Palace of Twilight

The Palace of Twilight is the 8th and second to last dungeon in The Legend of Zelda: Twilight Princess. Found within the Twilight Realm, it was originally the home of the Royal Family of the Twilight Realm (including Princess Midna) until Zant usurped the throne from Midna and took control of the Twilight Realm. The palace is accessed once all of the Twilight Mirror shards are reunited. This location contains the two Sols, which are later infused into the Master Sword.

The palace contains a new element exclusive to the palace only: Dark fog, a haze comprised of shadow crystals created by Zant. They 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 transform 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 he has the Light Sword.

Obtaining the Light Sword will require Link to return two special objects called Sols 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. Zant's Hand is one new foe that only appears in this dungeon gigantic, indestructible and slow moving hands will chase after the Sol and attempt to steal it.

After a long way to the Dungeon's last floor, the throne floor, Link will reach the throne room and battle none other than the Usurper King Zant.

It is presumed that following her return to the Twilight Realm, Midna regained control of the Palace and lived out her remaining years there as the ruler of the Twilight Realm.
