The Lonely Mountain and the Goddess III (Pthora, Cahyali)

The party enters the "mountain," which is clearly now not a mountain at all but a giant building made of black stone and smooth edges. They go inside, and find an atrium with a giant humanoid statue in the middle. Around the base reads a warning, written in some impossible-to-read script as well as Breziak. They solve a few puzzles and enter further, ascending with Mishra's guidance. Soon enough, they find a room with a huge rootless flower which is dripping the black liquid. They cross this room and enter into a grand library, with books and scrolls written in many languages.
