The Knights of Avarrocka were a small group of soldiers sent to slay Enakhra and destroy her temple. However, they failed, being quickly slain. One of their members, Pentyn, was kept alive in order to fuel a spell trapping Akthanakos, being tortured and starved for thousands of years.

^Pentyn, "Enakhra's Lament", RuneScape. "Besides, I am already wounded, and have been so for many years, thanks to this spell you cast on me. And hungry. So very, very hungry."
