The Dagger of Time is an Artifact linked to the Sands of Time. It enables the wielder to reverse, stop, slow, and use various Sand Powers, as well as protect him/her from changes in the timeline or alteration by the Sands.
Pre-Game
The exact origin of The Dagger of Time is unknown; however, since the Sands of Time were created on the Island of Time, it's likely the dagger was too, though for unknown reasons. It was later stolen from the Island of Time by theMaharajah and his Vizier along with the Sands. The Dagger was placed in a glass case in the Mahajarah's treasury.
Sands of Tim
The Maharajah's Vizier betrayed him to the Persians to get at the Dagger to open the Hourglass. However, the Prince got to it first during the siege, so the Vizier could do nothing, as Sharaman refused to take away his son's well-earned prize. But as the Persians presented the Sands to the Sultan of Azad, the Vizier manipulated thePrince into releasing the Sands, claiming that there lay a marvel within.
When the Sands are released, the Dagger prevents the Prince from being mutated by them. After returning the Sands to the Hourglass, he reversed time to the point before his army attacked India. He gave the dagger back to the Maharajah's daughter, Princess Farah, telling her to lock it back in the Maharajah's treasure vaults.
Warrior Within
The dagger's fate is unknown. Presumably, in the present it is still secure in India, while in the past it is locked away somewhere on the Island for the Maharajah to find, or had not been created yet. Whatever the case it plays no role in the game.
The Two Thrones
Due to the Prince's efforts on the Island of Time, the Vizier is still alive. Motivated by dreams he had from the dagger of the Empress's return (presumably when she entered the timestream in the present day), the Vizier kills the Maharajah and steals the dagger for his own. After conquering Babylon, he then killed Kaileena with the dagger, recreating the Sands of Time and absorbs them into the dagger (though not before they transform his generals and, partially, the Prince himself). Through its power, the Vizier became Zurvan, a youthful, immortal, though monstrous, being.
The Prince takes the Dagger of Time after the Vizier stabs himself with it and becomes Zurvan. With it the protagonist can use the following time powers: Recall, Eye of the Storm, Winds of the Sands and Sand Storm, all of which help the Prince in his journey to defeat the evil Vizier. The Dagger of Time is taken away by Kaileena's spirit when the Prince kills Zurvan.
The Prince was able to grab the Dagger before the Sands could fully mutate him, though it couldn't stop the emergence of his dark alter-ego, the Dark Prince. At the end of the game the Prince uses it to stab Zurvan (apparently it was the one thing that could undo his immortality) and then returns the dagger back to the spirit of Kaileena and it is removed from the world to prevent anyone else from using its powers.
Sword of the Mighty Warrior
The Sword of the Mighty Warrior is the seco
It is found upon a pedestal that sits above the baths of the Palace ofAzad, and it allows the Prince to break cracked walls in three hits. You can also see this sword on the ship in Warrior Within; its user is the crew member who charged Shahdee.
Sword of the Avenging Warrior
The Sword of the Avenging Warrior is the third sword the Prince gets in The Sands of Time.
It is found it in Azad's Halls of Learning, and it allows the Prince to destroy damaged walls in a single hit.
Sword of the Enlightened Warrior
The Sword of the Enlightened Warrior (also known as the Damascus Sword) is the fourth and final sword thePrince gets in The Sands of Time.
After Farah seduces the Prince and steals the Dagger of Time and the Sword of the Avenging Warrior, he then finds this extremely powerful sword. The Prince finds it after waking up and finding Farah gone. It is on a pedestal and is guarded by a glowing aura that will harm the Prince if he touches it. The Prince will also pass several sand monsters which, luckily for him, ignore him until he arms himself with the blade. By solving a light and mirror puzzle the aura is lifted and the Prince can obtain the weapon.
This sword is a deadly weapon that will flat-out destroy any sand creature it touches, killing them even without the Dagger of Time (although for gameplay reasons this is because the Dagger is not in the Prince's possession while he wields the Sword of the Enlightened Warrior). The cost of such power is that for the brief time the Prince holds both the Sword and the Dagger, he cannot retrieve any sand unless a sand creature knocks down its ally.
The Sword of the Enlightened Warrior is lost when the Prince performs the Grand Rewind, unlike the Dagger of Time, which could be because he never had the sword before the events of the game, or it could because it is not a artifact made by the Empress of Time.
