The city of Usaro (population 8,790) is the domain of the Gorilla King. The King and his followers are intelligent, bloodthirsty apes who serve Angazhan, Demon Lord of Beasts. Usaro is a monolithic city on the southern edge of Lake Ocota, and its inhabitants are feared throughout the Mwangi Expanse. The King's treasure vaults contain priceless riches, but the ominous sound of human-skin drums carrying across the lake deters all but the bravest or most foolhardy of treasure hunters. In 4706 AR followers of the Silverback King beheaded seventeen missionaries and Aspis Consortium merchants.
