Choose your party and then enter.

Pick up the Aquarius Stellazzio to the right and a Dagger to the left just inside.

Go through the door in back to find Kumool the moogle. Get the Cat's Claws in the top left then slide down the pole.

Climb up the ladder next to the pole, follow the balcony around and hop onto another ladder. Climb up and get off on the left to grab the Javelin, jump off to the right to grab the Broadsword.

Now climb to the bottom of the ladder, jump off, continue to your right and hop onto yet another ladder. Climb up until the screen changes, then jump off and grab the Rod.

Climb to the top and enter the doorway on the small balcony. Examine the fresco on the left and choose the options in this order: Examine, Push, Pound, Think, Push, Try something drastic, Rest. Pick up the Barette on the balcony and then go back and go up the elevator in the rear.

Take all 4 mirrors. When you try to leave, you'll have to fight Taharka.

After defeating it, return the way you came. After you climb back up the pole to where Kumool is, drop through a trapdoor just below the chest at the top to grab a Maiden Prayer.

At the entrance, a new door has opened up next to the first one. Go through it and continue on until you come to a new area. Grab the Air Racket at the far left and then descend the elevator in the center.

Open the chest to get the Golem's Flute, then move the vases counter-clockwise until the power fills the vase. Take the vase to get the Ancient Aroma.

Return to the courtyard once more and climb the pole up to the chandelier, where you'll get the Mage Staff and the Fork.

After you exit the castle, you'll have to go back alone as Zidane to rescue Amarant. Go back in and go down the pole but head towards the left front. When you find him, exit back out of the castle with Amarant.
