I have to get going soon, but if nobody else gets on today I'll be back to give you a whole rundown.
We had a recent mishap that led to us having to remove our comprehensive class list, but we are pretty fluid. Really, its just the best summary of your class that you can come up with.
Races are a different matter, in that we give no guidelines what-so-ever. We have had vampires, cyborgs, demons, all kinds of stuff. The story resolves heavily around the mysterious creator "Dark Angels" and the ambitious "Grim Angels", whom Lloyd or Phoenix could tell you much more about. However, I am a unique race called a Titan, which we haven't explored yet. You get free roam, we only really ask that everyone do what is best for the story.
When I get a chance to get on for longer I will recreate some of the classes from memory.
