Strigoi

I'm new here so I don't know if we can post stuff from secret history yet, but I remember a passage from that. When preservation was talking about Kelsier burning Malatium: "You got a glimpse of the spiritual realm, then? His connection and his past?" Since Malatium is a mix of Atium and gold I'm pretty sure it means that burning gold can let you see yourself from the spiritual realm.

I think the premise for this question is flawed. That's because Aons aren't actually the focus for Sel's singular Magic system, but it seems like landmasses are since you need the shape of Arelon to power AonDor and Maipon's shape for Forgery. I believe that the equivalent of Atium/Lerasium in this situation would be something in the land like stone that would be useful in manipulation the Dor; such as Soulstone. Pretty sure somewhere in The Emperor's Soul Shai mentioned that Soulstone fell from the sky (when devotion and dominion shattere maybe?)

This post seems dead but I might as well add my 2 cents. The way I see it the specific gems and the essences that a soulcaster can use stormlight in those gems to turn things into are the only two things that another shardworld would logically have in common for this theory. The surges seem to be Honor/Cultivation's influence with Roshar's essence; Lucentia. Like how burning steel gives you investiture from preservation that only allows you to push metals it seems like absorbing investiture in the form of stormlight with an honorspren only allows you to manipulate gravity and adhesion. It's most likely that poeple attributed surges with the essences because they're looking for a connection that isn't there just like Scadrians putting Atium and Malatium on the table of allomantic metals when they shouldn't have been there. Along the same lines I think the the divine attribute/secondary attribute are just things the Rosharians attached to the essences because the Knights radiant personified those attributes and don't have anything to do with essences at all. The bodily focuses seem to just be symbols of the essences and thus other shardworlds don't need to have them. Though I do disagree with Roshar being more or less important than the other shardworlds because of its essence of Lucentia. It seems to be a coincidence that this was the place where people first had the idea of surges (because of soul casting) and while the idea of it being a prism for investiture was an interesting idea I don't think this is the case (though I can still be proven wrong on this point). But it does seem like Roshar will be important for other reasons, since it is where the fight to defeat Odium is taking place.
