"Title: Saint Kemmilek Frees the Slaves of Worzog"

"During the Yenid Unification wars, his most holy founder, Saint Kemmilek snuck into the city during a storm, using the clinker-built boats of the River Tribe that can withstand hurricanes, and went to encampments, freeing slaves from their bindings. In exchange for this, many slaves volunteered to fight alongside the Yenids to free the city from the clutches of the ruling aristocratic priestdom."
