Chapter Six: Hell of a Summer

During the Founder's Day festival, the vibrant streets of Waterdeep hide a dark secret within the prestigious Cassalanter Villa. The party must infiltrate the noble estate, navigating through luxurious ballrooms, heavily guarded gates, and suspicious guest houses. What begins as a high-society heist quickly unravels into a terrifying descent into darkness.

Beneath the polished marble floors and manicured butterfly gardens lies a sinister truth. The Cassalanter family harbors a demonic secret, hiding a chained devil in their attic and maintaining a vast, subterranean temple dedicated to Asmodeus. The heroes must race against time to uncover the cult's ceremonial hall, braving fake vaults and family crypts, to stop a horrific sacrifice before midnight.
