The dragonborn have an annual festival dedicated to the ancient dragon gods. During the previous festival, the elders called Korinn aside and told her of a prophesy and a gift. Their auguries told of conflict, and in response, the dragon gods bestowed upon Korinn a package. They left the warning that the package was only to be opened in times of great peril.
After defeating the skeleton guardians, the party prepares to enter the ritual chamber. FLoki sneaks into the room, seeing 2 yuanti near the entrace and 2 more yuanti standing near the dais at the far end of the chamber. The yuanti have an undead-like quality. On the dais, Phyla is standing behind an altar holding the snake dagger. Behind Phyla, a large snake abomination is chained and impaled on the wall. As Floki enters, Phyla calls out, "Welcome to the domain of the snake gods! Your sacrifice is accepted."
Two of the yuanti approach. Using an illusory barrel Arlen created, the group slays one of the yuanti. While the party is distracted by the yuanti, Phylla runs toward one of the grates on the ground and slices her hand, pouring in her blood. As the blood seepd into the drain, a mass of writhing snakes swarm forth. As one of the yuanti attempt to ensorcell Korinn, she receives a vision from Bahamut, revealing the contents of her gift from the dragon gods, a tear a Bahamut. Tavon and Arlen team up to kill the yuanti who attempted to charm Korinn.
After the closest yuati were killed, the party advances into the chamber. Phylla pors more blood into the drain, summoning a large snake. Cartumel shoots Phylla, knocking Phylla unconscious. As Phylla falls, she screams "You will be the instruments of his rebirth. Master has me."
