Enter to the gate and go a bit further to the right, and then to the left. When you reach the chasm, stand near the left wall. Run over it horizontally and when you are almost falling, bounce off hard to the right. You will land on the rocky shelf. Localize the ladder affixed to the rock and jump on it. Clamber upwards, at its top take off backwards, landing on the rocky ledge.
Arduous climbing upwards awaits you now. It isn't easy - not only it is necessary to jump from the ledge to the ledge (at big height), lethal arrows are still flying out from openings in walls. Luckily as in the channels there are breaks between each series, which you can use to go upwards. From the rocky ledge which you reached from the ladder jump upwards to the higher window-sill. Jump on the opposite window-sill from here and last one jump after which you will catch the brink of the surface of the ground. One more effort you are found on the open air.
Run carefully with the rocky tunnel, watching two Archers, being on guard in the distance. Skip the first precipice and the other, close to the small cascade, oozing from the rock on the left. Kill Archers before they will stuff you with arrows. There is watchtower located high, which you must reach. You can see the narrow rocky ledge in front of your, run to it. Jump upwards and clamber up the shelf above your head. One more jump and you are sticking to the brink of the long slot.
Moving with short jumps, go right to the end of the crack. Lower to the ledge under you. The ground is instable and it will collapse immediately so take off fast backward, to narrow rocky shelf located on the opposite wall. Jump upwards catching brink of the next, oblong rocky crack. Move over with jumps to the right side, lower to the ledge below. The ground is also impermanent, therefore go with lightening speed to the right and jump backward to the platform behind your back.
Go through the platform to the right, jump on the higher shelf. You will reach two wooden window-sills at the foot of the tower from it. Be careful, openings which killing arrows are flying out from are under shelves. Jump on the lower window-sill, clamber to it, then to higher and as soon as possible move on hands for its right end where are no openings with flying arrows.
Clamber up the catwalk, look upwards. You have next two catwalks above the head, at the same time pulling out and hiding to the wall. Sense the moment, when both will begin to pull out and jump with lightening speed on lower one. Jump from it at once on the higher neighbor. Execute the last jump without any moment of the standstill and this is the top level of the defensive tower.
Go to the other side of the tower and peek at the courtyard. You will see the strange scene, during which one of the Guards will stick the sword into the magic pile - Sand Gate. The clear trail will spout upwards from the pile and you will distinguish outline of the lucid form among glitter. This is metamorphed Vizier - remember him well because you will meet him again. The fountain is on the tower, use its kindness power before continuation of the travel.
