I know there will be no continue, but, why do you 'always' make an open end?
I wouldn't call the end of The Fall of a Leader particularly open, either, since both Stormblade and Shadowdart's storylines have been resolved; while we don't know what happens to the swarm, that's something that is to be found out in the future of The Quest for the Legends. The Quest for the Legends' end is very definitive and not open in the least, but of course it will be a while before we get there.
P.S. why, and how, did Stormblade bring nightmare, and HOW did he find her?
…didn't you read the chapter where he found her? o_O I think it's the second chapter in part VII.
