The Ironclaw Warband: Cave of Ceremonial Events

An ancient cave dedicated to Kir'ag the orc god of Conquest and deomination, located on the mysterious black isle. Legend claims that the black isle was the place of battle between Gods and Other worldly beasts, and that the black tainted rocks were marked by the bursts of powerful dark magic. The cave was said to be carved out by the Gods themselves after their victory to drink from the fountain of blood. Credit to Tytos_Bane
