Look at the blue jar

You walk over to the blue jar and examine it. This jar is decorated with images of architectural designs – pyramids, temples and cities, all of which were presumably designed and built by Imhotep. This isn't surprising, since he is known primarily as an architect. You see one pyramid that looks like the one you are in at the moment; beneath it is etched the plan for the interior of the pyramid. You see the shaft you fell into, however, below it, you can only see the interconnected rooms you are in at the moment. It looks like you need to finish your quest in order to escape.

Cautiously, you take off the lid of the jar. To your surprise, when you tip it to the side, there aren't any desiccated organs; rather, two small objects fall out. You examine the objects more closely and see that they are perfect spheres – one made from obsidian, the other from silver. You've been in this pyramid for long enough to know that one of these spheres will be your way out; the other will probably lead you to more danger. You see that each one has a painting of a fingerprint, which you will need to press.
