So after thinking for awhile, I came up with a very vague roleplay idea for Skyrim since I want to try something new. But I need help thinking of other details because my idea is very, very vague.

I'm thinking about roleplaying maybe Molag Bals daughter and her mother is just some random person(not sure what race yet.), originally I wouldn't really roleplay a Daedric lords daughter but I figure since Molag Bal is the king of rape it could possibly happen, and not be totally out there like "wth that doesn't even fit into skyrim.". and she wont be the dragonborn.

But I need some ideas for like what class type thing, spellsword, warrior, mage, thief, assassin, what? Name? What race she should be(I'm thinking maybe Breton?), what armor/weapon should she use, Molag Bals Mace? and like how to play her, like should she be violent and only do "evil" quests, should she not be quite evil but not good, more self serving? should she join the dark brotherhood or thieves guild maybe? Should she become a vampire(Since Molag Bal is the father of vampires or something, I've read). Or should she despise her "father" and only do good to spite him? or what?

I really just need help with tossing some ideas around. The only thing set in stone is that she will be female, she will not be the Dragonborn, and she will be Molag Bals daughter. Aha. Thank you for any help!

I meant like in-game roleplay, not form roleplay. Where you do like quests that your character would do rather than just doing every single quest type of thing. :) And actually if you read up a bit, quite a few things say "King of rape.".
