I am currently a writer in Darkfighter, an RPG where you apply for a character, and if you get them, you write that character's story.
It's a little hard to explain.
You know what? I'll just provide the link.
The Darkfighter RPG
My characters (so far) are Marionette and Shadow. I'm currently trying to get Felicia, my third character.
