Basic D&D type premise storyline (If I have to do with a setting, I'd go with generic D&D 4E setting and work from there).
Simply put, a Drow escapes from the Underdark to the surface world for their own personal reasons, gets hurt along the way, then ends up in the woods from the cave (or I should say newly made cave) entrance, finds her way to a cabin and passes out (from injury and exhaustion) in front of it. Said person who owns the cabin, lives alone, doesn't have a hatred for Drow (or perhaps no idea what they are), nurses her back to help and we go on from there.
A bit of a forbidden romance, friendship or what have you, depending on how the game progresses. Sex will or will not be present, it really depends on how the characters develop. I want a more "realistic" when it comes to that aspect of the game, not the "Hi I'm so and so, wanna screw?" type story.
The gender of the "lone cabin dweller" can be either male or female. I do not mind whatsoever.
On and Offs are a cheat sheet for sex, seeing as I don't have one, we'll go from there. As it's been stated that I do not want this to be a straight up sex game, just want that has possibility for it. :)
