Stay awhile dialogue differences:
Non-Loyalist
"I have made many foes on the path that brought me here. Most of them once called me an ally.
I do not regret the choices I made, nor do I bear ill will toward those who met me with their fangs bared.
But know this: I cannot stop now. I MUST NOT stop now, or all I have done will have been for naught.
Return to Azeroth. Fight the battles ahead of you. One day, our paths will cross again."
Loyalist
"It has been many years since you chose to follow me, despite where I led you.
Know this. I do not deal in regrets. For all that has happened, and all we have done... It would be a greater crime still, to falter now.
Return to Azeroth, my champion. You will be of more use there, in the days to come. And should any of our allies ask...
Tell them that the Dark Lady watches, even now."
Upon Completion you get:
Non-loyalist
"Needless to say, you and I have not always seen eye to eye. All the same, I owe you thanks. Arator is a naive fool, but he is family."
"Now go. See to it that he returns home safely. "
Loyalist
"I am not certain what it says about you, that you have remained loyal to me even now. But I am grateful, for all that you have done. For better or worse, I would not be where I am now without your assistance and counsel."
"Given your position in the world, it would be unwise for me to say such things while others linger. But know this: I am grateful that you chose to stand with me."
