Whats up with the Sangheili ruins in Halo 5?

During Mission 8 Vale states the Pre-Covenant ruins “were already ancient when humanity built the pyramids” yet a short while later you can encounter a carved mural of the Writ of Union which was the formation of the Covenant and the end of the War of Beginnings.

This raises a few questions though. The sangheili were already a space faring race when the Writ of Union was signed so why would a sangheili carve a mural of it into some stone walls? What? That makes no sense. Not only that but the Writ of Union was signed in 852 BCE while the oldest of the Pyramids of Egypt the Great Pyramid was finished in 2560 BCE. Thats over 1700 years before the Writ of Union.

So was this stone complex occupied for 3000+ years before being abandoned?

Did some Sangheili come back to it almost two millennia later to crave in a depiction of the Writ of Union? Why? This makes no sense. Thats like if humanity discovered aliens tomorrow so someone decides to carve a mural of the event in the Arch of Constantine.

Sunaion was a pre-Covenant religious site as well. Just because they’re old doesn’t mean they won’t go back to them, or put heavy value on them.
These ruins were probably important to the Sangheili for various reasons, and they decided to keep the connection going by sealing the Writ of Union into the link to their past. Symbolic.

We wouldn’t go back and write things on Mayan ruins. But if our civilization was Mayan, as if they had gone out and conquered the world, those ruins might be important enough for us to revisit today to record what’s happening too. Add a new chapter into what is seen as a recoed of history. It might be stone, but still a record.

Yeah. Also, the Sangheili didn’t immediatly become Tier 3 after the Halo Array firing. Even though they advanced really quickly, things like this take time. The real Swords of Sanghelios, for example, was a order which existed before the Sangheili were spacefaring.

He means that technically humanity and the Sangheili started off on more or less the same footing since they were both repopulated after the Array fired, but the Sangheili it appears progressed much more rapidly (honestly, this is probably due to the abundance of palpable Forerunner tech sprinkled throughout Sanghelios compared to the scant pieces on Earth).

The Sangheili to me advance more with technology, but also stick to some of their old ways like if with Athens keeping the Pantheon, instead of removing it or Rome not removing the Coliseum.

There is however a difference between keeping something and altering something.
