Tales From the Yellow City
Kesht is obsessed with the pursuit of pleasure, and increased magical power. He intends to use his position as a librarian in the Yellow City’s Grand Library as a front for a pleasure den drenched in opium, decadent food, and other carnal delights.
Kesht has an ugly, incompetent, human apprentice named U Du Ban. The slug-man often wishes he had someone more competent and cosmopolitan.
