I hate to burst your bubble but this image is overflowing with logical fallacies.Case in point: these victims supposedly died during Emergence Day of Sera, meaning they are at least 30 years old.Now take a closer look at this environments ashes:In arid desert regions the air over a hot desert may actually contain substantial amounts of water vapor but that water may not be generally accessible to plants, except for very specialized organisms (such as some species of lichen). 'Lack of water' refers to use by plants. The water that is actually present in the environment may be sufficient for some species or usages (such as climax vegetation).These remnants have clearly evolved in a continuously dry atmosphere, the only places on Sera having such a climate being the Jacinto plains, between the Aspho Fields at approximately 23°30' (23.5°) S latitude, and Landown in the northern hemisphere at 23°30' (23.5°) N latitude.The only part of this region that fits the bill as being susceptable to Hammer of Dawn attacks after E-Day is therefore one of the outlying plains along the outskirts of Jilane or perhaps Ephyra.As this satellite data shows, every year, very high quantities of dust storms are present across the entire landmass of this area -Right then, take a look at that first pic at the beginning of the post. Toward the bottom of the screen you will see a slab of stone material. The only stone economically feasible and available to Seran technology at the time would have been concrete, therefore we can safely assume that that stone is, indeed, concrete.Concrete degradation may have various causes. Concrete can be damaged by fire, aggregate expansion, sea water effects, bacterial corrosion, calcium leaching, physical damage and chemical damage (from carbonation, chlorides, sulfates and distilled water).Also, consider that this area must be relatively small to fit narrative purposes, and therefore, regardless of the location of this concrete in or nearby Jilane or Ephyra, significant wind-carried dust particles from the surrounding ocean,, will periodically come into contact with the surface of the concrete.Dust speeds up the erosion process, and combined with 30 years of intense dust storms, one can assume that perhaps 3 or 4cm of concrete by this time will have been eroded to the structurally weak concrete (III) oxide and even armored concrete(III)Such heavily eroded concrete would be so fragile and flakey, it would have literally been blown or eroded away by now. Only small stubs would be left of any such structure installed by Serans.Therefore we can surmise one thing, either Epic has completely dropped the ball on this, shattering the 4th wall, or someone else has been building and killing on Sera - approximately within the last 10 years...WTF?!?!
