The Constantinople Trade Network goes everywhere that humanity has gone.  We puny Earthlings at least.  They’ve even set up some offices in alien space.  Yeah, I’ve been to some of them too.  I’ve really gotten around since The War.  Actually been a lot of places they ain’t seen yet but those are other stories.  And it’s always nice to know that we can come back to at least a small slice of home whenever we find one of their stations.  Real nice.
