Temple (Installation 05)

Were you looking for the structure from Halo Wars or the Temple of the Abiding Truth?

The Temple was a Forerunner structure located in the center of a large artificial lake on Installation 05. The structure was occupied by the Prophet of Regret during his brief stay on the installation. The only way to the temple without a dropship or aircraft was by taking a route through a series of underwater tunnels, over bridges and by traveling on anti-gravity gondolas across a system of towers and other structures across the lake that surrounded the structure. The purpose of the temple structure was never discovered before it was destroyed by a Covenant assault carrier shortly after the Master Chief assassinated the Prophet of Regret.

Architecture
The temple is a symmetrical structure, with two gondola docking places. It rises out of the water on six legs, and looks similar to Epitaph. There is one main entrance to the interior of the temple, and a hallway that leads to two more openings. Through those openings is another large room. In this room are two small doors in the far left and right sides of the walls. They, along with a large ramp leading to a door are the entrances to the main hall.

In this large room, there are four doors in the walls which lead to small rooms. There are walkways, and three levels. On the ground level there are various blocks, and a pond. At the far end there is a raised platform where, in 2552, the Prophet of Regret conducted his sermons. Regret was slain in this room by John-117 in November 2552, and the temple was destroyed by an assault carrier's energy projector shortly after.

History
Following his retreat from Earth, the Prophet of Regret's assault carrier Solemn Penance exited slipspace near Installation 05. The Prophet immediately deployed ground troops to the surface of the installation while Regret situated himself in the temple and immediately began his sermons. He was supported by a large number of Sangheili Honor Guardsmen and various other Covenant troops. The exterior was fortified with Shade turrets.

Unfortunately for Regret, his ship had been followed by the UNSC. Frigate In Amber Clad had managed to follow Solemn Penance into slipspace. The human ship deployed a large force of ODSTs along with Spartan John-117 into the surrounding area with the objective of assassinating the Prophet Hierarch. Despite the Covenant's best efforts, the UNSC force managed to clear the ruins around the lake and eventually the other structures in the lake were cleared of Covenant forces. With the human 'demon' closing in on his location, Regret readied all forces in the temple for the Spartan's inevitable arrival.

The Master Chief eventually made it to the temple himself, clearing out the many Shade turrets on the exterior before moving in to the central chamber itself to confront the Prophet. The Covenant Holy City High Charity along with its vast defence fleet exited slipspace above the temple. The fleet deployed multiple waves of Phantom dropships to reinforce Regret, but these were ultimately called back by the Prophet of Truth. Despite fierce resistance from Regret's Honor Guards as well as the Prophet himself, the Spartan was able to board Regret's throne and beat the Hierarch to death. Immediately after, the fleet prepares to fire on the temple. The Master Chief barely escapes, diving into the lake as the temple is completely obliterated by an energy projector.
