Speak to Irya Niashka "The city of the dead is not filled with your typical mindless undead. They are alive and can think for themselves. They appear to have their own politics too, as they have exiled some of their own from the city.For what reasons are unknown. The fact that they are alive goes against all natural law." "Travel north towards the city and you will find the exiled. I want you to personally deliver them back to the realm they came from."
