Gahh, I'm watching the trailer in a loop. It drives me crazy, Who are the voices?

The narrator at the begining is not quite Thordan
So, the dragons are comming - sounds inhuman, but probably not a dragon
Followed by someone. Estinien?
We have a girl praising someone, and a man responding.
We have dreamy voiced woman who merges with Lahabrea. Lassbrea?
And of course there at the very end is someone who recruits the warrior of darkness.

Who are these people?
