Sure, might as well.

Mattin is absolutely guilty, and wants to make a big deal about the jurisdiction issue and having left Anthel Camme, renouncing it entirely, and having been blessed for a hunt by priests of Bronzehill (which isn't official official, but of cultural/ceremonial importance) before they went.

His lawyer can try to make the best of it. Would he most likely have gone on a dragon hunt even if Vanda Nossëo had never shown up? That's important if you're claiming jurisdiction.

He would have most likely gone on a dragon hunt eventually. Whenever he decided he was done being Champion, or was getting too old. He quit here and now because of them, though.

Oof. Uh, given that Anthel Camme is now part of Vanda Nossëo and everyone in it is a citizen, did he do anything other than renouncing the championship to indicate that he was emigrating and not just going on vacation, it would help.

Renouncing the championship is a renouncement of the citizen's oath made to the King? He told his friends he was leaving forever and never coming back and gave one of them his house? He gave a speech about it in Bronzehill?

Okay, the lawyer can try to make a case off that. He'll want to call the friends and anyone witnessing the speech in as witnesses if possible.

Mattin has a bunch of names and describes which ones are most likely to be willing to do that.

The lawyer will go off to try to get ahold of them.

Some of them will talk about it! Yeah, Mattin was against Vanda Nosseo integration from the start, called them 'false stars', and kept saying he'd leave and not come back if there was a 'yes' vote and that everyone else should too. They can corroborate his long-time dream of dragon hunting as well, he's been talking about it for at least a decade. Here's the record of deed transfer on his townhouse to this other guy. And someone has been recording the speeches, Bronzehill priests will say he's a pious and earnest man who believes in self-determination and the freedom of choice.

Pious? What's the religious doctrine's influence on the situation?

There's two major sects in these parts. Both agree that the Masters placed Farmers, Delvers, and Enforcers on the planet and ordered them to build things to suit the Masters and destroy Chaos (especially dragons). Both also agree that getting rid of dragons and civilization and industry and martial strength are good.

One sect says that one should patiently wait for and obey the Masters on their return, for they gifted life and the planet to the Farmers (and has decided that Vanda Nosseo is not actually the Masters). These guys are on average opposed to membership, with a number of issues with multiverse priorities. 

The other, and the one Mattin believes in, is less popular and has gone far more towards "no masters but yourself!" with smatterings of freedom-kindness-liberty sermons and how everyone has free will. They also call for the end of nobility and slavery, and are (on average) supportive of membership, though people vary of course.

Their influence on the situation is that, if he wants to have nothing to do with Vanda Nosseo and to instead go live in the wilds and risk all the dangers of the wilds without being messed with, he should be able to do that!

Is there a religious leader of the sect Mattin belongs to who will talk to the lawyer?

They don't have a central organization, but local figure Priest Ergen is happy to talk to the lawyer in a tavern or his house or a field or wherever really.

"I've been corresponding with him by email. Thank you for going through the trouble to find me, especially if I can help."

"Of course. Religious freedom isn't normally a murder defense, but it might help me make a jurisdiction complaint stick; can you tell me what the faith's attitudes towards dragons and to the rule of law are?"

"The rule of law is inherently enforced by the threat of violence, direct or implied. While rule of law can and does create many benefits, the root of it is in violence, and some having more power than others. This is bad, since it means people live in fear and find their choices greatly constrained by other people. Human beings seek order, we were designed to, so seeking the absence of rule of law is an extreme position in the faith, but an understandable one. We are surrounded by invisible walls- The tacit agreements of society, the circumstances of our birth and raising, the limitations of the body. We feel that the law should make this threat less salient, should raise as few new walls as possible, should seek to minimize the amount it impinges on the soul's inherent freedom, which Vanda Nosseo has done with aplomb, but it can never be fully excised so long as law exists at all."

"Dragons are far more powerful than human beings. Animals and insects are mostly less powerful than human beings, but we should not resent any being its desire for freedom, even those less than us. But dragons have immense personal strength and power, and behave like Kings lording themselves over a Kingdom. Attacking who they wish, taking what they wish, never answering to any but a more powerful dragon. They can be plied with tribute like a serf offers up his grain, offering your livestock, or jewels and gold, and this will sometimes save an unfortunate who has encountered one from the maw or the flame. But that is bowing down and hoping your lord and master does not strike you down. Thus dragons should be fought just as much as a slaver or unjust king should."

"Thank you, I think that will help a lot."

Next he is going to do his best to track down Snake Below Pines's next of kin or best friend or whatever the closest dragon equivalent is.

The pack of wolves that reported her death is not very talkative. Her neighbors (as one mentions to an envoy) are mostly thinking about taking her territory but holding off because she might come back and it'd be embarrassing or unfair or something to have done that while she was gone. Not really friendly. Some conjuration can find her biological parents; Father's also dead, mother lives way over there in some savannah and isn't interested in leaving it but will talk to people in exchange for interesting stories.

Well. This lawyer happens to want a promotion. He will get himself couriered to the savannah and read her the news or Beowulf, her choice, to get a reasonable guess about what Snake Below Pines would have thought about the situation.

Dragons can telepathy directly at non-elves, it's just harder on both ends. It can be confusing and a bit overwhelming.

Oh, her child was slain by the humans? Regrettable and ugly business. Sparkwind Flow knows little of who her daughter has become over the years, aside from the occasional visitation. She was certainly upset and angry they were in her territory, since humans are dangerous and smell bad and mess with nature. Though perhaps she had decided to take advantage of them by letting them hunt and then scaring them off? That's what it sounds like. Foolish plan if so, playing with dangerous forces. Humans are the cleverest prey, one must always be careful of them. Smelling poison on the meat the second time surely sent her into a righteous rage, that sounds completely accurate, though a more cunning dragon might have stalked and planned their deaths rather than attacking immediately.

Is it true she can pay to have her daughter returned? She's not sure she should, but gathering more information is the first step.

They haven't tested resurrection on dragons yet but yes, in principle. Why isn't she sure she should?

This is hard to translate and very confusing!

...Dragon religion, basically, saying that if she died it's because she was meant to die on some level.

Huh. Well, he doesn't have a very strong opinion about that, he's a lawyer for the murderer, but that's interesting to have on background.

Sparkwind Flow doesn't like him much (because of what he represents, a function of the dizzyingly complex society that is trying to worm its way into the world), but reading some Beowulf and listening to her acerbic commentary on it will leave her satisfied with this exchange.

He took a Beowulf class in college and finds it fun to dramatically read.

He doesn't even have to speak out loud, though it is amusing.
