So, the Fractal Continuum (spoilers)

[Fenral]

You mean the 3 statues? on the quests of ravana/bismark ex, the npc said that gose beings were captured by the allagans. Its no so big surprive to find them on that "stone" state, we dont know what kind of method the allagans used on them.

Binding coils, like the ones on poor Tiamat.
