Elune is with you, <name>. The wind whispers it to me, and I'm glad I can directly take part in the shaping of our next generation of hunters.
From what I have been told, you are close to Aldrassil. I would meet with you inside the great tree when you have time.
Our elders have charged me with ensuring that new hunters are properly trained for the trials ahead. You being one of the newest students, it would behoove you to visit me. Until then, be well.
