This theory was mostly created do to snows ‘malfunction’ seen in the haxua story line, so take it with a some or a lot of salt.
As of this moment we do believe luno’s are actually a type of mecha puppet produced by the creator. Of course there a ‘cheaply’ created one most likely at least or easy to manufacture. This is due to the fact that they can malfunction, are short in stature, and have no known origin as of yet. Also because there’s a lot of them.
We also do believe that there are 3 different types of luno ‘classes’ that each luno is built for. Of course they have some natural traits that guide them to what their built for but they still do have free will to choose.
Leaders - self explanatory; snow maybe one or so we think at least
Passive workers - these lunos are usually guides, receptionists, scholars, etc
Active workers - these lunos are usually black smiths, weavers, explorers, thieves, etc
Also with this there’s a lot of variation to this theory and unknowns like…
-what would lunos be built from and how do they work?
-why were lunos created the way they were any why create them?
-why are lunos personality so one sided. (that being overly nice)
