Tidecasters were the other big school of mages. Waterworking and manipulating the moonlight - that's terrifying in a fight, drains your life straight to the one hitting you. They were pretty tied into the nobility along the coast, and did etiquette and navigation training for lots of people. Occulted Jade was one of the Five Wives who founded the Tiers back in the early years of Kyros - by the Overlord's calendar, they sailed west around minus fifty. Everyone was pretty surprised when she up and left, and took them all with her, rather than defend the Tiers. There were a dozen or two who stayed (true), but they fought in the Conquest and got killed (true), so there aren't any left (false).
Beastmen are weird. They're clearly smarter than animals, and cunning when they try, but at the same time they're incredibly stupid about anything civilized. Most of them in the Tiers were up in Azure, but they had tribes everywhere. Enslaving them is legal but usually stupid. Don't arm slaves, or take slaves who are permanently armed. Slavery's legal in Tiers law but it's not heritable, they have a fair amount of rights, and it's almost all done to settle debts - large numbers of rings in the hundreds of iron, or blood debts. A big fishing ship might have one slave, and he's basically like anyone else except most of his pay isn't his to keep.
Who knows, about Kyros? There were warlords in the east when the Fives Wives and Seven Husbands left, he was probably the winner. They didn't start hearing about him for a century or two, and mostly the Edicts.
Tunon's tried to tell everyone the laws but literacy isn't as high here as in the north, they will grudgingly admit that standardizing on a single script for the whole Tiers would have been smarter, if not using the Empire's script. They're different, and it's a violation of all custom and justice, but not awful for all that. The one about the overlord's name sure is full of himself, though.
It's been Regents for centuries. Nominally they're standing in for the two of the Seven Husbands from Stalwart who went back out to sea and didn't return, but Velkan's pretty sure that was made up later by the noble families and there's some other reason. (It will come up in passing that Janos and Rodica, though not Velkan, are distantly related to the Regent family.)
Cairn was an angry rotter. Seemed to hate everything and take it out on them. They hear his corpse is a hundred feet high now, he was only twenty then. There were rumors of the 'Wild Man of the Peaks' a couple decades back, probably the same guy, drafted by the Overlord. Walked through castle walls like piles of pebbles, but not Sentinel Stand, it's sterner stuff.
Besides the ones the Disfavored mentioned they know of Sirin, Archon of Song, she's with the Scarlet Chorus and controls minds. Janos heard she wears a locked headdress with a big gem in it, but he's not sure he believes it. Orphan Midwife, she's a good one, Sigil of Life is hers and she's been imprisoned for more than a century for letting her students spread it outside the Empire. Blood Ruin was the last Archon of War, more like Nerat than Ashe, and at least Ashe isn't him. Pox is the Archon of Ruin and plagued the whole Northern Kingdom last Conquest. Thousand Embers was born in Haven in Stalwart's year 60, he died in under a century but left a mercenary fire-mage guild in the Bastard Tier, the Chorus ate them up. Lightning, Entropy, Sorrows, Wounds, Fungus ("Really?" "Sage said so, swear on my shield."), Light, couple more Fire, Pestilence. Oh, and Runes, Mind Chisel, he's the first one anyone knows about because he invented writing a thousand years ago.
Mattias has a Sage handling messages, but most of them are out of the storm's area where they can send birds back and forth. Maybe look by the Oldwalls entrances, they like that stuff and the ones who're still resisting the Overlord are mostly the kind to try stupid things like find Oldwalls artifacts and use them blindly.
If the storm's still there and Stalwart's still suffering? Three-way fight, probably. Disfavored and the Unbroken captains both trying to break in and be the ones to hold the fortress when it's over, royal Unbroken fighting them off.
They want an independent Stalwart. There are only three Regents left (probably less) and they don't trust the First Regent, so they'd want a new government - they'd say militia elections like their captains now. Any other independent Tiers realms are bonuses. In principle Stalwart claims most of the Free Cities, but the only one it's picky about is Sunder.
No good maps here. Nor good knowledge of magic; they've heard of less than the Disfavored guy and disagree with each other about whether some things are possible. They're not ignorant but there's been a lot less military magic in their lives.
