Figured this might be of use for those who have not up to now been aware of this game and it's amazing story. I think I fixed all the spelling mistakes after I copied and pasted it below. For more details Kaze No Shiro has all the fictions ever made for L5R.
Dawn of the Empire
As the mortal realm is formed by the actions of the Lady Sun and the Lord Moon, their children become the object of their father’s burning jealously. Lord Moon consumes nine of the ten children, but Hantei frees his siblings at the cost of sending them plummeting to the mortal realm. There, the Kami discover the world of men and women, and soon Hantei becomes the first Emperor of Rokugan even as his brothers and sisters form the seven Great Clans to serve him. The Crab, the Crane, the Dragon, the Ki-Rin, the Lion, the Phoenix, and the Scorpion clans all swear to serve the Emperor so long as the Empire remains. Unfortunately, one of the Kami fell apart from his siblings. Emerging from a festering pit far south of Rokugan, Fu Leng is much changed by exposure to the Realm of Evil. Monstrously powerful, Fu Leng raises an army of inhuman creatures and wages a surprise attack against the Empire that very nearly destroys it. Fu Lengs army very nearly succeeds, and is only stopped by the Little Prophet, Shinsei, Seven Thunders, exceptional individuals drawn from all seven clans. The Thunders defeat and bind Fu Leng’s power, but at the cost of their own lives.
Scorpion Clan Coup
Fearing a terrible prophecy that calls for the end of the Empire to come at the hands of the Hantei Dynasty and succumbing to the seductive whispers of the Bloodsword, Ambition, the Scorpion Clan Champion Bayushi Shoju plots to seize control of Rokugan from his friend and lord, the Emperor Hantei XXXVIII. Secretly moving troops into the Imperial City by the thousands, Shoju meticulously plans every aspect of his usurpation, including poisoning the Lion Clan Champion Akodo Toturi, the one man that Shoju fears can bring his efforts to ruin. With less regret in his heart than he had anticipated, Shoju kills the Emperor and seizes control of Otosan Uchi. All does not go as Shoju had planned. The attempt on the Lion Champion’s life fails, and the Crab, whom Shoju had hoped would join him in his effort to depose the weak and ineffectual Hantei XXXVIII, side with the other Creat Clans to break his stranglehold. In the end, the Great Clans defeat the Scorpion forces holding the city and Shoju is killed by Toturi in a duel. Hantei XXXIX, who survived the coup, disbands the Scorpion Clan for Shoju’s crimes.
The Clan Wars
Crippled by a terrible plague, the Empire languishes as the Imperial families are decimated and even the Emperor, secretly poisoned by his Scorpion bride, is stricken by the wasting disease. Disgusted by the weakness he sees in the Empire’s rulers, the Crab Champion is manipulated into an alliance with the Shadowlands in order to seize the throne, and leads a massive army north bent on conquest. The ambition of the Crab, combined with the wrathful vengeance of the Scorpion who have remained in hiding since their clan was dissolved, soon throw the Empire into a state of all-out war, a war that the forces of Fu Leng use to great advantage in order to advance their own agenda. As the war advances, the Emperor is possessed by the spirit of Fu Leng. Almost too late, the Great Clans unite against this new threat, and the reincarnation of the Seven Thunders are led by the descendant of Shinsei, the Little Prophet, to defeat the Dark Lord once again. The ronin Toturi, former Lion Champion and the Lion Thunder, takes the throne as the new Emperor, Toturi I, elevating the Mantis to a position as a Great Clan for their valor in the battle for the throne.
Hidden Emperor
The Emperor Toturi disappears suddenly, prompting chaos in the courts as speculation runs rampant as to who could be responsible for such a thing. Fingers are quickly pointed at the Scorpion Clan, who are soon banished from the Empire for their assumed complicity. What none suspect, however, is the hand of an entity older than mankind itself: the Lying Darkness, a being of the primordial nothingness that existed before the mortal realm was created, and which desires only to return all that is into absolute oblivion. With its ability to consume the identity of others, to absorb them into itself and create duplicates to take their place, the Darkness soon pits the Great Clans against one another in a deadly game of war and intrigue. When it seems that the Great Clans are on the brink of discovering the truth, the Lying Darkness takes steps to ensure that its destruction of the realms is complete. By opening the ancient gateway between worlds known as Oblivion’s Gate, the Darkness will destroy the ancestral spirits of the Empire, crippling and demoralizing the samurai caste and rendering them far easier to subvert. In the end, however, Darkness is defeated, and while the mortal realm suffers significant damage, it remains intact.
