Oh, and the Nael van Darnus *we* knew was in fact Eula Darnes, Nael's elder sister. The real Nael died because of a mission his father sent him out on. Eula was the one obsessed with Allagan technology and history, which she saw fit that the House Darnus was her key to earning the secrets of Allagan Empire. So Eula was the one under the mask as Nael the whole time, which is why in Coil, Nael is unmasked as a woman. This is Eula. Her aether after the events of 1.0 was absorbed and twisted by Bahamut, and he used her essence as a puppet against you, the Warrior of Light. Which is why she also took on the body structure of Bahamut.
