Clarissa, if you're looking for a concept that doesn't step on anyone else's shtick and still lets you indulge in such fetishes as you prefer, you might consider the ship's astropath. There's the whole blindness thing, yes, but you have vast psychic senses to compensate. You could always go with something like that you've kept your other senses (and they've heightened some from compensating for blindness), and between those and your new ones, you've come to enjoy the tactile and sensual pleasures far too much to be seen as proper. Eventually you've ended up on a Rogue Trader to serve there and stay ahead of the consequences of sinking further into degeneracy and desires to explore said senses.<br/><br/>Just a suggestion as people brainstorm.