The Four Winds
The Splendid Emperor, Toturi I, is unexpectedly attacked by a force of oni while visiting the Scorpion lands and is slain, never having formally recognized which of his children he chose to succeed him. Many speculate that Toturi was en route to finally acknowledge Akodo Kaneka, long having claimed to be the Emperor’s illegitimate son, as one of his children. Speculation among the clans immediately begins as to which of the Emperor’s four children is most fit to succeed him, and an entire generation of samurai, having grown complacent after a generation of relative peace, begins to factionalize to support the one that they believe most worthy to sit upon the Emerald Throne. The honorable Toturi Tsudao, the bitter Akodo Kaneka, the cunning Hantei Naseru, and the powerful but unhinged Toturi Sezaru spend two years gathering power and plotting against one another, some more overtly than others, before the fifth contender for the throne, the last true scion of the Hantei bloodline, the Dark Lord of the Shadowlands, Daigotsu, threatens the whole of Rokugan. The Four Winds unite against Daigotsu and kill him, albeit briefly. Toturi Tsudao perished in the battle, Hantei Naseru becomes the new Emperor of Rokugan, and both Kaneka and Sezaru join the Phoenix, the clan of Toturi’s wife, Isawa Kaede.
Reign of Blood
Throughout Rokugans history, there have been few threats more terrifying than that of Iuchiban, the Bloodspeaker. Born of royal blood and possessed of a singular desire to shape the world in a manner of his choosing, the dreaded blood sorcerer escapes once again and quickly displaces the Dark Lord of the Shadowlands as head of the forces threatening to destroy the Empire. Manipulated by the Shadow Dragon, a creature of pure deceit and malevolence, Iuchiban brings a Rain of Blood to the Empire, corrupting hundreds and turning the clans against their own ranks in an effort to contain the new evil within themselves. Iuchiban’s influence further exacerbares the imbalance created by the opening of Oblivion’s Gate, and ultimately culminates in a new spirit realm, the Realm of Thwarted Destiny, being created. The legendary hero Hida Kisada emerged from the Gate to end Iuchiban’s threat and restore the proper balance, allowing the Realm of Thwarted Destiny to stabilize without the corruption of the Bloodspeaker or his twisted advisor, the Shadow Dragon, to take hold.
Age of Enlightenment
As the Righteous Emperor, Toturi III, reigns over Rokugan, a sort of spiritual malaise afflicts its people. Aware that the clans are losing their way, the descendant of Shinsei, a man named Rosoku, return to the Empire prematurely. Rosoku is assassinated by the Shadowlands, but not before he conceals five sacred tomes throughout the Empire. A search takes place, with the five samurai who finally find the books taking on the mantle of the Keepers of the Elements, tasked with guiding the spiritual development of the Empire. Under their direction, the search for enlightenment becomes something of a fad among the people of the Emerald Empire. The Age of Enlightenment comes to an end as the Emperor and many of his servants convene at the formerly-mythical Tomb of the Seven Thunders, deep within the Shadowlands. There, the Emperor discovers many ancient artifacts that are essential to the Empire’s survival. He sacrifices himself to allow his servants to bring these artifacts back to the Empire, with many great servants perishing alongside him, although their sacrifice obliterates legions of oni bent on their destruction.
