Quest Mystery of the Pyramid

You are a group of scientists from the Institute of Archeology. Your professor went on a secret expedition. For a long time there was no news from him, and suddenly you receive a letter asking you to urgently come and the exact coordinates of his location. Upon arrival, you find the professor's tent, set close to an inconspicuous dilapidated pyramid. But the tent seems empty, and the professor's things are carried around the outskirts by a sandstorm. Your task is to follow in the footsteps of the mentor, to understand what discovery the professor managed to make, and most importantly, to get out safe and sound. Good luck!
