Dragon Age Origins Questions?

Ok well I have a few questions pertaining to this game, because its really quite frustrating.



1. If your a female elf can you become queen and rule with Alistair?



2. How can you stay with Alistair if your an elf?



3. Can any of your characters deal the last blow to the Archdemon?



4. If you let Alistair kill Loghain what happens?



Well that's all I can think of for now, so if you can answer any of these that would be great. *I don鈥檛 mind spoilers*Dragon Age Origins Questions?
1. No. Only the human noble can be the queen.



2. Either don't make him the king, or "harden" his personality and he will keep you as his mistress.



3. Only a warden can deal the final blow, that character will die unless you partake in Morrigan's ritual.



4. Nothing special happens, you are asked to choose the new ruler and the game continues. The same thing happens if you kill Loghain yourself. But, Loghain must die if you want Alistair to stay with your party. He will leave you right then if you let him live.
