Vanity's Brood

Medusanna, a priestess of terrifying power, convinces the Se'sehen, a yuan-ti tribe from the distant jungles of Chult, to serve her growing cult of Sseth, the merciless god of the serpent people who languishes in the foul plane of Smaragh, where a trapped and desperate Karell can only hope Arvin will find her before the House of Serpents finally destroys their last hope for freedom.
