My current character is pretty much neutral, just as a result of roleplaying. She just pretty much dislikes everyone, and suffers no fools. If people are respectful, she'll respond, otherwise they can go hang. So, she liked the Ithorians and hated the corporate scumbags, but can't stand Vrook.
She's ended up pretty much neutral in alignment, but is usually solving the quests in the LS manner. It's odd.
Also, Visas appeared quite early, I think you get her one you have acquired a certain number of alignment points, whatever side they are for.
