Tiara

The Tiara was a space station in equatorial geosynchronous orbit over Utgard, on the human colony Harvest. Constructed in 2468 when Harvest was founded, it supported the seven space elevators servicing the colonies capital city of Utgard, and functioned as an orbital port for passenger and cargo transport, as well as the storage area for the data centers of the AI Sif, who was in charge of Harvest's shipping operations and maintaining the Tiara 's position. It was not present in 2502, but was fully functional by 2524.

The Tiara is described as two arcs separated by the carbon nano-fiber strands that made up the space elevators of Harvest. The beam work connecting the two looked like delicate filigree. Six beveled titanium spars ran the length of the facility. Avery Johnson estimated the station was about 4 kilometers long and it's interior around 300 meters in diameter (13,200 and 990 feet, respectively). It possessed some form of artificial gravity as well. ).

It, along with Sif, was seriously damaged in 2525 by a mass driver fired by Loki from the surface of the planet, just before Harvest fell to the Covenant. The strands and parts of Tiara wrapped around Harvest, as per it's rotation. In a state of grief, Mack, Harvest's agricultural AI, ordered the JOTUNs to bury the strands of the Tiara and the space elevators, protecting them from plasma fire as Harvest was glassed due to the Covenant orbital bombardment.

Trivia

 * There are seven space elevators, this could be another Bungie reference to seven.
