Ok. I need help. This is my first submisson so go easy on me. I am at the..

Wow, you got to the City in the Sky without help. I'm impressed, and I applaud you. OK, go to where you got the big key. *Drop down the hole in the floor to reach the third level. Open the chest, then grapple the mesh on the ceiling and descend, but don't let go. While you're hanging, grapple to the bronze ceiling ornament, then equip the Iron Boots to start the fan. Drop to the floor and enter the north door. Thanks to the wind created by the giant fan, the large panels will be spinning around. Target their mesh sides and grapple across the gap from panel to panel. At the end, grapple the mesh in front of the fan to reach a treasure chest, then drop, and enter the door. When you enter the far north tower, you'll have to fight two of the small dragon creatures you encountered earlier. After they're defeated, grapple up to the grating on the wall, then to the mesh-covered panel. Use the Clawshot to hit the crystal and start the panels turning. Grapple from panel to panel to climb the tower. Near the top, you'll have to hit another crystal switch to get the last panel rotating. Once it's spinning, grapple to the target above the door then drop to the ledge and enter the boss's lair.

*From this point on my answer has been provided word for word by The Legend of Zelda: Twilight Princess's Official Guide from Nintendo Power.

You can do it.

Thanks for the help joslifer1. I didn't do this on my own. I had some help from a few freinds and a walkthrough but thanks any ways

Remember the part where the giant wind fan is? Shut it off if you haven't. There's a pull switch clawshot it and then iron boots. Next drop through the hole where the big key was. Clawshot the wires at the top and lower yourself. Finally clawshot the last pull switch (to the north of yourself) and iron boots it.
