I find this to be the more interesting part of the history.

Personally, I have little doubt that Omega weapon (or something similar) was utilized in capturing and imprisoning Bahamut, as the weapon was outright stated to have been designed specifically to deal with Elder Primals such as Bahamut. If I recall correctly, this information was revealed during a meeting between the heads of state in patch 2.3, in which they introduced the lore behind the Secure game-mode; though, I don't recall if they ever stated where they came across this information (probably off of one of the many allagan relics in the cartaneu flats).

Regardless, what I find more interesting is that since the fall of the Allagan empire, the Ascians have almost never provided similar technological support to any other species in Eorzea (Ultima Weapon being the one possible exception). They have chosen instead to work with beast tribes, and what little presence they've had in the more civilized cultures of Eorzea has been through manipulation rather than technology. Personally, this leads me to believe that the Allagans may not have used it in a way that the Ascians had considered, and that the Ascians eventually concluded that it was a mistake to give them such information (whatever that information may have been).
