Enter the mysterious world of the snake-like yuan-ti... Hlondeth - A city populated by the humanoid serpents known as the yuan-ti, and ruled by House Extaminos... This powerful House of Serpents is the ultimate target of The Pox, a human cult whose members worship the goddess of plague and disease, and who begins to work the deadly will of Sibyl's Chosen, a dangerous cabal of yuan-ti who will turn every human in the city into a freakish tainted one, unless Dediana, a yuan-ti half-blood, can stop them all.
