Old Night historical timeline

I've decided to create a new tag, OLD NIGHT which will refer specifically to setting stuff, as opposed to the mechanics of the game Shadow of Old Night. That name is kind of long, and I don't like using the acronym SoON because it looks silly. I'll also use THREE REALMS+ since I can't just use Three Realms anymore after deciding that Lower Kurushat wasn't just a "part" of Baal Hamazi, Hyperborea might get some development after all, and the Corsair Coast and even Nizrekh will all be brought in to scope for development.

Anyway, I've said before that I dislike long detailed timelines of settings; I don't find them all that interesting and even more to the point, I don't find them useful. But abbreviated, brief timelines have neither of these problems, and they just kind of articulate in a vague, handwavey fashion what happened in what order. So, here's my first stab at making one for Old Night, using the new tag for the first time.

I don't want to put dates, even approximate ones; just an order.

• The Three Realms+ are settled by Atlanteans. Vast hordes of Atlantean slaves harvest lumber, work mines, and farm the territory. Thurses and orclings are here in small numbers, but are barely more civilized than animals; most are killed off. Orclings are pushed southwards, and thurses survive only in the deepest forests.
• Atlantis is destroyed. The slaves rebel. Most are killed, but their masters are all killed. The handful of remaining people are cursed and gradually sink into stone age barbarism. The descendants of the Atlantean slaves become the Grendling people, and continue to diminish.
• Hunter-gatherers from the southeast push into the area. Their population is most dense in what is now Southumbria, but they spread across the entire region. Their descendants eventually found the Kin Twilight kingdoms of Halych, Permia, Pezhek, Vuronezh, Leszek, and more. 
• Most of the east is combined into the single kingdom of Kinzassal. 
• In the far western reaches of Kinzassal, Tarush falls from the sky. This leads, eventually, the downfall of the kingdom. New, darker kingdoms with vampires ruling openly form in the southwest. This is the foundation of Tarush Noptii. Others flee north and become the Drylanders. Some few remain in the east but diminish and sink into barbarism, their numbers greatly reduced. These are the Tazitta tribes. Some go south; they mingle with indigenous people on the coast and become the Pallaran people of the Corsair Coast. 
• The kemlings are born among the Drylanders on the far northwest peninsula. Over the course of a few generations, they conquer the northland, extending to the borders of Tarush Noptii and eastward to the Darkling Sea.
• Nomadic war bands of Northerners start to filter into what later becomes Lower Kurushat. These war bands are later followed by the Imperial might of the Kurushans. Kurushat and Baal Hamazi go to war. Baal Hamazi retreats from the far east, where they only lightly settled. 
• The great wars of the Indash Basin exhaust the strength of both empires. Kurushat retreats, although some remain, to become the orphan petty city-states of Lower Kurushat, and Baal Hamazi retreats completely to the west of the Rudmont Escarpment.
• The Indash Salt Sea had been retreating and drying out for years; the land to the south but north of Tarush Noptii is renamed the Boneyard due to the unburied soldiers from Baal Hamazi and Kurushat who's bones litter the ground. The Indash retreat accelerates; the Boneyard turns into pinyon-juniper dry forest, or even drier full-blown desert, and the northern part of the area becomes a vast salt flat. Baal Hamazi and Lower Kurushat are somewhat cut off from the rest of the Three Realms, and the Great Northern Road falls into disrepair. 
• The earliest Colonists come from farther east. Carlovingian settlers mostly pass over the Hill Country (although they shed a few homesteaders, ranchers, etc.) and go to war with the weakened aristocracy of decadent Tarush Noptii. 
• New waves of Colonists settle the Hill Country, establishing the Hill Country that we know today; the Carlovingians topple the Tarushan government and establish themselves as an aristocratic conquerer class, calling themselves the Timischers. But Zobnans come into the northern part of the area from Hyperborea, and settle the city-state of Lomar. They have friendly relations with the early Hill-men of the north.
• Final (smaller) wave of Colonists join the Hill Country, mostly from Culmerland, Normaund and Skeldale. The route is blocked by supernatural nevernding raging dust storms and other hazards that remain to this day and more colonial travel is stopped.
• Baal Hamazi collapses into its current anarchic tribelands and city-states status.
• Due to prosperous and relatively peaceful years, the population of the Hill Country continues to increase, leading to the settlement of formerly abandoned or empty regions on its borders. The East Marches and Burlharrow are first established. The first orclings start to come up from the south in small numbers.
• Bucknerfeld is established. Hill-men start to spread into the Cactus Balds, forming the West Marches region. The East Marches continue to grow. The Great Northern Road is extended between Bucknerfeld and the East Marches, passing through Lomar, although it is still in disrepair to the west.
• The Hill-men continue to make commercial contacts with Baal Hamazi and Lower Kurushat; the first steps to re-establish the Great Northern Road westward are taken. Larger migration of orclings; the Chersky Island colony is established.
• Current day. None of the Three Realms+ are truly isolated from each other, although big distances of mostly empty land still separate all of them from each other.

