I was just wondering something about Astropaths, soul-binding and the damage done to the eyes.
In Dark Heresy, there was the "Optical Ruptures" sanctioning side-effect, which sounds suspiciously familiar to the damage that Astropaths suffer to their sensory nerves, particularly the eyes. In DH, however, your ruptured eyes are replaced by cybernetic implants. Is this viable for Astropaths as well? Or is it that the nerve itself is irrevocably damaged? I've seen some pictures of Astropaths with perfect sight, some with blind eyes, and some with no eyes whatsoever, so I'm getting confused. Can an Astropath somehow regain his/her sight, and does he/she have to lose it in the first place? Would cybernetic implants suffice?
I'm asking all of this because I would like to think that my adept-turned-psyker, who lost her eyes already to the sanctioning, could transition to an Astropath and still keep her cybernetic implants and do her duty on a Rogue Trader ship. If not, at least can she keep the implants for cosmetic reasons? I really don't like the empty socket thing, even if it's a "mark of honour" for some.
Also, can Astropaths read? Books? I know they can perceive things with their heightened senses, but reading is a bit different than perceiving.
