Sorry that I didn't seem to make this clear enough. When I edited the page i thought the chapter initials for the "route" would be concise and understandable.

VA = Vega and Altair Route PR =  Promised Rinascimento Route MWC = Milkyway Crossing Route

They are the chapters from which the worldline is referenced.
