From the notes of Sarah Bird, Lillian Giulidan and Lena Marie Tiannen's "On the Ancients":
Humans of Tiriana already know that races came before them-that on the far regions of the world, in the isolated and wild places, races besides them once lived, and remnants of them still exist. In particular lands like Arraia (now modern-day Auroria, a bastardization of a word in a lost language that seems to have something to do with ethereal light), or Maraelir (meaning "isle of the ancients" in Middle Iliradian or Dol Lanaai in New Tirian), h'eAniai Tuillineh (meaning, literally, "Land of Fire and Ice" in Siaeih Nomhairi) or the islands of Komaira come to mind.
Let us bring to attention these remote lands of the far south of the world: Arraia. Its original natives called it that; it means, oddly enough, "heartland." And I use this name for that land very deliberately. Ancient Arraians (who called themselves Illionnin, the Returned), believed it was the center of the ancient, wild power, and that the land itself would hold up against any temporal tide that could wash against it. The Maraeliren have retained power through sheer strength and the Tuillineh have fallen into unending warfare, but the elusive Arraians (if you ever see one, and if you can manage to get more than a few words out of those hardy, dark and enigmatic people, for even Aurorians born and raised sometimes never see one or never realize they've seen one) will tell you quietly that the new powers are "tides" and Arraia is the "mountains and the desert" of all the world's power. It will, simply put, be there until some cataclysm ends Tiriana.
Danoaih Firewing, an ancient Arraian by pure blood and the only true one to speak publicly, said: "You do not recognize the power of the land you have taken. For though your powers are the tides, and though the tides may shape out the lands-what are the tides when the sky is stripped and the air is blackened again?"
He references the Xliiruunaao Wars, which almost no nonhuman race on Tiriana survived. And that becomes a question: How did the elusive Arraians, supposedly primitive, survive a nuclear war and beat the entire concentrated Xliirunaao forces back singlehandedly from the hidden reaches of their homeland? Oddly enough, humans only noticed Arraia's potential after the Xliiruunaao did.
Those who study the Ancients on Tiriana have come to take the old Arraians' claims a little more seriously. A good majority of that land's native creatures are near-sentient, some even recognized sentient species. Iannoa weavers figured out many scientific concepts before humanity rediscovered them, due first to the incredibly complex patterns inherent in their lives, to their high intelligence and extremely powerful senses, and to their natural insatiable curiosity. They understood a lot of things without needing so much of the equipment we needed to gain their knowledge.
The iannoa weavers are the most accomplished example of the sentience concentrated on Arraia. Khrinnoai are brutal strategists (though their form of it allows for their size and power; few other creatures could effectively pull off khrinnoa battle-strategy) and they have an established scent-language, which is not actually a basic form of communication, but a very complex one. Though intensely solitary by nature, such creatures have a network of communication fast enough to rival humans'. Their scent-language can communicate very specific quantitative and qualitative information, or for example very exact aspects of one's intentions and strategies and the movements of one's rivals. Khrinnoai simply never bothered to prove any level of intelligence to anyone.
And those are only two examples, though amusingly enough Arraia's near-sentient and sentient creatures despise the nonsentients introduced by off-continent humans, while they merely tolerate the ones they always shared their land with. Most who have lived out generations in that country develop an understanding-this is mine and this is yours, and should you interfere with what is mine I have the right to defend it, and vice versa.
Not only this, but the entire continent of Arraia is an energetic hot spot. Iannoa weavers tap into this pure, raw elemental energy all the time. Aurorians (the name given settled humans; Arraians refers specifically to the original peoples or to all intelligent life on the continent) say an angry iannoa weaver is more dangerous even than a khrinnoa, and not just because of their poison, but because they can summon a sandstorm and bury you without a trace, unable to escape. I have seen an iannoa weaver summon up a sandstorm, leaving some yet taking others who stood right beside one another.
Danoaih, whom I spoke to, was the main liaison between the iannoa weavers, his own people, and the humans who also settled on Arraia and called it Auroria. Danoaih aided Tirran Eilin in gaining closer understanding of the khrinnoai, but understandably no communication has been established between them and any race (even Eilin admitted that was an impossibility). They opened communications with the iannoai and the delicate little solinnai, whom the dolphins also helped us to understand, and potentially orchestrated the future of our entire planet.
