Interesting theory, consideringkilling the Ancient Dragon only drops a Giant Soul, while the body in Brightstone Cove drops the Ancient Dragon body.
The duke in Brightstone could be Aldia as well, but I like the Navlaan theory, some interesting text on his helmet.
"Hood worn by a chaos sorcerer.
He calls himself Navlaan, now."
Also, the Scraps of Life Hex
"An esoteric spell created by Navlaan, the infamous exiled sorcerer. Awakens the souls of the long-buried dead.
The heretic Navlaan was executed along with his entire village, and the mere utterance of his name became a crime. Some say it was because he sought to restore the banned art of resurrection."
OOOOOOOOOOH SHIT DAT HELM DESCRIPTION, also
Giant Soul? Why is that? Could Aldia have put it there for you to help you fight his brother then? If there's a dragon body with an Ancient Dragon Soul, then it's pretty much confirmed that the one we talk to is either an illusion or, as the hex might suggest, a ressurected version of the Ancient Dragon, using the Giant Soul to replace his original Soul, since that couldn't be replicated?
Though the fact that the body is in Brightstone (is it near the head I assumed was Seath's?) goes back to hinting that Tseldora and Aldia are either connected or the same person.
Well, since Navlaan is definitely a fake name, what if Tseldora = Aldia = Navlaan? Maybe Lord Aldia Tseldora was his name or something like that, Navlaan is just a pseudonym, so it doesn't get too convoluted as I first thought (the same guy being 3 different guys would be too much, 2 is acceptable).