Race for the Throne
The death of the Righteous Emperor at the Battle for the Tomb in the Shadowlands was a terrible blow to the Empire, and in its aftermath, the Unicorn Clan Khan, Moto Chagatai, attempts to take the Throne to give the Empire a strong ruler, a gambit that failed, and led to the death of every member of the Toturi line. Recognizing that fate had thrust them once again into a position where the throne of Rokugan was available for the taking, the Great Clans immediately began to seek a means by which they could host the next Imperial Dynasty. As they did so, the former minions of the Shadowlands conspired to create a new conspiracy, masquerading as the nascent Spider Clan. Even as the clans plotted, however, the Celestial Heavens moved to restore a balance that had been disturbed for generations. The former mortals occupying the position of the Sun and Moon were cast down, replaced by the Jade Dragon and Obsidian Dragon, respectively. The Heavens demanded a return to the traditions of old, and convened a Celestial Tournament to remind the mortals of their origins. At its conclusion, the samurai Kitsuki Iweko was chosen, and ascended to the position of the Divine Empress Iweko I.
The Destroyer War
The malevolent intelligence that is Jigoku, the Realm of Evil, loses faith in its champion Fu Leng after his repeated failures, and withdraws its support. Instead, it chooses the demon goddess Kali-Ma, an entity that has destroyed the other members of her pantheon and brought complete ruination on the entire nation of the Ivory Kingdoms. With an unimaginably vast army of soulless, ironclad destroyers at her command, Kali-Ma marches upon Rokugan, entering from the south and shortly overwhelming the Crab defenses to push farther into the Empire. United by an enemy so dire it threatens the entire Empire, the Great Clans unite and face the forces of the Destroyer goddess in the Scorpion lands, which are soon churned into a blood-soaked wasteland by the constant warfare. Manipulated by the mortal incarnation of Fu Leng, a small group of young samurai inadvertently release the last bit of Kali-Ma’s power, making her stronger but also mortal, and although she kills Fu Leng, she is destroyed by Daigotsu after he takes his own life in an agreement with the Empress. The Destroyer is killed, the Spider Clan is formed, and the Empire for the first time sets its sights upon new lands: the former Ivory Kingdoms.
The Age of Exploration
Twenty-five years after the conclusion of the Destroyer War, the Empire is a much different place. The former Ivory Kingdoms have been heavily settled by Rokugani interests. Now known as the Colonies, the former kingdoms are adjudicated by an Imperial Governor, one of the most powerful people in the world other than the Divine Empress herself, and their boundaries are constantly pushed forward by the Empresses servants among the Spider Clan, Tainted warriors no longer welcome in the Empire but permitted to serve in the Colonies. Alongside the Mantis and Unicorn clans, the Spider form the bulk of the Empress forces in the Colonies. Within the Colonies, the clans encounter the Fudo cult, a sect of the Brotherhood of Shinsei long since banished from the Empire. Although they do not realize it at first, the samurai of the Colonies quickly become embroiled within a confiict between the Fudoists and the mad dragon, P’an Ku, a celestial force of absolute insanity that has plagued the Empire on occasion throughout history. Many fall to the heretical philosophy, and even more to the dragon’s seductive insanity, before order can be restored. In the end, the dragon is banished from the mortal realm and the cult is driven into hiding, but the damage done in the process is substantial.
A Brother’s Destiny
The gulf between the Empire and the Colonies grows ever wider, and when fate conspires to bring both sons of the Divine Empress to the Colonies, the samurai there quickly fall into two camps: one supporting the traditionalist Iweko Seiken, trained among many different clans, and another supporting the more progressive and less conventional Iweko Shibatsu, reared by the Spider Clan in the most sacrificial of Iweko I’s concessions to the Dark Lord to establish peace at the end of the Destroyer War. Although at odds with one another philosophically, the brothers do not wish to wage war upon one another. Unfortunately, their supporters do not share such reservations. Far from the watchful eyes of the Empire, the samurai in the Colonies quickly fall to skirmishing and then to all-out war with one another over their divided loyalties. The Crab and Lion immediately take the field for Seiken, while the Spider and Mantis support Shibatsu, with the other clans divided almost evenly between them. Several major battles are fought before the Empress emerges from seclusion to declare which of her sons she has chosen to succeed her, beginning a great period of celebration throughout both the Empire and the Colonies.
