We know a few things about the artifacts of the Dragonewts. We have a good idea about their weapons and armor. We know that their buildings seem to shift without notice as though they are more than half illusionary. We know that they use dinosaurs and demi-birds as beasts of burden, and have used three wheeled carts akin to their Dragonewt Rune to haul important dragonewts about on ceremonial occasions. What about their tools though?
Clearly dragonewts have scales and thus don't need clothes, and so their clothing is primarily armor or decoration. That is a lot of human material culture rendered irrelevant right there, as think of all the effort that goes into clothing people.
We also know that some dragonewts don't eat, as whatever they eat might be construed as an attachment, whether plant or animal, and so starvation for the sake of purity can be important. On the other hand, hunting and gathering is undoubtedly something that dragonewts, especially crested dragonewts are commonly encountered doing. So do they store their production? If so, do they know about making clay pots and working in ceramics? Do they keep water in urns? Humans drink for pleasure, do dragonewts? If so, what drinks do they make? Do they use water skins? Do the dragonewts use leather at all? I seem to recall that they have an interesting crop that they grow that is unlike those of the Earth Goddesses, but I can't recall its name.
The fact that the dragonewts have buildings implies that they have an understanding of working in stone and wood. I also believe that I have seen illustrations of Dragonewt ships in Heroes magazine years ago. Their unusual mystical roads are also interesting.
On the other hand, dragonewts don't use metal. This is not due to a lack of understanding of fire however. This does beg the question of where they find all the dragon bone that they craft with, and what its material properties might be. We also know that they make extensive use of obsidian, and likely use plenty of flint too, which is sensible as they can create impressively sharp cutting edges.
I am putting this up, because we know that dragonewts are said to be the most advanced culture on Glorantha, and clearly their advancement is not so much in the area of technology, but in their attaining of dragonhood. On the other hand, every urban civilization is dependent on material culture, so how far along have the dragonewts gone in what areas? I am looking forwards to your responses.
