Attack the Dark Prince. He won't be defending himself and every your hit will make fading out of the image. You will fall down after a while into the lucid abyss and you will wake up on the great platform. You can't die at this stage, and therefore every fall from the height or slipping into the abyss from the shelf ends with immediate reincarnation in the place where you have made an error in. Jump straight ahead to small round platform, and then the front to the next shelf. Stand near the wall to the left and run over it horizontally to the meet with the Dark Prince.
Attack the Dark one with saber. Two blows and the enemy vanishes. Turn around to the right, take off from the brink to the round platform. Take off from it to next and further away to other platform with the Dark Prince. Kill him, then turn to the right and climb the catwalk. Jump right ahead to the next catwalk then lower from it to the platform below. Take off to the shelf in front of you, flying in the air you will be teleported to the completely different location where you move in slow. Take off from the shelf straight ahead to the shelf with the bridge.
You will be teleported to the lucid world back. You are landing close by the Dark Prince. Eliminate him and turn to the left. Take off straight ahead to the platform, go over the catwalk to the next platform. Jump to the shelf with Dark one, kill him having no scruples. Turn around to the right, climb the catwalk and jump to the catwalk. Take off to the shelf in front of you but before you reach it, you will see the mirage showing your ducal form falling onto the large sailboat. After landing on the shelf jump to the front to the round platform, moving over perpendicularly.
Jump to the next, square platform and from it reach the shelf with the Dark Prince. When you kill him, turn to the right, take off to the adjacent platform. Before you will reach it, you will be teleported to the chamber with large, stone columns and arches. You are moving in slow motion, despite that jump straight ahead to the exit. You will be teleported back to the lucid land. You will land on the oblong platform. Walk ahead over it and from its brink jump to the shelf with the Dark Prince. Two blows and enemy is dead.
Turn to the right, jump to the round platform. The next shelf is turning around in front of you changing shapes - it is sometimes rectangular and sometimes square. Wait until it will evolve into the oblong rectangle and jump to it. Move till its end, then take off to the platform with the Dark Prince. Kill him, turn around to the left and jump to the round, moving platform. Wait until it drives you to the right, and then take off to the square shelf with the wall on the right. Run over the wall horizontally, you will land on the shelf with Dark one, kill him. Turn left.
Climb the catwalk, then jump to the next, revolving one. Wait until you will turn around along with the catwalk's end in accordance to the direction of your travel and take off to the next board. Jump to the shelf with your enemy now. You won't reach him because you will be teleported the to the other location. It is substantial chamber with big stairs, where Farah is standing at. Come up to her, hear hers warning. You will face the Dark Prince again after a while.
Unfortunately, you can't defeat him because his look-alike is rising after every blow. Dozens of enemies will surround you soon. Give it up. Pass over the whole crowd and run up the stairs. Enter the lucid gleam and..... you will wake on Farah hands. It turns out that you lose consciousness after the fight against the Vizier and you had delusions. The Dark Prince is no more. This is really end of the adventure. You are true Persian Ruler..
