Firstly, When I say Story Origins, I do not mean the game's story itself, but the characters which you play.
Players should have the choice: Do they help the spiral order, Or do the oppose it?
Are they a knight, a stranger, or a gremlin?
And of the Morai? We don't know.
The reason this is under suggestion is because I'd like to see the other half of the story.
The whole point of the game is that the Spiral Order is trying to get back home. Hell the game is called Spiral Knights. For you to be able to play as anything besides a spiral knight would not make sense.
But yea, we do need to know a bit more about our home world.
