Do Ascians dream of voidsent sheep?

Zenos, of course. The Wiki specifically states that he chose to take Ala Mhigan elements such as the fabric and belts to adorn his armor with. That means that the red skirt is supposed to also be protocol most likely. No draconic elements besides the flame motif, no Garlean sigil either, whether it was meant to be as simple as a pure red with flame motifs, or he specifically had it done that way, we cannot know. Had he not worn the crown on his helmet, you could pass him off as a Legatus. Still, it's interesting to look at the style and way that he chooses to wrap the Ala Mhigan fabric around his waist, as it looks very similar in fashion to Solus. Varis on the other hand has absolutely no other extra elements, his attire being fully and entirely Garlean, very neatly worn, it just displays his pride as being Garlean and the Emperor.

Also let's not forget the fact that Zenos chooses to leave the helmet (implicitly the crown as well), once he deems us interesting enough and brimming with potential. He's never seen wearing it again, which honestly feels like the biggest symbol of him belonging to Garlemald, as he too has no royal sigil inscribed within his clothing. And we know he outright tells Varis he never intended to rule....while also never being seen with said helmet or crown again, even within the palace walls.

I've already mentioned in another post how with ShB and EW later on, he sheds the symbolic Garlean elements much like a reptile sheds its skin, so in the end you have a man that has nothing tying him to his Garlean identity, besides his Third Eye, which could also very easily be hidden away as many of the reformed Garleans have done.

No Garlean imagery, no draconic symbolism, not even the very bright Garlean red, no outright armor. It's instead lighter fabrics, with some semblance of metallic elements here and there. Can't exactly tell what the motifs on his shoulder are, but they feel floral (I can be wrong). His outfit changes are a very visible change of identity still, and choosing to entirely separate himself from his Garlean descent.

Also thinking back to him finding Shinryu a perfect specimen.

Wyrm.

The symbol of the Garlean crown apparently. And becoming such a symbol himself, he did what neither of the Emperors could, who instead could only adorn their armor in a dormant symbol of it, pretending to be just as powerful.

And then at the end of it all, he used the very same symbol and specimen to indirectly save the whole world through saving the WoL. The Wyrm no longer attacked, but offered support, trust even, since WoL got to ride upon its back.
