2.4 Main Story Revilations *SPOILERS*

[TinyRedLeaf]

I'm preety sure Midgardsomr was the gaktekeep that made the Primals Sealed Evil in a Can. His death released the primals. Therefore the Asceans could have instigated the Dragonsong war (or at least escalated it) so that the Holy See will get Midgardsomr killed and the Primals could be summoned

The explosion of the Agrius on Silvertear is what freed the primal. Midgardsormr was the keeper of that place, not the seal itself..

Midgardsormr was, I believe, the Keeper of the Lake and the protector of the seal. And if I'm not wrong, it was a vast store of aether that was released, not the primals themselves.

The aetheric fallout from that disaster is the cause of the purple smog that chokes Mor Dhona periodically.

I can't remember who it was, but there was someone who speculated in this forum that Midgardsormr could have been forced by the Allagans to guard the aether stored within Silvertear Lake. Given their extensive mastery over dragons, I thought it a plausible theory.

Recall that the Crystal Tower is right next door, and that it appears to be a facility for collecting solar energy and converting it into aether. All that processed aether had to be stored somewhere.

And the Allagans also appear to have had a bad history with primals. They first encountered them during their attempted invasion of Meracydia. And one of their most gifted mages, Wiyu, died in the attempt to seal Odin.

The Allagans went on to develop a number of counter-measures against them, from summoners to the Ultima/Omega Weapons and Dalamud.

The locking away of so much aether in Silvertear Lake may also have been a counter-measure, to cut off the necessary fuel for summoning, as it were.

I wonder when Shiva lived, and how long the 'heretics' have existed.

Possibly a thousand years or so, since the Dragonsong War is said to have lasted at least that long.

As a small side-note, I also found the revelation of Sastasha (Hard) to be very interesting.

I haven't completed Sastasha (Hard), so I had to glance away from your later sentences. I'd say only that I had a good chuckle in seeing the 2.0 version of a certain ill-fated party, whose leader lost his head.
