The White Raven fragment was a bigger spoiler back around 2.2 as long as you knew a bit about the pre-2.0 story. Anyone who has cleared Turn 5 has seen Bahamut's head... That the gear is called Dreadwyrm and the crafting item is a fragment of his heart (which we also see in the T5 ending CS). Not unusual that the Binding Coil of Bahamut would eventually wind up with Bahamut themed gear/items...
