- "Illyria was a great power—so great that, after millions of years dead, somewhere on this Earth still has acolytes."
The Acolytes of Illyria were the worshipers of Illyria, one of the Old Ones. Illyria's power and influence was so great that by the 21st century, millions of years after her death and interment in the Deeper Well, she still had followers who coordinated and collaborated in her resurrection plans. One of them was Knox, who became Illyria's Qwa'ha Xahn.
Although there were only two identified members of the organization, it was implied that there were many other active acolytes throughout the world and the dimensions.
