Greetings, illuminate, to Hysh. Land of reflection, light and wisdom. Hysh is the mortal realm of light and is conjointedly ruled by the twin gods Tyrion and Teclis. It also doubles as the mortal realms' sun. The Lumineth Realm Lords come from here.
The Ten Paradises of Hysh are lands of illumination, symmetry and reason; and their inhabitants driven to the highest of their paths through meditation, asceticism and self-improvement almost to the point of obsession. It also helped that Hysh's realmstone, Aetherquartz, is mortal-made and enhances the mental and physical properties of the user even further.
Between the Aetherquartz and the guidance of both Tyrion and Teclis, civilization in Hysh became incredibly focused in self-improvement, reason and order; each individual willing to great lengths to become more than they were, with the pinnacle of this being the Lumineth. Over time, the Lumineth became egotistical perfectionists who thought they'd overcome all their flaws, each leader considering themselves the best exemplar of their race and others as inferiors or rivals who needed to learn their place by any means necessary... wait, this mindset sounds familiar. Things went from bad to worse when certain someones came knocking...
Hysh’s radiance is so strong that it’s realmsphere is seen from all of the Mortal Realms and beyond as a blinding ball of pure light, and serves as the Realms' equivalent of the sun. However, both Hysh and Ulgu share an orbit (with the orbit's center being, hilariously, Shadespire) and periodically Ulgu eclipses Hysh, bathing the realms in darkness. And that, children, is how day and night works in the mortal realms (no word on how this works on Ulgu and Hysh themselves).
Unlike the other realms, Hysh has a weird relationship with the realm of shadow, Ulgu. Not only both move in the same orbit as seen above, but also there's a subrealm where the energies of both Hysh and Ulgu intermingle, mix and become something that even the deities of both realms cannot fully comprehend. This paradoxical realm is called Uhl-Ghysh and with the weird properties found here, Teclis found the location perfect for his plan of trapping Slaanesh and make him/her/it throw up elven souls. Currently, as the cage of Slaanesh, is nearly impossible to get to Uhl-Ghysh, but between the machinations of that bitch and the Necroquake, the illusions that conceal the paths there are unraveling.
The coming of the Lumineth Realm-Lords gave us a complete map for Hysh, being the first realm to do so. This tells us that either it is a much smaller Realm than the others, or that each nation has to be fucking enormous. Either way, the Ten Paradises are arranged as two perfectly symmetrical halves, with one half influenced by the teachings of Teclis and the other by Tyrion. The remaining two, Xintil and Haixiah, are presumably under the jurisdiction of neither individual god.
The centre of Hysh where magic is most stable and least likely to explode everywhere. It tends to be where the majority of the non-Aelven races live.
The people of Syar are some of the greatest craftsmen in the Mortal Realms, and people travel far and wide in order to purchase their magical trinkets.
A matriarchal society with a heavy emphasis on improving through generational growth, so women are revered. To get around
the inconvenient fact that a woman needs a man to get pregnant in the first place childbirth - which was considered a messy, painful distraction, they invented magical soul-splitting cloning to replace sexual reproduction (yes they literally thought they were too good to give birth; insert obligatory joke about career women or feminists here). This was abused during the Age of Myth in an unspecified way and became closely regulated. It’s the most populous of the Lumineth kingdoms as a result and twins are very common.
The Lumineth of Ymetrica are a warrior culture (kind of odd for being on the Teclis half of the map) as tough as the mountain spirits they worship, being the First Nation to buy into Teclis’ whole Aelementari scheme. It is said that there is never a time when the forces of Ymetrica aren't fighting somewhere in the Mortal Realms. A more close to home threat for this nation comes from the Stoical Vast mountains. A great Troggherd called the Stoical Gobblemaws makes regular advances across its peaks in hopes of devouring all of the mountains. They and their Troggboss Gorp have been pushed back by the Alarith temples, but they just keep coming. Additionally, there are the flesh eaters of the Vertigon Court, who have settled in the Vertiginous Peaks. The Lumineth surprisingly are content to let these ghouls fester and squabble amidst the mountains, acting as an unwitting buffer zone against any chaos invasions.
They're the powerful mystics even amongst the Lumineth. They also seem to be pretty close to the Celennar.
The Realm's Edge of Hysh, described as a place of freakish perfection. The fjords themselves are rimmed with fractal patterns, and going deeper you'll find places that exist as pencil sketches, dots of light or waves of thought. No Lumineth lives here, as this was a place no mortal was meant to tread. When Tyrion, the literal god of Light journeyed to this place in search of Teclis, he was blinded. The God of Light was blinded. Really puts it into perspective.
