About these "calamities" and "Astral/Umbral" eras...

Ferne actually confirmed the column of light at the Battle of Silvertear Skies (i.e. in 1.0's original opening FMV), really was the Primals being released from confinement, and that until that time they had been sealed within the lake.

Did he? I might be blanking on something big, but the only official mention of the seal on Silvertear Lake that I can recall at the moment was one that specifically avoided confirming that the primals were sealed there, which is the only reason I remember ever questioning the primalsplosion as a mystery to begin with.

Though the great dragon is able to destroy the Garlean flagship, he perishes in the process, and the seal which he protected (guarding the concentration of aether beneath Silvertear Lake) is broken, allowing the beast tribes access to this energy, which they use to freely summon their primals (as taught to them by the mysterious paragons). The Garleans, having lost their flagship and sensing the presence of something more powerful than their remaining forces can handle, retreat back to Ala Mhigo. Meanwhile, with the fall of the Keeper of the Lake, the aetherial balance in the area gets thrown out of whack, transforming the once lush area into a crystalline wasteland—Silvertear Falls now dried up.

Skimmed the rest of the old post just for fun, and this now stands out to me where it didn't before...

Do the dragons of Dravania worship a primal? And if so, who? Is it Nidhogg? Midgardsormr? Someone else?
Yoshi-p dropped a few bombs last week revealing that both Midgardsormr and Nidhogg were not primals, but dragon ‘kings.’ However, he also revealed that the dragons are a beast tribe...and that beast tribes have their own gods (primals)... So...

I used to think this was a hint about Bahamut, but we now know Bahamut to be the first of the Meracydian brood, deified in desperation to save them from Allag advance. But this is answering questions about Dravanians. Did the Dravanians do their own bit of worship and summons? Could this be related to the mystery primal that halted the Garlean advance!? Probably not, but ohoho baseless pot-stirring!
