The Rings of Pandora are the several circular hallways that surround the lower levels of Pandora's Temple. The first ring is just a long circular corridor, with a passage that leads to the Temple of the Crystal Eye, by pulling the lever the rings can rotate to reveal other passages that lead to the Challenge of Atlas and the Chamber of the Gods which requires both Muse Keys to open the chamber. The second circle is another hallway, with a giant spiked roller running through it. The central ring is a pool of water that surrounds a giant statue of Zeus, within the water there's a tunnel that leads to the Challenge of Hades. Also there's a wooden ladder that can be found there that goes up to a platform which contains a hallway that leads to the Challenge of Poseidon, which the only way to reach it is by jumping on the spiked roller and then jumping on the ladder. As Kratos continues completing the various temple challenges, he goes deeper and deeper into the rings, until he final gains access to the inner most ring, drains the water, and aligns all the rings so that a beam can shoot straight through them all from the Temple of the Crystal Eye, granting him passage to the upper levels of the temple.
