Expand the Deep Dark lore with new discs and discoveries

The Deep Dark and Ancient Cities have one of the most mysterious stories in Minecraft, but many questions remain unanswered. I suggest adding more lore features, such as new music discs that reveal parts of what happened in the Ancient Cities. The discs could contain sounds of the ancient civilization, the spread of sculk, experiments, and the first encounters with the Warden. Other ideas: - hidden rooms in Ancient Cities with more clues; - new sculk-related blocks and plants; - more structures connected to the Warden; - special events or discoveries that reward exploration. The goal is not to explain everything, but to give players more mysteries to investigate and theories to create.
