Slay Anok'suten and return to Arcanist Vandril at Tranquillien in the Ghostlands.
Come closer, I am ... dying.
I was sent here ... to slay these nerubians, but Vandril didn't ... know that they have a leader.
<The dying blood elf coughs up a good amount of blood.>
You must find and ... slay Anok'suten. Get help. She wanders around ... Suncrown Village.
