Lanfear is an archetypical descendent of Artemis (especially building on Selene). The role of Artemis was highly influenced by male passions. Hunting, sexy virgins, etc. The fact that she will likely decide to hunt you down and kill you just makes it all the more exciting.

Ehh...I'd say Polgara's uber-beautiful and uber-powerful because 1) she's the disciple of a god and the daughter of a sorcerer and a sorceress. The three combine to give her power and lots of it. 2) She went through a whole period of 'My sister is prettier then I am so what's the point in even trying to be pretty?' in her teens. Then she went from one extreme to the other. Also as a teen. As she got older, she got more beautiful (she is a sorceress. If she doesn't want to get wrinkles and become crone-like, she doesn't have to).

Anyways, Pol's far from perfect. She's got a full vocab of swear words, she's stolen, she's dug up dead bodies, she's been a Nyssian dancer/slave/whatever you want to call it, she's turned people into snakes...I could go on and on and on and /on/. But I won't, since I need sleep.
