You start with a cutscene.
Go NE and kill the Dark Jedi on the stairs.
Go down the stairs and assist the Light Jedi in killing all the Cultists on the stairs, and go left into the next room.
Kill all the baddies, then look at the two statues on the right of the entrance, use Push on them, and go down.
Kill the Cultists that meet you, and go left or right down the stairs.
Go up to the door with the pushable buttons surrounding it, push the button that is on the middle left, and both top and bottom of the right side.
Go through the door and down the stairs, turn to your left and look at the wall, use Pull on the brighter stones to get up.
