Vaughan has described Saga as the collision of Star Wars with Romeo and Juliet, and the Star Wars half supplies the universe: a galaxy at endless war between two blocs, a species-diverse cast where nobody comments on anyone's anatomy, bounty hunters as a recognised profession, and technology that is filthy and improvised. What Saga does with it is put a nursing infant at the centre and let the war be the thing interrupting a family, rather than the other way round.
