Raverion is often dubbed "the Gem of the North", for it resembled and emulated the lost elven city of Myth Drannor in many respects. It was one of the few civilized places in the middle of the rough and untamed wilderness that was the North of Runeterra. It has a rich cultural life and was renowned as a meeting place for all races that were morally inclined towards good. Raverion is also famous for its pervading tradition of magic, and was home to many notable wizards, sorcerers and other mages. Raverion was built and ruled by high elves and have become much more hospitable in the recent decades. Explorers are sent out to seek out knowledge about the world to come back to expand the libraries of Raverion as the nation gives importance to knowledge as they believe that with sufficient knowledge, they will outlast the world.
Undermountain, dwarven regions of mining. Chroniclers say that the tunnels and mining networks are extensive that reaches from Xagos to Ensvale (this should be look into) and deep that minerals of every kind can be found down the mines of Daghladuhr. They claim to be a nation independent from Xagos (but Xagos says otherwise). This is where Xagos gets its metal and some criminals hide under the infinite tunnels beneath.

CRASHPOINT
Crashpoint, also known as the City of Iron and Glass, is a large, undercity district, lying in the deep canyons and valleys threading Oseron. What light reaches below is filtered through fumes leaking from the tangles of corroded pipework and reflected from the stained glass of its industrial architecture. Crashpoint and Oseron were once united, but are now separate, yet symbiotic societies. Though it exists in perpetual smogged twilight, Crashpoint thrives, its people vibrant and its culture rich. Oseron's wealth has allowed Crashpoint to develop in tandem; a dark mirror of the city above. Many of the goods coming to Oseron find their way into Crashpoint's black markets, and hextech inventors who find the restrictions placed upon them in the city above too restrictive often find their dangerous researches welcomed in Crashpoint. Unfettered development of volatile technologies and reckless industry has rendered whole swathes of Crashpoint polluted and dangerous. Streams of toxic runoff stagnate in the city's lower reaches, but even here people find a way to exist and prosper.
SILKVILLE
This settlement has since evolved from a small town to a city-state. With its features of a central spire that is impossibly tall and narrow, centered on the city that is believed to be where adventure can be had, its history rich with drow culture (both good and bad ones), and it being built on top of many dungeons and a forgotten dwarven city named Dwarvenhearth. It is said that the subrace of drow came from here from the myth that is known as the Underdark. Lots of mercenaries and explorers say that beneath the city through the spire is there they can find the blocked entrance to the Underdark. Chaositech and strong quality silk (spun by species of arachnids found only in Silkville) can be found here.
IXALA
Renowned for its mastery of elemental magic, Ixalan culture is much older—part of the great westward diaspora that gave rise to older civilizations and it is likely they played a significant role in the creation of the first mortal-born God. Now, secluded deep in the jungle for thousands of years, the sophisticated arcology-cities of Ixaocan remains mostly free of outside influence. Having witnessed from afar the ruination of its neighbor, Eji'sal, the Ixalans view all the other places of Runeterra as upstarts and pretenders, and use their powerful, raw, elemental magic to keep any intruders at bay.
A weird region in the middle of Runeterra. It is comprised of tribes from all over its neighboring regions that found solace on the swamps and humid forests far from the deserts and the magics. A new-ish region which cities that are relatively, newly made with the intent of being a safehaven from the world. Most of the cities are close to the coastlines and some are deep in the swamps are wherever there is water. (The archivist also says that not much is known of this place as it popped up one day; need more data)
The empire of Eji'sal was once a thriving civilization that spanned a vast desert. After an era of growth and prosperity, the fall of its gleaming capital left the empire in ruins. Over millennia, tales of Eji'sal's glorious city became myth and religion among the descendants of the scattered survivors. Most of the nomadic inhabitants of Shurima search for basic sustenance in an unforgiving land. Some defend small outposts built around a few oases. Others hunt buried riches among the ruins of the fallen empire, or obtain mercenary work, taking coin for their deeds before disappearing back into the sands. Now, the tribes are stirred by whispers from the heart of the desert: the city of Shurima has risen again.
Started long ago as a nation of merchants from Zamora in which wealth is power. Now, the merchants rule and split the region into provinces in which all have their own specialty to what they sell like cloths, magical items & trinkets and even services such as mercenary-work or gambling services. The Silk Road, a popular route in which merchants travel onto was made here. It should be known that there is a location that Khalabaster-21 was sent to; the hidden city of Suginia. (It is of significance that we get information on this hidden city whether it is true or not)
Like any place of myth, Godreach is a beacon to dreamers, madmen and questors of adventure. A mountainous, sparsely inhabited region, as it boasts the tallest peak in Runeterra. Located far from civilization, the Godreach is all but impossible to reach, save by the most determined pilgrims, chasing some soul-deep yearning to reach its summit. Those hardy few who survive the arduous journey to the foot of the titanic mountain find a sky shimmering with celestial bodies; the sun and moons, but also constellations, planets, fiery comets that streak the darkness, and auspicious arrangements of stars. Some return haunted and empty, some changed beyond all recognition, and some don't return at all. The people living at the mountain's base believe these to be aspects of long-vanished stellar beings, creatures powerful and ancient on a scale beyond human comprehension. Its people unsure of what happens when you reach the peak. Do you meet the Gods or do you become one?
