Emboldened with the quest to stop Kalak’s resurrection, the Children sought out the Key, a mystical artifact able to open the lowest chambers of Kalak’s Ziggurat. After a bloody yet victorious battle with their rivals, the Red Bones, the Children traveled to the burial ground of one of Kalak’s most ruthless templars. Routing Kalak’s hired Toothcutter slavers, the Children entered the Templar’s catacombs and defeated his restless spirit before recovering the key.
