The first volume is going to be about the human-dragon war. There will be approximately 25 arcs, all differing in size. The war will move us through all five kingdoms, the Dragon Continent regions, and some neighboring islands with different species. The story will definitely not end after this volume. I am thinking about either 3 or 7 volumes. The story after the 3 volumes will be different from the first 3, so I'm thinking of making a sequel containing them, but I'll see when the time comes.
