Dominion Rod
From Zelda Wiki.org
The Dominion Rod is found in the Temple of Time, the sixth dungeon in Twilight Princess, and is used to bring certain statues to life. This causes the statues to mimic Link's movements. If you walk in a certain direction, the statue will move in the same direction. Press the button with the Dominion Rod on it and the statue will perform an attack.
Once leaving the portal that links the Sacred Grove to the Temple of Time, the Dominion Rod will lose its power. After receiving a book containing sky language and giving it to a man named Shad, who has recently discovered an owl statue different from other ones he has seen across Hyrule, he will read the text, only to fail to open the path that leads to the heavens. However, the ancient text he reads is a spell which restores power to Link's Dominion Rod. He must then travel across Hyrule to various Owl Statues, and use the power of the Dominion Rod to move the statues. Under each one contains an ancient character, and Link will need to acquire each one to complete the book.
The Dominion Rod is the key item used to defeat the boss in the Temple of Time, Armogohma, the latest reincarnation of Gohma, a boss who appears in many previous Zelda games.
