Regarding the 'soul' of an Eikon/Primal
I've been wondering about this for a while, in case it becomes a future plot point.
Take Bahamut. There was a historical Bahamut who was slain and then summoned back into existence as a Primal. Would the Primal Bahamut actually possess the same soul as the historical Bahamut, albeit corrupted into a primal form, or would have the Primal been a completely new entity shaped by his worshippers' belief? If the latter, would that mean the original Bahamut's soul is still floating around somewhere in the lifestream, if even that, since dragons aren't exactly from this world?
One could extend that same question to Varis and Anima. Anima used his body, but is Varis' soul part of the equation in any way?
I am not sure if this was ever fully explained or even brought up, so this inquiry is here in case anyone knows more.
