I'm pretty sure that Alexander was a sealed Primal like Bahamut, possibly even an Eikon (which they recently made a distinction between that and primal).
It seems foreshadowed in the MSQ for sure.

They directly said that the Allagans had more sealed beings like Bahamut, and we should cautious because such dangerous things are out there waiting to be unsealed.
Lo and behold, the main raid of this expansion is primal that was seemingly trapped in a futuristic bubble.

It's not an Allagan raid, but this thing is definitely ancient and powerful enough to be sealed by the Allagans.
So it might have some differences with the Goblins as we know them now.
