Rape is not good in any game unless it makes you die from trying to or after you do it. Its just morrallly wrong and over steping gaming bounds. And if you would really click that option that says "Rape her" You have a bit of a problem. Sorry just kinda had to add that.

I don't object to rape in an RPG on moral grounds, however, I just find the idea dull.
In my opinion, "evil" is a way of viewing the world and moving through it- not just a label you stick on a character as an excuse to do whatever the hell you want.
Evil leaders inspire loyalty in their followers by inspiring fear and dominating their will. Rape doesn't do either of that- it bypasses one's will completly, and will most likely serve to piss someone off more than fear you, or be loyal to you.
It gives the player no dialog, no psychology, nothing to figure out.
That seems pretty boring to me.

Not to mention the matter of logistics. How do you rape someone who can turn into mist at will?

Rape is used by slavers(amongst others) to break/weaken a subject's will, inspire fear, show dominaince, and instill a worthlessness in the subject. It is often a tool in such cases and little more. I do not believe the PC would have a reason to rape any of his follower as they are all rather loyal. Then theres always inspinct and lust. It wouldn't be fitting to rape someone who has served you so well, a party member for example. A restrained enemy, a random peasant, sure. But those who are using their bodies as shields to defend you, your loyal servants(they might not realise it, but face the truth, that's all they ever where)? What fool would do that? I doubt someone as compitant as the PC would so short sited.
Now a Vampire from the Anne Rice Novels is no doubt differant than a D&D Vampire. Every RP and story has it's own varriation. No doubt any mundane creature would have to either be in love, seduced, or (in my case)have a morbid bent in order to be in any form of relationship with a Vampire that doesn't end is cold glares(at the least). There are many types of "romance" and many views of it's definition. I'm looking forwards to seeing how Thorium developes this relationship, however distant it might be. Personally I am pleased to have another villinious character to add to my group's roster. More content and detail to that character is welcome. From what I've read of your post(which is very little, to be honest) you have some interesting ideas for this expansion. I wonder how they will blend together.
