And how exactly is this supposed to stop the Alliance? Besides, Perenolde's nephew was last seen with Genn in Gilneas. If he is still alive and with the Greymane family, the Alliance will have this "legitimate claim".
For Turalyon? Yes. Even in Shadows Rising he is still portrayed as a good guy. He won't attack first unless provoked.
I agree. Something is definitely brewing with the Sunwell. It would be strange not to use a source of pure Light in a expansion about Light vs Void.
