I'm in search of information concerning the relations between Navigators and Astropaths.
In the midst of character creation for my newly established playgroup, two players quickly expressed interest in being twins. I decided to allow this provided they agreed on a homeworld and created the appropriate backstory. However, when choosing career paths, one became a Navigator and the other an Astropath Trancendent (neither of which were duplicates paths of the other players).
I've been approached by one of the two questioning the validity of their class choices while being twins. After some searching, I was unable to find anything about the relations between the two paths. I'd really appreciate the help of the community in finding (or improvising) some information.
