Al-Bahamut (Qabiha)

Start at the main entrance of the Palace of the Green Dome on the southwest side of the outer wall.

Turn left (north) from the rebel fighters and follow the wall until you find a crack.

Slide through the crack, turn right, and head southeast towards the gates, assassinating guards along the way.

Break the wooden beam on the gates using a melee weapon or throwing knives to open them.

Once the gates are open, either sneak past the attacking rebels or help them eliminate the guards in the courtyard.

Make your way to the northeast side of the inner palace walls and enter the building housing the Caliph’s harem.

Deal with the guards in the harem, either by using a smoke bomb and assassinating them or by using a nearby musician for distraction.

Speak with the marked eunuch inside the harem.

Follow the eunuch through the opened door into the central part of the palace.

Eliminate the guards in the central area or let the rebels in through the main doors.

Obtain the Caliphal Palace Baths Key from a guard, identified using Eagle Vision.

Go up the steps on the northern side of the dome to the higher levels.

Use the key to open the locked door leading to the baths.

Enter Qabiha’s office, loot the area, and pick up the book from the stool on the eastern side.

Head up the stairs to the right of the stool to find four pedestals.

Interact with the pedestals to recite Arib’s poem and place the blue, yellow, black, and white books on the pedestals opposite their corresponding symbols: Wave (blue), Sand (yellow), Cobra (black), and Dove (white).

After placing the books correctly, a cutscene will play, and you will descend into the hidden chamber.

Walk through the door to trigger a cutscene where Qabiha appears.

Basim will confront Qabiha, but Roshan will kill her.
