The Burn

[ObsidianFire]

The Burn is still a huge unknown. The fact that there's still structures there seems to hint that whatever happened closer to "now" then further from "now". Given that the Empire is around 80 years old... I can buy Solus watching it get destroyed and then for some reason thinking it was due to a primal. Also... It's close enough to Othard for me to wonder how much "influence" Silvertear has on the aether. We've never gotten any confirmation that Silvertear influences all aether everywhere or just Eorzeas...

So... personal theory (headcanon) time... We know eikons were summoned in the 3rd Astral Era when the Crystal Tower was up, etc. Presumably, whatever blockage was on Silvertear Lake wasn't there at the time. Then the 4th Umbral Calamity causes an earthquake right at Silvertear Lake. The Crystal Tower and the entire Allagan Capital is sunk in a day. I'm wondering if the added mass of all that was what caused the blockage on the aether in Silvertear. In all the eras after that, we never hear of any eikons getting summoned. Then Midgardsomr breaks out of the lake and dislodges the blockage...

IDK, I find it more plausible that people tried to summon eikons in the wake of the Allagan Era falling and failing, rather then them just never summoning eikons again and never finding out about it...
