Ever had a problem with having a awesome fight/battle scene that you want too write , but you it doesn't fit in the plot of the story your writing? Or you don't want to write a new page about it becuase you don't really want to contiue it? Well this is the place you can put it. write any variety of fight and have as many or little chapters about, If you want to have the chapters connected just mark it clearly in the title somehow. Have fun and go wild.
