: Architecture isn't my major, so please pardon my ignorance, but I get some
: Islamic and Russian vibes from the domes on the structure with the flags
: and the one in the background. The styling of the pillars on the building
: mostly hidden behind the middle structure seems out of place with the more
: advanced "mechanical" structures, perhaps indicating its age or
: reverence within its culture.

: I wouldn't go as far as to say that these are examples of Precursor
: architecture, as we know that a great deal, if not all of it was built
: with neural physics, which is susceptible to the effects of the Halo
: Array. However, if it is neither of the former Covenant, Forerunner, or
: Precursor, I would associate this architectural styling the prehistoric
: Human civilization. This is not without precedent. Heian, a planet
: encountered on a covert mission during the Great War, featured derelict
: cities and structures best described with the styling and abilities of
: eastern cultures that would more than likely not be present on modern
: humanity's own colonies.

The red flowing banners and even building structures to me could give off an Orient/Russian vibe, which combined with what appears to be a giant energy-sword wielding Sangheili statue could make it Sanghelios?
