 * Ornn Terraforms the land what will eventually be called the Freljord.
 * Origins of Snow.
 * Ornn constructs his home and calls it "Horn Hall".
 * Anivia, annoyed by Ornn for he had felled her favorite perching trees to build his home, decided to teach him a lesson. In an attempt to tickle Ornns nose with her feathers, she had caused Ornn to sneeze a gout of flame that set fire to the bedsheets of his bed that spread to the flood. Anivia panicking, flapped her wings to fly away, but this only stoked the fire hotter with the dry Freljord air. Soon, all of Horn Hall was alight. The fire raged for days, darkening the skies with ash while Ornn slept through the whole thing. He awoke atop a pile of ashes in a very bad mood. But he did not know what Anivia had done. And to this day, she has never told him the truth.
 * Ornn sought out to construct his second home, with non-flammable material. He fashioned himself a spade, a lever, and a fork. With these tools, he could dig for ore, move mighty pillars, and eat the delicious spiced cherries he so enjoyed.
 * He hammered and shaped chunks of ore until a black mountain stood. Inside was a great forge that channeled the primordial molten flame from deep within the earth. He was pleased with his new home dubbed "Hearth-Home".
 * Due to his home being hotter for even Ornn to endure, he dug a trench from the sea, straight to the mountain. The Seal Sister allowed cold waters to rush through the trench and cool the Hearth-Home. Great plumes of steam rose up. It took three days for the mountain to cool enough for Ornn. In that time, the ocean that fed the river dipped several inches.
 * So much steam had risen from the waters that the perpetual blue sky was mottled with darkening gray clouds. As these new puffy forms gathered and cooled, they grew heavier and heavier until they burst with snow.
 * It snowed for a hundred years, being the primary reason as to why the land later called the Freljord is covered in snow to this day.
 * Creation of Yordles.
 * arrived on Runeterra.
 * Creation of modern Humans.
 * Creation of the first human settlements across Runeterra.

History

Ancient History
Events from the creation of human writing to the fall of Shurima.
 * The settlement of the Hearthblood was founded by a croup of humans that wanted to dedicate their lives in crafting various weapons, tools, and objects. Their settlement was build under the mountain where Ornn's Hearth-Home was located.
 * Founding of the Freljord_Crest_icon.png Kingdom of Freljord.
 * By this point humans have at least begun to colonize large areas of Runeterra for themselves, and tribes of humans can be found in the Freljord, sharing their lands with Ursine and Frost Trolls, who first appear in recorded history at this point.
 * Destruction of the Hearthblood.
 * Volibear demands of Ornn for his workers to create weapons of war for him. With Ornn's refusal of such request Volibear took a piece of armor from the walls of Ornn’s forge.

 * The Death of the God-Willow and the Birth of the Green Father.
 * Before the Frozen Watchers can take over everything with their Iceborn horde, Ivern sets out to search for a means to stop them, travelling to the fabled land of Ionia, which is said to be filled with magic. Here he and his fellow warriors are escorted by the natives to Omikayalan, where the God-Willow is found. The Vastaya of the land slaughter Ivern's followers but Ivern strikes at the tree, killing it but being transformed himself into the next God-Willow.
 * Watchers enslave the Freljord.
 * The Frozen Watchers appear in the Freljord. It is a mystery where they came from and why they came to the Freljord, though they set about transforming the native human population in to the iceborn, who are exceptionally long lived and have incredible magical powers. The iceborn are tasked with creating an empire for the watchers, which they do, plunging Valoran in to an ice age which presumably lasted for several centuries.
 * his marks the first time in recorded history where true ice is used as a material for creation, and with it various tools and weapons are made by the iceborn. Artifacts such as the Frozen Mallet, Seeker’s Armguard and the Frozen Heart likely originated from this era.
 * Three human sisters, Lissandra, Serylda and Avarosa become iceborn during this time, becoming important figures in the empire. Lissandra as a human was blinded by an ursine’s claws and thus is wholly committed to the watchers for giving her a form of sight again, who elevate her to the status of “Seeker”, their mouth piece to the people.
 * Two of the three sisters ask for aid from Ornn to help them fight against the Watchers. Avarosa was the initial instigator for this request and Serylda request for the creation of a bottomless ravine.
 * Iceborn Rebelion against the Watchers.
 * Avarosa led a rebellion to overthrow the Watchers, which culminates in a battle close to Ornn's bottomless ravine. The battle ended with the Iceborn throwing the The Frozen Watchers are thrown into the ravine.
 * The three sisters requested from Ornn to constrict a massive bridge overlooking the Frozen Watchers in the ravine. Ornn, using a hammer constructed from a meteor gifted by the three sisters, built the bridge on his own. The bridge, was named “The Howling Abyss” (as the event was always remembered as when they threw the watchers “howling in to the abyss”). Howeever, without Ornns permission the Third Sister walked the length of the bridge, reciting strange incantations across the entire span. This turned the bridge into a crossbar that sealed the beasts below within the abyss, ultimately structurally weakening the bridge. The Three Sisters vowed never to speak of Ornn again.
 * Ornn, meanwhile, realized he did not like people asking him favors, and threw his spade as far to the west as he could. Where it landed, no one knows, and its fate is lost to darkness.
 * Then he turned east and threw his favorite eating fork as far as he could. It landed in the Great Sea. Later, a mer-king found a powerful trident at the sea-bottom, and still uses it to rule his kingdom.
 * Following this Avarosa becomes the Frost Queen and rules the iceborn’s empire for an unknown period of time.
 * Artifacts such as the Guardian’s horn and the Frost Queen’s Claim originate from this time period.
 * The War of the Three Sisters.
 * Disagreements between Avarosa, Serylda and Lissandra eventually culminate in to a civil war that destroys the empire the iceborn built. Avarosa is killed, Serylda’s fate remains unknown, Lissandra goes in to hiding, corrupting a human tribe called the Frostguard for her own goals.
 * The iceborn descend in to bitter infighting between tribes, and with no leader to unify them the empire collapses entirely.

 * Events leading to the Birth of Progress Day.
 * Zaun finalizes it's plans to destroy a portion of the isthmus connecting Valoran and the Southern Continent, allowing for safe sea passage between eastern and western Valoran. The plan involved using thousand of chemtech bombs to crack open an area of the land such that a cavern could be created, but the results were catastrophic, as in what seemed to be an accident the bombs triggered a series of earthquakes that completely destroyed the isthmus and sank large districts of Zaun and thousands of its citizens, while also leaking poisonous gas in to the city's surviving areas.
 * , empowered by the prayers of Zaun's people, arrived and blew away the gas, saving many lives and being eternally remembered by Zaun's denizens, converting her from a goddess of faith for sailors to a guardian deity for Zaun. She has yet to leave Zaun following this event.
 * Eventually Zaun was rebuilt. In order to regulate the oceanic passage they were built over, the Sun Gates were constructed, forcing all transport through the waters to be regulated by Zaun. This brought immense wealth to the city and likely led to Piltover's construction and elevation from Zaun, as the merchant clans were in control of most of the money coming through this trade route.
 * Construction of the Sun Gates led to great changes in eastern Valoran and the eastern seas, as Noxus was from this point on able to more easily pool together resources from across its empire without needing land travel, and Bilgewater's pirates found the seas brimming with trade ships waiting to be plundered, feeding in to the criminal underbelly of the city.
