On the 1st dialogue of this quest (the one to unlock Neverreap) :
I don't think this comes from any quirks of the Vanu's way of speaking.Quote:
Sanu Vanu: Tonu Vanu will your be guide. He awaits you outside the village. Pray go swiftly, netherling, and chase away the coming storm.
Edit: this also repeats on the small talk by the npc after taking the quest.
