That Taddeus Cosma guy fascinates me. He's a time traveller+possibly from another reality, representing a certain organization he's not allowed to name, wearing Dwemer armor and a stupid hat. I have half the heart to think it's possible Falion met someone of this organization and mistook them as Dwemer, as it's very possible with an elf. Or they could actually have Dwemer members, if the armor is not meant to simply appear 'futuristic'. But I think it's more likely Bethesda & Zenimax did not mean for these two things to connect whatsoever.
I find the "stupid hat" comment very hilarious here because it tells us more about the sneaky bastard than literally anything he says.
He's wearing the Imperial Mananaut Cap & Goggles, Imperial mananauts being a mysterious group that existed during the Second Empire that were tasked with the exploration of reality, namely through researching the planes of Oblivion and trying to reach Aetherius.
So yeah! Time and space explorer from either the past or the future.
