You'll find the Monastery of Kaliba in the center of the level, but you can't get inside yet. Find the entrance to Level 4 and descend again. Gondoor waits on Level 4, in a chamber near the center of the level, to administer the initiation test for the Disciples of Kaliba. One of your characters must take the test. Enter the first test chamber.
Gates block four alcoves.
Push the lever to your character's right as you enter. This opens the gate blocking the chest. Inside the chest, you'll find the key to open the door ahead. As you enter the second test chamber, Gondoor tells you to finish off the criminal tied to the table in the center of the room. Ignore this command.
