The Nexus Universe is my world building project for 2014. It is a science fiction setting that leans more towards space opera than hard sci fi. My goal is end up with a setting that can feature multiple types of stories from military action, to espionage, to exploration, to Firefly-esque capers. In any case, this is the first, short, article that introduces the reason that species come into contact with one another – space travel and the Nexus System.
