If we accept "Arcturian Heresy" as the basic (though not absolute) source of Talos origin, then we still have a question about Talos of Atmora. He
did exist because we have Elk's drawing.
And also Greybeards' stories. Maybe Hjalti was
in fact from Atmora? I don't like the idea that the only Atmoran element in Talos was half-dead Wulfharth.
Could Talos of Atmora be in another reality (where Vivec was god), which fused with Hjalti's by Dragon Break?
It greatly reminds me Vehk-and-Vehk situation.
Voted for Nord, anyway. =P
