Slay High Priestess Azil and 101 Devout Followers.
The documents detail the arrival of High Priestess Azil to the depths of the Stonecore.
Azil is described as a high-ranking member of the Twilight Council. Additionally, her entourage of over a hundred devout followers is preparing for an unholy ritual of unforeseen darkness.
Sounds like an event you need to put a stop to.
