They have been benign for many years, but now something has stirred them. They have been a thorn in Mok'Nathal's sides for many years. Some strange religion guides them, a religion which has them in a frenzy of activity. They carry some crystals with them now, which they have turned to some dark purpose. Some of their rituals consist on taking the crystals to their spell circles to infuse them.
They have enslaved a group of ogres in the caverns known as Trogma's Claim and their leader, Vekh is in there.
