Gaming A couple Drakenguard questions

[GuyYouMetOnline]

From what I've heard about this game, I want to buy it, but I have a couple questions I need answered first about rumors I've heard.

Question One: Is there an insetous(sp?) relationship between [spoiler]Caim and his sister?[/spoiler] If yes, then is [spoiler]his sister the Goddess? And just what is the Goddess, anyways?[/spoiler]

Question Two: Is there a character who [spoiler]is a necrophiliac (has sex with dead people, or something like that),[/spoiler] and if so, who?

I'd appreciate answers to those questions. Oh, and do you reccommend the game? I've heard it's got a lot of fighting, so I'm interested, but I need answers to the above questions before I buy it.
