Temple (Installation 05)

Summary
The temple-like structure that the Prophet of Regret occupied during his brief stay on Installation 05 was located in the center of a massive lake. The only way to way the temple without a dropship or aircraft was by taking a route through a series of underwater tunnels, over bridges, and by travelling on anti-gravity gondolas. The purpose of the temple-structure was never discovered because it was destroyed by a Covenant Battle Cruiser shortly after Spartan-117 disposed of the Prophet of Regret. However if one takes one's time through the start of the level Regret, one is able to hear Cortana's various thoughts on the structures. Such comments made are, "This lake couldn't have been formed by volcanic action, so it was either built this way on purpose or formed through some other cataclysmic event," and most intruigingly, "I think the Forerunners built these new structures over the old ones, to protect them, honour them."
