You are traveling through the underground of Gensokyo, exploring the immense cavern that leads to the Ancient City. For some reason, you notice a huge amount of ores that seem to have special properties. The further you venture, you notice that you have entered a part with remarkable Egyptian architecture

However, your progress is blocked by a woman with long dark blue hair and equally blue eyes. She wears an archaeologist outfit along with leather boots and she has several Egyptian ornaments decorated on her body, including two golden staffs. She has a blue tint under her eyes and wears a golden tiara. She has four key-shaped earrings to symbolize the four entrances of a pyramid

"Stop right there, human! You're not going anywhere until you solve my riddles!"

She speaks in an authoritative tone while smiling smugly. The passage behind you is instantly blocked, as if you can no longer leave or pass until you do what this mysterious person wants
