This universe has a civilization of humans! And some other things. It's not crowded in the way Edda is but it's not just the one planet either. The humans might be easiest to start with. They're on that planet over there, it's not Earth but it has very Earthlike conditions and bronze-age humans living in cities and villages dotted across two large continents. Depending on how thoroughly any prospective visitors look they might find other things before visiting.
"...I think I can't say it's all one thing and none of the other because the soul is messy, and I'm in my own head not his. I think he would have left Vanda Nossëo no matter what, whether a hunt was convenient or not. I think his desire to kill a dragon is not new, and he would have dragged us all out to do it in a few years even without you all. I think he knew it was likely you'd try to arrest him for it anyway, and decided it was worth the risk. Whether he did this because of Wilder religion, or out of spite, I have no better idea than you. Both are things I've seen from him before."
The judge mulls it over for a bit in her office and then comes back out.
She says he is to be dropped with whatever possessions his erstwhile companions agree are his alone, in the place he was when arrested; the dragons and animals in that area will be warned about him; if he enters Vanda Nossëo territory again including by any territory joining while he's there he is still wanted for murder and will need to serve out a delayed five year sentence, he is not free to walk around any part of Vanda Nossëo or polities with a mutual law enforcement agreement with them, he should be advised that the dragons are working on joining - but as long as there's anywhere he can get to that isn't interested in having laws against murdering dragons, he can live there.
The stuff can be divided straightforwardly, though everyone claims the dragon head, which they eventually agree can just be destroyed.
Mattin is dropped off there in the mountain foothills, gets his bearings, and then hikes north, having a slightly difficult time of it since all the animals avoid him. The whole series of trials has gotten a fair bit of attention on Spirit, with quite a bit of division. In the weeks after Mattin goes on a quick tour of the Metal Kingdoms (which is looking less likely to join by the day as more cosmopolitan people just emigrate to neighbors that have gotten colony planet land), gathering a small following.
Mattin gets more money from friends and coreligionists to pay his lawyer a bonus, before they go.
The group makes speeches and blog posts about the joys of anarchism and buys a bit of distant valley from the King of Bronzehill and puts up lots of signs saying "The state of Wilder. The only law here: Do as thou wilt." and starts building in the unremarkable bit of land. Several of them bring in modern amenities like magic songs, though.
The dragons' Grand Moot has been firmly set for eight months from now. Next spring, for the majority of the dragon population. Dragons don't move that quickly. It seems like all the progress that can be made until then is more discussion with individual dragons, animal-spirits, and incorporeal-spirits.
Solomon the shaman goes through student interviews and picks based on intuition more than anything concrete. For the first actual lecture he has eight people (the first of a few sets of them) meet in a greenhouse he's bought with the grant money and filled with Spirit-native plants, two minutes' walk from a bus station. There's a clear spot with a ring of cushions and scattered chairs, he encourages everyone to sit.
"The foundation of shamanism is a spiritual awareness and understanding. You need to build an intuitive understanding and awareness of the world, and then of the principles and flows of this magic, in the shamanistic tradition. Now, I've taught two apprentices before but they were starting from a very different place, so I'll appreciate your patience. What do you all know already about shamanism?"
"There are some similarities," he nods. "And differences. Shamans often focus on the four classical elements of earth, water, air, and fire. We are in tune with nature. But we aren't going to be transforming into animals any time soon, unless you go to Cube. Most shamans spend a lot more time watching and listening than doing. Spirit natives can learn it for certainty, and this class is sort of a test for whether it can be spread- I think it likely, but one never knows for sure."
He smiles and makes an approving gesture. "To spirits. Most of the intermediate work is listening to them, working with them, coming to understand them. By learning to do what comes to spirits naturally, you gain the obvious, outward signs of magic." He lifts sparks from his staff with a snap of his fingers. "My plan is to start off each session with a bit of lecture-slash-discussion, and then guided meditation. So. What are the four elements? Fire, earth, water, air. But I don't mean 'the process of combustion' and 'oxygen and nitrogen molecules'. What does fire mean?"
"It'll vary, yes. Everyone thinks a little differently. The thing I'm calling fire is - again - not a literal, actual fire. It's the magical element of fire, which forges metal and lights the way, which comforts and holds back the cold, which burns everything it can reach. Fire can be civilization, warmth, destruction. Anyone else?"
