How do calamities work, again?

[MistakeNot]

Small question, do we know if bahamut event caused a rejoining or was it suppose to absorb the first?

I don't have quotes at hand, but from what I understand the Seventh Umbral Calamity was indeed a Calamity with the associated Rejoining.

Specifically it was the (actually successful this time) Darkness attributed Calamity that took I believe the 6th Shard, maybe 5th. It was the last one shown being absorbed when we got the explanation on Calamity stuff this xpac.

Given what we know I'd say the normal elemental attributes were easier for the Ascians to pull of compared to Dark and Light attributed ones, thus why they didn't attempt another Darkness one till after those were done. Light was probably the hardest for them to pull of, and given what little we know of the First's Ascians they may very well have sacrificed themselves to help get it started. After all if the Rejoining works they'll be alive again anyways.

I think the Rejoining occurred when Bahamut started breaking free of Dalamud. For millenia it had been fettered by the neurolinks, clearly designed to withstand the Dreadwyrm's power. Once the Seventh world started rejoining, that cascade of aether probably enhanced his megaflare to the point of overwhelming the satellite, causing Dalamud to violently disintegrate. And since the Seventh shard was overaspected to Darkness -- all six elements astrally charged -- this also augmented the secondary effects of the impacting debris and rampaging primale to causing powerful megatsunamis, rifts opening up in the earth, forming glaciers, and other crazy effects.
