I can type some stuff up, and if you need any kind of pictures, I'm pretty decent at drawing too.
You need to include backstory on what started the war, and where the war is now. There are some questions you need to answer like: What started the war? Who are we fighting against? Do Pokemon still exist in society today, or are they kept secret? What regions are most heavily affected? What happened to the gym leaders, elite four, ect.?
