Thordan was a Primal. Because he was given birth to by the prayers and aether of Ishgardians... Scions have faith in the WoL, but it's not the same thing at all, you're given power by Hydaelyn and Midgardsormr... Yes, you're turning into a deity, but like Odin, I think. A god among human and a human among gods.

And, probably, as the Ascians. The only difference being That you're said to be Hydaelyn's vassal while they're Zodiark's...
