Publishers and the Adherance to Phantasmic Posulations

So there's this story that I've been working on lately. I've written tons of snippets, side stories, and notes for it. I've spent time obsessing, researching, and perfecting. You'd think that, with all the work I've put into it, I might get some money from it some day. Wrong.
My work does not completely belong to me. Why? Because the universe in which it's set belongs to Gene Roddenberry and CBS. That's right, it's a Star Trek fanfiction!
However, unlike most fanfiction, this one is going to be huge. About the size of an actual book. And the crazy part? All of the characters are original.
At this point, you're probably shouting at your screen in frustration at my stupid choices. Why would I relinquish almost all of my creative rights and write about a universe that already exists when I could just as easily create my own?
Because it's a challenge.
I'm being forced to write within the bounds of a pre-written universe. This means that I have to adhere to the laws of nature and heavily research everything. It means that, even though all the characters are original and I'm creating an entirely new species and planet, I have to do things like look up the appropriate uniform for their era, observe proper Starfleet conduct, and make sure that I know the starship's floor plan.
A lot of work is going into this and a lot of work will continue to go into this, and I'm probably never going to get paid (unless they want to buy the story off me). I know this, and I'm fine with it. Sure, it would be nice to see some cash flow from a published book, but that's not really the point of writing. Honestly, I'd be happy if just one person read it. As long as a single person finds themselves enjoying the story, if it opens them to new ideas or viewpoints, even just a little, then my work has paid off.
Plus, if it ends up being a hit, pieces of it may just worm its way into Canon! Did you know that Uhura's first name was created by William Rotsler, an avid Star Trek fan who wrote Star Trek II Biographies, a licensed Star Trek novel (basically a glorified fanfic)? Gene Rodenberry and Nichelle Nichols liked the name, so it was adopted as canon. However, Nyota Uhura's name was never mentioned in the Star Trek movies or show until the 2009 film, taking place in the Alternate Reality.
<takes breaths/>
Whew! Did not mean to geek out so much there. What was I saying?

Oh yeah!
So I'm making this super cool, super long Star Trek fanfic that will probably never make me any money, but I'm totally fine with that and I hope that you guys will read it someday.
Phew.

Logging out. Live long and prosper.
