I've been to the top of Bhaflau Remnants several times already, but only recently have I had the opportunity (after a wipe with low time) to survey the floor's curiosities.

Long-bowed Chariot is standing before a vacant chamber that contains a broken astral plinth. You can see part of the plinth hanging from above, but it doesn't appear as though the rest was snapped off or forcefully removed somehow. In fact, it looks like it's designed to be detached.

The remains of Archaic Mirrors litter the ground around the chamber. The first picture shows a couple mirrors still in their original spots. There are five gilded shafts in the top part of the chamber where Archaic Mirrors were probably once fastened. One shaft has a mirror, but the other four are broken. There's no symmetry to the spacing of the shafts, which is odd considering the otherwise impeccable symmetry of Alzadaal architecture. However, looking at the mirror on the right in the second, we can tell that not all mirrors are designed identically. This mirror looks as though it could span the plinth chamber from top to bottom. The beastmen's mirrors are also of a different design.
It's clear that the beastmen have been doing salvage long before us, having already plundered countless mirrors to use whenever they seize Al Zahbi's Astral Candescence. If eight mirrors and one AC makes a beastmen force a little tougher, imagine how things must've been back when Emperor Alzadaal was running the show: at least five ACs magnified by hundreds of mirrors in several towers throughout the sea.
Now what has become of the Astral Candescences? By comparing the crests above the doors of each remnants zone and a similar crest on the astral plinth, we can infer that Al Zahbi's AC is from Silver Sea Remnants. Bhaflau and Zhayolm are missing ACs, and I'll wager both Arrapago and Nyzul Isle are missing theirs too. The astral compass we got in TAU mission 9 hasn't been any help in locating these yet.
But if the ACs are missing from what was obviously once their housing, why are the Chariots standing guard? I suspect the ACs weren't taken by force since the Imperial army would have defeated Long-armed Chariot to take the AC, but the AC is already gone and LAC is still there waiting patiently to jack off our brains. This AC, as well as the others, must have been removed by someone (not the Aht Urhgan Empire, not the beastmen) with the clearance to bypass the Chariots, remove each AC and stow them away somewhere. Between this removing and stowing, the Empire managed to get a hold of what happens to be the Silver Sea AC.
So yeah. Make with the goddamn patches, Squenix.
Also, the windows on the top floor aren't sealed. You can hear wind blowing through the Chariot's room.
