Unicorns, really?

I’ve joined an online writing group called Saucy Ink. We got together at the start of NaNoWriMo, and have stayed together ever since.
Recently, the very talented and helpful Tami Moore came up with the idea of doing a short story compilation. As Tami laid out, there are some solid benefits:
> Practice writing.
> Practice writing on a deadline.
> Practice critiquing each other and modifying our work based on critique.
> Practice editing for "omg, other people will see this".
> Get our names out there. Start DOING instead of just HOPING.
I love that last one. My friend, Mandy, who is biking across the country to raise money for clean water in Africa has given me a case of DOING envy.
We discussed length. 2-7.5k was the U.S. "official" short story length, but we decided to let it go up to 10k.
Then we came to theme. The idea was thrown out of Unicorns. I honestly think it was just a ‘for instance’, but several of group latched onto it.
When I first read the idea of Unicorns, I was thinking how in the world am I going to pull that off, but I actually think the idea might be a good one. It will help me apply some of the techniques I'm learning from How to Think Sideways, and it will give me a chance to do some research on Unicorns. I may come at the theme from a different angle, but I'll see what the mind comes up with.
Actually I do write some fantasy. My last short story was a piece of Blizzard Fan Fiction "The Ashenvale Encounter." I know it sounds crazy, but I'd love to get the rights back to that. It has two characters I really came to like. When you submit a Fan Fiction story to Blizzard’s contests, they get the rights to the story, even if they don’t use it.
My current Work In Progress I consider more general fiction, but the story has a Christian setting and a Christian main character so I can see where people might classify it as 'Christian Fiction'. I love reading fantasy (CS Lewis, Richard Knaack, Margaret Weis, Tracy Hickman, Ted Dekker).
We are blessed to have a profession editor, Steve Hall, as part of our group. We have decided that any profits will go to Steve to reimburse him for the editing work he has volunteered to do on the compilation. We are also retaining the rights to our individual story so I can use it later if I want.
Now to see what twisted tale my brain can come up with.
