When you come back
So you've come for training, then?
When you hand it in
You are about to embark upon a dangerous journey. Our world is changing and it will need those who have the will to lead and protect others if our people hope to survive. As you grow in power you will need guidance. Come to me--I will do what I can to train you as you progress.
Good luck, Zaelriel, may the winds guide you.
