Palace of Twilight

The Twilight Palace is the 8th dungeon in Twilight Princess. It is home to Zant the Twilight King and is where the Master Sword is upgraded to the Light Sword. The boss is none other than Zant himself.

The palace contains a new element exclusive to the palace only. Dark fog, a haze comprised of shadow crystals created by Zant, are the pure essence of darkness and shadow, and the element is scattered across various locations of the Palace. If Link enters the fog, he will tranform into his wolf form, and will be unable to turn back into his human shape until he leaves the fog. Link will be able to cut the dark fog once the Master sword is filled with light. thus forming the Light Sword.

Obtaining the Light Sword will require Link to return two special objects to the entrance. The Sol to the twilight realm is like the sun to the light world: it is vital for life and energy. The two Sols are located on the first floor on the west and east sides of the palace. Link will be forced to fight Zant's Phantom twice, once for each Sol. Link will then have to utilize the Sol to activate platforms that lead him back to the dungeon's entrance, while retrieving the Sol before these mysterious hand-like monsters resembling wall masters, given the name Zant's Hand, take the Sol back to its resting place. Returning the two Sols to the entrance will turn the Master Sword into the Light Sword, and allow Link to make his way to Zant's throne.

In addition to regular monsters seen in the twilight realm, Link will also encounter monsters that resemble Zant's mask, thus given the name Zant's Mask, also exclusively found in the Palace of Twilight. They will periodically shoot blasts at Link, then warp to another location. Link will frequently need to defeat these monsters to get keys in the Palace.
