Not that I have any vendetta against you Mr. Block. But I think the words "bad blood" stand out here.What is the morality of bringing bad blood and tribes from other worlds to a new world? World Seven is one of the biggest microcosms of this idea I have seen in my TW experience. The wars and sides were chosen before BP ever dropped based on beefs from W1. This puts hundreds of 'Innocents' fighting for a cause that they do not understand or even know about. They are not fighting for themselves but for the causes created in W1. This is akin to imperial powers moving in to Africa and using the local populations in their armies. On the other side of the coin if these tribes are great enough to dominate the first world I would say they have the right to spread to any other world they want and show their skill again.
Im pretty hung over,