Pallaran corsair

You'll notice that many of the Old Folk of all three of the Three Realms+ are ethnically related, but so long ago that most semblance of relatedness between them have been lost. The Drylanders certainly don't look at the Tazitta tribes, the Tarushans or the Pallarans and see themselves as distant cousins, nor are their languages very similar anymore (this is especially true for the Pallarans—the rest of them have a kind of Balkan Romanian and Slavic vibe, whereas the Pallarans are Romance language like Romanian without the Slavic influence.) The Northlanders are a completely different ethnic group altogether. The Colonists are also different groups, but more related ones, and their languages and cultures are more similar to each other. They recognize their distant relatedness, although see themselves as separate (the Brynach are the exception, but they are pretty heavily integrated into the Hill-men ethnicity. Most of them are Germanic; the Culmers (Hill-men) are like Medieval English, the Timischers like Medieval Austrians or Germans, the men of Skeldale like Medieval Scandinavians, the Normaunds like Medieval Normans, etc. The Brynach are Medieval Scottish, mostly. But that's more on where I get their names and how I describe them than anything else.

What languages would be actually spoken somewhere? Hamazi, which is a Drylander language with many dialects varying by tribe, Northlander which is from Kurushat, Tarushan (in small numbers as a minority language), Pallaran, Tazittan, Nyxian (in Lomar; the Zobnans lost their own language and much of their original culture, but the Nyxians are more ethnically aware), Orcling, and of course, Common, which is the language of the Hill-men. The thurses have their own savage tongue as well, although few outside of their race know it or are even capable of speaking it even if they do because of their vocal anatomy.

In Timischburg, the official language and the most that you'll hear is also Common, but with an accent. In both Baal Hamazi and Lower Kurushat, as the original Imperial powers have disappeared and left anarchic tribes and lower city-states left, they've largely embraced Common too, and it's still the most common language in those areas too. Mostly only the tribesmen in Baal Hamazi refuse to speak it. In Baix Pallars, along the Corsair Coast, Common is also becoming more ... well, common, because people from the north have been moving into it in large numbers, and even without that, maritime trade has brought the language as the language of trade to the area. 

UPDATE: I don't know if I did this subconsciously or not, but the people who later split and became the Tazitta tribesmen, the Tarushans, the Drylanders, and the Pallarans are analogs to the way Tolkien did it too; the Haladin and their kin east of Beleriand, like the men of Enedwaith, Minhiriath, Bree, the White Mountains, Dunland, etc. The Colonists are like the second and third houses of the Edain; Beor and Marach (later renamed to Hador) who were closely related to each other, but sundered in speech and culture a bit. To the extent that Middle-earth during the Second Age still made a distinction between relatives of those two houses, Beor's cousins were mostly in Eriador west of the Misty Mountains, whereas Marach's distant cousins were the ancestors of the northmen who later emerged as the men of Dale, Mirkwood, the Beornings, and most especially the Rohirrim. These could be seen as analogs to the Timischers and the Hill-men respectively.

Of course, I didn't do this on purpose, but it occurs to me that I did it on accident regardless. Maybe it's just too ingrained in my subconscious. Or maybe we're both looking at the same ethnogeneses of the European peoples. I thought of the first group as like until the EEF people, (Early European Farmers; descendants of Anatolian Hunter Gatherers who spread across Europe during the Neolithic) and the Colonists as not unlike the Indo-Europeans coming from the eastern steppes during the Chalcolithic and early Bronze Age. Of course, in my case, it happened much more recently, but it's still the same movement. Curious that Tolkien did the same thing; during his time, our understanding of the archaeology wasn't as strong. Then again, archaeogenetics is largely confirming what people in the early 20th century thought anyway and disproving the theories of the 60s and 70s that replaced those earlier theories.
