Gravity throne

Gravity Throne

Gravity Thrones are the main form of transportation for the higher Prophets of the Covenant.

Summary
Instead of walking, Prophets choose to sit on these levitating thrones most of the time, which would make their lives more comfortable, due to their frail bodies. The High Prophets have a version which is equipped with a shield that is impervious to nearly all small arms fire.

It is also equipped with a modified version of the Hunter's Assault Cannon. This weapon is called the Gravity Cannon. It appears that each throne has a holographic projector, the Hierarchs' including a series of small holographic buttons that can perform a variety of commands located on each armrest.

Lesser Prophets do not appear to use these thrones as often, but Prophets serving military roles (such as the Legate) have Gravity Thrones of their own, though the version they use is less advanced (it seems they don't possess weaponry or shielding). Other, usually lesser, Prophets also use Antigrav Belts.

Fleet Master Elites use a lesser but similar Gravity Throne without weaponry as seen in Halo 3. Ship Master Rtas 'Vadum sits in one and gives it to the Arbiter at the end of the game. However, it probably is just the ship's commanding seat.

Lesser prophets can utilize similar anti-gravity chairs. They can travel closely together in groups within anti-gravity rings to achieve powered flight. Seemingly, as prophets are granted higher ranks they are given more powerful chairs allowing them to travel in smaller groups. Prophets that are Ministers or above are equipped with gravity thrones that are capable of individual flight. In Halo Wars the Prophet of Regret can be upgraded to use a throne that is capable of powered flight.

In Halo 2, various mods made the Gravity Throne a drivable vehicle.
