Secrets

 * 2) Look towards the marble steps that lead up to the red bars, then go around the north column. Notice that the north side has a blue light instead of a red light, unlike the other sides. When you press on this light, quickly run to the south side of the marble structure and enter the teleporter before it closes to reach a ledge with an energy cell pack and a soul sphere.
