As for the continuous mention of a "seal" on Lake Silvertear, I don't actually know where that's coming from. As far as I know the lake is spoken of as the font of aether for Eorzea and the explosion we see is a large amount of aether washing over the realm.
Middy guarded the seal over that aether fount. How ever I'm not sure that was actually sealing the primals or was stableizing the aether in Eorzea.

Other than a slight reference to the seal being destroyed in the battle of Silver Tear Skies there was no mention of it even in 1.0 about its origen or purpose.

Not that I recall anyway.
