The Legend of Zelda: Twilight Princess/Palace of Twilight

The first sol
As you arrive, you will notice many twili warriors. However, Minda will comment that they are her people being transformed by Zant. You will come to a fork in the path. Go right. Inside, destroy all the mutated plants and bats. There are statues of Zant's head that appear, shoot a fireball, then disappear. To destroy them, send the fireball back at them with your shield and then hit them. When all enemies are gone, a chest with a key will appear. Get the key, then clawshot one of the targets to get to the ledge and open the door.

In the next room, you will encounter a fog of twilight so powerful that just touching it will turn you into a wolf. While in the fog, engage your senses to seek and destroy the Zant head statues. When they are gone a key will appear. Transform into a human and get the key. Clawshot up and open the door. Jump down from the ledge and a spectral Zant will appear. He will create a red portal and enemies a plenty will come through. Kill the bats that first come out and then find Zant. Do not lock onto him until he starts to form another red portal. Then lock on and hit him. Repeat the process until he runs and causes a fog to engulf part of the room. Run to the other side of the room. You will see a glowing orb.

Minda will tell you that it is a sol and it is like a sun to the twili. Slash at the hand that has it and pick it up. The hand, known as Zant's Hand, will then come to life and attempt to reclaim the sol. Carry the sol to the middle of the room and place in the small hole to make a staircase appear. Go up the stairs and clawshot the sol to make the stair case go down. If the hand got it first, use the clawshot to snatch it back. Go through the door. Zant's hand will follow. Get rid of the rats, then place the sol in the hole in the middle of the room. Climb the stairs that appear until you are on a raised platform, then clawshot the sol. Throw it up a few ledges, then climb up, pick it up, and drop down to the door. Go through the door.

Zant's hand will follow, but dont worry. Use the sol to burn away the curtains of twilight to obtain rupees. Behind one of them is a series of clawshot targets leading to a heart container piece. When you are done, go through the door. Back outside, use the sol to transform all the twili back to their original form. Then place the sol in one of the two holes in the center of the area. This will create a platform to the left, opening the path to the second sol.
