd be easy for one parent to answer of "What is radiation?" with "It's like magic, it does strange things to you if you are in it long and can even hurt you. But without we'd die because the reactor runs on it and gives light and water." For kids to think Rad = Magic. From there just a bit of willful ignorance or childlike exuberance for such misinformation to become The information.

Don't forget that the vaults are largely human experiments to develop a better society. They have vaults with FEV, vaults with faulty shielding to see what happens, and so on and so forth. But scientific rigor calls for multiple iterations of the same experiment with new variables introduced. So here's my premise: bronies + religion + magic = this story. Magic is somewhat canon in fallout remember the book of Krivbeknih. Also I justify my use of giving bronies magic via FEV and radiation. After all giant ants exposed to FEV breath fire, humans exposed to radiation mutate and become ghouls. There are even ghouls that glow and pulse out radiation called glowing ones.

The setting would have to be central US, seeing as both west and east coast is taken. A random numbered vault somewhere in the great planes area. For the story the first half of it would focus on the vault. Vaults are essentially self sustained cities that are underground. I was thinking of having domesticated fire ants the size of dogs be part of the vault. After all meat is meat, plus it's nice to justify a game element I want to add. Also it allows me to play with FEV and Rads to justify "magic". From there the reason for the main character to leave the vault is easy. Bring the magic of friendship to the world. You are largely a door to door Mormon possibly with a gun. Also you might be trying to find out what happened to the other missionaries that have gone before you.
