Towmuk (Towish Yentenner: Myuuk nun emr Thaok, literally "Toad Log") is a city north of Yentenne, with a population of 400,000. It is composed of marshy swampland, wooden hovels, logs, bridges, and metal shantytowns. It lies over a diamond mine which Sayerthenners force the Towish to mine. Diamonds mined there are called frog diamonds.
